How does the odometer work?  The system counts all wheel rotations and then multiplies the digits by tire circumference. The final number is the total covered distance. Using this method, it is easy to measure the miles that a vehicle has covered. The device can be mechanical (mostly in the past), electronic or combined.

Although it may seem that you need an advanced device to do the same calculations, it started in the 1600s. More precisely, in 1645 Blaise Pascal created the Pascaline. It was the predecessor tool of what we use nowadays. So, how do odometers work according to Pascal? Those old calculators used mechanical gear wheels instead of modern digital technologies to do quick arithmetical calculations. The gears were a chain of 10-toothed wheels. Rotation of the first gear automatically pushes the next one to start moving as well and the process continues repeatedly. 

After France, a more similar development took place in the United States. The first real signs of an odometer can be found in the 1770s. how does an odometer work from this point on and what was its major function? In the US they used a small device that was inside the postal carriage. It was helpful to measure the distance of any postal route and it was the main purpose. In the 1840s, Clayton and Pratt finished working on their previous mockups and advanced their work. Later it was used in wagons to measure the distance traveled during a journey. Due to its effectiveness, it gradually became more common practice all over the country.

how does the odometer work? Today cars use the modern gearbox to show accurate distance. thanks to new technologies the system calculates everything instantly and displays the appropriate numbers on your dashboard.

How does the odometer work? – The importance of an odometer

Everyone knows what a speedometer is and they can answer you without a second hesitation. However, many still do not know how odometers work and how much importance it has. That is why you need to answer the question how do odometers work? It counts the distance traveled (miles or km) by an automobile. To do so, it uses the tire size times wheel rotation. The final number will be the covered distance. Hence, an odometer is the one that is responsible for correctly measuring the distance. Odometers are extremely important because if a car does not have a proper odometer, you will not be able to detect the mileage.

To make sure that everything works flawlessly odometers work closely along with the speedometers and the tachometers. Both of them have crucial roles as tachometers count the rotations and speedometers measure the speed. Gathering all the information makes it possible to calculate the distance. Since you already have an answer to the question “how does an odometer work?”, you may think that there cannot be an issue at all. On the contrary, there are several factors that can affect the correct mileage.

At first, vehicles have new tires, however, after a certain period, it gets worn out. It is important since the worn-out tires have less circumference and the system will calculate the incorrect data. Moreover, People nowadays ask “how does the odometer work?” But more important is what happens to a vehicle if it does not work properly. Mileage reading is useful in many things one of those is the oil change. After a certain amount of mileage, you need to change the oil. It is crucial for the maintenance of any auto. So, if you don’t know exactly how much you have covered, you cannot say whether you need an oil change or not. Therefore, you have to always check the overall wear and tear to make sure that the odometer works flawlessly and avoid any misunderstanding or false information about the mileage.

What is an odometer Fraud?Everything about the odometer fraud

Actions that cause odometer malfunction and make the system show incorrect mileage is an odometer fraud. Once people answered the question “how do odometers work?” and realized its importance, some decided to interfere with its normal functioning and force an automobile to display misleading mileage. This is becoming common day by day and has already become one of the most important challenges in the 21st century.

We pay too much attention to the mileage and it influenced our lives. Whenever you decide to buy a new auto the distance is one of the first things you will check. There is no doubt that it is important, but remember that odometers do not always show the correct data and people usually manipulate them to increase the resale price.

Odometer fraud, also known as “clocking”, is well-researched but still unsolved. Individuals roll back, freeze, reset, or remove mileage from the dashboards. They use various tools to achieve their goals and all of them are illegal. That is why the German team of SKF has researched a common challenge “how does an odometer work?” and created an advanced product – Mileage Blocker. It simply stops counting up miles and does not change any system function or delete previously recorded data. This is why car manufacturers use them. But remember that it is only for testing or tuning purposes and using it on freeways is illegal and unethical.

Other gadgets remove or roll back the digits from the dashboard. Hence, you will see the lower distance on the instrument cluster and may believe that the car is new. In fact, you will be yet another “victim” of a scam. 

how does the odometer work? Can I check if someone altered an odometer? These are the questions that a lot of auto owners ask.

What makes people reset an odometer?

We all know that mileage is important when we speak about automobiles. Its huge importance is exactly what pushes people to manipulate odometers. We have to discuss the main reasons behind the common fraud. Meanwhile, if you wondered how do odometers work? we have an answer for you. It detects the rotation of the wheel and determines the exact distance that this vehicle has covered in miles. Knowing the exact mileage is essential and it helps you keep your car in good condition. However, some still try to artificially adjust the original digits and they have several reasons for this:

One of the most significant reasons is the price difference. Autos with less mileage have higher resale prices compared to the ones with higher kilometers. Hence, if the owner considers selling his or her vehicle soon, it may be tempting to change the numbers and make a better profit.

Secondly, insurance companies charge people according to the distance. The higher your mileage is, the more you have to pay. To avoid high paychecks, people roll back odometers. Tampering odometers is illegal but still, it is a common solution against high taxes.

Do car manufacturers and dealers know how does an odometer work? Yes, they know exactly how it works and they usually halt an odometer reading during testing. It avoids extra miles and guarantees that everything goes smoothly at the same time. Plus, it would be very frustrating if you buy a brand-new vehicle and you find out that it has already covered some distance.

To sum up, there are three major reasons behind odometer fraud: 1) increasing resale price; 2) avoiding extra payments to insurance companies; 3) testing and tuning. 

Legal aspectsLegal aspects of the odometer

A lot of people reset odometers. But do local authorities know everything about it? how does the odometer work and is it against the law? There are the questions that they should focus on. An odometer always shows accurate information unless it is broken or someone manipulates its reading. If this happens it is a fraud and the person responsible will face criminal charges.

In the United States, it is a federal crime and depending on the state anyone will face fines or jail time. It is illegal in most European countries as well. Everyone should avoid the following:

  • Altering mileage – disconnecting an odometer;
  • Using a car which has incorrect mileage;
  • Selling a vehicle with a misleading odometer;
  • Forging official documents, such as odometer disclosure;
  • Conspiracies about “clocking”.

To avoid legal disputes and prevent fraud you should always follow recommendations from local authorities. It will also be beneficial to research more about legal aspects. Since you already have an answer to “how do odometers work?”, it will be easier for you to detect fraud and cars with misleading speedometers

Mileage blocker

A lot of companies on the market tried to create a device that would change the mileage without a system malfunction. Despite numerous attempts all of the existing methods use the same approach: rolling back, speedometer calibration, removing, deleting or resetting the mileage. That is why a team of professionals from Germany have developed the Mileage Blocker. This advanced tool from the official Superkilometerfilter stops counting up new miles while a car is in motion. More importantly, it does not delete or roll back existing data (which is illegal). It has some additional unique characteristics:

However, always have in mind that the mileage blocker is only for auto testing and tuning, and using it on free highways is unethical and illegal. If you have any questions you can contact us through the official website.


how does the odometer work? – it uses tire circumference and wheel rotations. Then the odometer multiplies them and measures the mileage. This is the fastest way to measure distance and all vehicles use this method. However, people with fraudulent purposes use devices to manipulate odometers and display wrong numbers.

Fortunately, there is a tool Mileage blocker, that does not remove or delete existing data. It simply halts the mileage recording process while a car is in motion. Mileage blockers are available online and you can purchase them anytime. Its unique features make it prominent from other devices on the market. Remember that SKF has developed it for testing and tuning – using it on freeways is illegal. In case of any additional information, please contact the support team.

What does the odometer of an automobile measure? An odometer measures the total distance that an automobile has covered. The odometer is a small device inside a car, usually placed on the instrument clusters. It can be electronic, mechanical or mixed. Thanks to new technologies, it counts wheel rotations and multiplies them by tire circumference. To identify the circumference, you should multiply tire diameter by pi (commonly known as “π” and equals 3.14159265359). The final digits are the total distance. Please take into consideration that if the tires are worn out their diameter will not be the same as the standard ones. Hence, the results will not be 100% accurate.

So, what does an odometer of an automobile measure? – It measures the distance covered by a car. Counting those miles and kilometers is more important than it looks. For instance, it is unquestionably true that mileage is the most effective way to monitor oil changes. Without correct measuring, detecting when the oil level is below normal would be harder. Therefore, odometers have a crucial role in car maintenance and you should make sure that it always functions flawlessly.

To sum up, now you already have an answer to the question “what does the odometer of an automobile measures?” An odometer is a tool that counts wheel rotations and detects the total distance traveled by a vehicle. This information is essential for normal functioning and maintenance purposes as well.

What does the odometer of an automobile measure? Is it the same as speedometer?What does the odometer of an automobile measure? Is it different from speedometers?

When you hear a speedometer, you know exactly what we are talking about. Simply it is a device that measures speed. The question is what does the odometer of an automobile measure? It meters the total covered distance. From now on you will know the difference between these two crucial elements.

In the past, people tried to develop a mechanism like modern odometers. They used early forms of tools to measure distance. For example, in the United States, companies installed gadgets on train wagons to calculate the exact length of a route. On the other hand, in England, post offices used them to gauge the range between post offices. Technology has gradually developed and we have modern odometers. The term itself comes from the 18th century. Modern devices are faster and more efficient than their older versions.

So, what does an odometer of an automobile measure nowadays? Modern odometers compute the distance moved by vehicles. Because of the advanced technologies the systems collect and measure all the necessary information in no time. In comparison, people had to make calculations mechanically to measure speed or distance which requires more time. In the 21st century, when everything is becoming more digitalized, electronic mechanisms do this “dirty” job more efficiently.

Thus, a speedometer and an odometer are two completely different devices. To understand the difference, you have to answer the key questions: what does the odometer of an automobile measures? It measures the total distance recorded while a car was in motion. On the other hand, digital speedometers measure the speed at a certain time. 

Why are odometers important?

We all know that the miles on a car have huge importance. Everyone tries to buy an auto with less total mileage. To understand the significance of mileage we need to answer two questions: why miles are important? And what does an odometer have to do with the mileage?

Let’s start with the first one. Many people believe that mileage is the most important element. Some only look at the miles and decide whether they buy it or not. This is based on the misconception that higher mileage is always bad and means more maintenance costs. However, you should know that modern cars can cover further distances without an issue and you should concentrate more on their usage. For example: under what conditions and terrain the owner used an automobile.

Moreover, less mileage means a higher resale price. That is why a person who plans to buy and then sell it in the near future always prefers a vehicle with a lower recorded distance. Plus, most insurance companies calculate their service based on mileage. If you drive more, then you have to pay more for their service.

As we determined the importance of mileage, it is time to discuss the second question. What does the odometer of an automobile measure? The odometer is a device on the dashboard that is responsible for correctly measuring the total covered distance. Therefore, when we see the numbers on a control panel it is thanks to odometers.

All in all, miles and kilometers have a crucial role in our life. That is why knowing the exact distance is crucial for an owner. An odometer is a tool that solves this problem for you and measures the total distance.

Is it legal to change the odometer?

Odometers are important and they have a significant function. what does an odometer of an automobile measure? It calculates the total distance traveled by a vehicle. Despite being so important a lot of people try to change those numbers. They use various methods such as resetting, freezing, rolling back or deleting digits. The main goal of these actions is to manipulate the odometer and artificially change the digits. 

Odometer fraud is becoming more and more common every year. It has become a huge challenge both in the United States and the European Union (EU). The cases of such fraud are constantly increasing and damage is worth billions of dollars. To fight against it the federal statute regulates this issue in the US, however, it does not stop individuals to continue their “job”. The same path is visible in the EU. Countries created laws, but they appeared to be ineffective.

To realize why odometers are the main “targets”, we need to answer the question – what does the odometer of an automobile measures? An odometer is a tool that measures miles and kilometers covered by a car. Even though altering an odometer is illegal, people still try to reset the mileage. According to the law, anyone who uses misleading odometers or artificially changes the numbers will face legal disputes.

How to prevent odometer fraudPreventing odometer fraud

Manipulation mileage is a common practice nowadays. Peoples with fraudulent purposes use different types of gadgets to fulfil their goals. what does the odometer of an automobile measure? It counts distance while a vehicle is moving. So, what does it mean? The short meaning is that you should pay more attention to the odometers and know how to detect clocking.

  • Tires – first of all, look at the exterior and the tires. It will give you an idea of what condition a car is in. Also, if the odometer indicates lower digits but the tires are too worn out, you can conclude that the information is not correct. In addition, manufacturers often add important details on their tires, so double-check that there is no mistake;
  • Wear and tear – a lot of owners claim that their vehicles are in the best condition, however good examination can reveal the truth. Make sure that the seats look new and do not forget to closely examine all the pedals. If pedals seem used, this means that they are not as new as the seller tries to prove.
  • Instrument cluster – what does an odometer of an automobile measure? It measures the distance. Hence, people usually try to replace an older odometer with a new object. Sometimes, they reset or delete existing numbers from the dashboard. It is very common to leave scratches during the process. So, look at the instrument cluster and if you see a lot of scratches around the odometer, make sure to stay away from that seller;
  • Damaged parts – when you are about to buy something new you do not expect it to have any damage. If you suspect that the original components were replaced, or see the damaged parts, you can assume that it can be a case of odometer fraud;

Therefore, what does the odometer of an automobile measures? It measures the distance traveled by auto. This is the main reason why individuals try to hack odometers and change the original numbers on them. You need to be careful and check all the details before buying a pre-owned vehicle.

Mileage Blocker – the best option on the market

A lot of companies tried to create a tool that would effectively change the mileage on the instrument cluster. People always wanted to roll back the miles displayed on the control panel. Once they succeeded, they would save money on their expenses and could make a bigger profit as well. Despite many attempts, all of them were unsuccessful unless they decided to manipulate odometers. But why odometers? what does the odometer of an automobile measure? It measures the distance travelled by automobile and then displays the numbers on the dashboard.

Recently, a young team from Germany has developed an innovative product – the Mileage Blocker. This device halts the distance recording process while a vehicle is in motion. It should be noted that this tool does not delete (that is illegal) any existing data from the system, it just stops counting up new miles. In addition, while all other similar products are traceable, the mileage blocker does not store any information in storage units and therefore they are completely untraceable. To make sure that the blocker works perfectly in any weather condition, it has premium-quality, heat-resistant components. Moreover, the official SKF product is the only one that has its mobile application. Hence, you can control everything from your phone.

Today everyone knows that mileage is important and that is why nowadays more people ask: what does an odometer of an automobile measure? The answer is the distance that a car has covered. The mileage blocker is an effective way to control odometer functioning. You have several different modules that you can choose from. So, it is up to you what percentage of the distance the system will record. Plus, it has easy installation instructions that save your time and budget. Fortunately, mileage blockers are available online and you can purchase one for yourself. Before you buy it, please notice that this device is only for car testing/tuning purposes and using them on freeways is unethical and illegal.

To conclude, many companies did their best to create tools that would manipulate odometers and successfully change the digits on the dashboard. The question is what does the odometer of an automobile measures that makes it so important? An odometer measures the distance covered by a vehicle while it is moving. The SKF team has successfully developed a mileage blocker that stops counting up new miles. Remember this device is only for testing and tuning purposes and nobody should use it on freeways. In case of any further questions do not hesitate to contact the official platform.


In this blog, we answered one of the most common questions: what does the odometer of an automobile measure? It measures the total distance travelled by automobile. Even though odometers are crucial components of any transport, people try to interfere with their normal functioning and adjust the correct numbers. The German team has created a Mileage Blocker that does not delete previous data. It simply stops counting up miles while a car is in motion. This tool is only for testing purposes and using it on public roads is illegal. For any additional information, please feel free to reach out.

 Potential odometer rollback is a common act of tampering with the vehicle that results in false odometer reading. As usual, the main goal of such tampering is to increase the sale price. Needless to say, it is a dishonest practice. Hiding real mileage for malicious purposes is illegal. Various organizations are fighting against it. For example, NHTSA creates campaigns to raise awareness in society. However, most parts depend on an individual’s effort. With a help of comprehensive information, we can protect ourselves and not let other people lie to us. What can we do? How to protect ourselves from this danger? – There are a variety of recommendations that will help you make decisions about taking measures to avoid becoming the victim. Before we move to the recommendations, let’s get to know what is “clocking”, who are victims of this crime, and what people use for such manipulation, how can we identify signs of such manipulation. 

Let’s get started and learn everything about potential odometer rollback.

What does potential odometer rollback mean? 

Also known as “busting miles” or “clocking” is an illegal practice of rolling back odometers to make them appear that it has lower mileage than it really has. It happened since the invention of odometers. In the past it happened manually with analog odometers, now digital odometers are tempered with a help of various devices that are sold freely online. 

Those tools are plugged into the car’s computer port, and people who aim to change the numbers can choose what they want their mileage to be. After resetting, automobiles display the numbers they choose. 

As for the analog odometer, you do not need special equipment. All you need to do is remove the panel and roll it back manually.

When we are talking about the possible clocking, it means that we suspect that the owner or dishonest dealer used some method to correct data for a deceitful purpose. You can employ various methods to find the hidden truth. 

You may think that it does not threaten you, but let me tell you that you can become a victim even without knowing it. Strictly speaking, it harms you not only financially but also can be dangerous for your life.

Look through the statistical data and judge the situation yourself. 

Who are potential victims and how are they identified? 

Potential targets and their identification

According to the NHTSA preliminary report, the problem is severe for American consumers, any vehicle on the used car market can be the object of tempering. Late-model Vehicles which accumulate high mileage in a short period are objects of tampering. Additionally, automobiles in business or rental fleets are victims of such manipulation. As long as the distance traveled is considered one of the key indicators of the condition and therefore the price.

Carfax is the leading vehicle history database. They report complete information about the accidents, maintenance, number of owners, odometer readings, emission inspection records, and other helpful information. They get comprehensive and truthful information from several sources such as Manufacturers U.S. motor vehicle agencies Auto auctions and salvage auctions, service/maintenance facilities insurance companies, car dealerships Import/export companies, Canadian motor vehicle records, and consumer protection agencies. As you can see, the list is long. Hence, it indicates how trustworthy the company is. The company marks an automobile with “Potential Odometer Rollback”, if two consecutive odometer readings are less than a year apart, the latter is a least 3 000 miles lower than the earlier one or 1 mile lower than the earlier.

The price of being a victim

As a buyer, you may put yourself in danger unconsciously. You may skip scheduled maintenance. Hence, it makes your transport less safe. 

You pay more than usual. As we mentioned above, distance traveled is one of the main indicators in determining the price.  

You need to report actual data to the insurance or financial company. If they discovered the truth before you, you may find yourself in an inconvenient situation. 

Signs of a possible odometer rollback

As we previously mentioned, some tips and tricks will help us to identify signs of odometer correction. It means you may not need a comprehensive investigation in order to guess that something is wrong. The identification happens differently, depending on the type of odometer. 

With mechanical odometers, physical signs of tampering are clearly visible. Scratch marks,  loose screws, messed up numbers on display, uneven spacing, unreadable numbers, and finally if you perform a test drive and numbers do not add up – all of that is an inevitable indication that it has been tampered with.

As for the digital one, the potential odometer rollback is not obvious. It’s harder to spot it. In this case, you need to inspect other parts and components such as steering wheels, driver’s seat, and brakes. If you have enough time it would be a good idea to inspect the auto completely and make your conclusions. If you are not confident in your abilities, you can ask for the help of an experienced professional who can say if the data is relevant to the general condition of wheels.  

How to detect genuine data? 

Detect the original data

We already talked about signs of rollback and tips to spot it effectively. Now let’s move to the particular measures to take in order to reveal potential odometer rollback. It should be noted that you can make conclusions yourself based on VIN checks, specific documents, or through visual inspection. Let’s discuss them one by one in more detail. 

Vin check

VIN is a 17-digit identification number for cars. It can reveal public information about automobiles such as features, specifications, and manufacturers. You can track registrations, warranty claims, emission ratings, and details like engine size, transmission, and fuel type. Additionally, you can learn whether it was stolen in the past or had a road accident. Needless to say, it provides you with mileage-related information at different periods.


Checking documentation closely is always a good idea when it comes to making purchase decisions. Documents always give you comprehensive information, it’s hard for others to lie to you when you take a closer look at details. You can compare data with what the seller says to you. Always ask for the original title. Do not trust copies, because dishonest sellers always try to forge those copies. 

Visual inspection

If you take a closer look at the steering wheel, pedals, seats, tires, pedals. You can estimate how worn out they are. With regular usage, from time to time the top layer wears off compared to other parts of the wheel.  If the seat adjustment mechanism is broken or not working, it’s a sign that it is not as new as the seller wants to show. If the pedals and driver’s side carpet look excessively worn, but the less km covered, the odometer has been tampered with.  


If you are not confident in your automotive skills, you better visit an experienced mechanic.  Mechanics have a better understanding of the internal condition of vehicles. They can guess easily if something is wrong. The most obvious indicator for potential odometer rollback can be when the seller refuses to allow a mechanic to perform a more detailed inspection. 

What do people use for “clocking”? 

People use different methods to mess with mileage-related data indicated on the odometer. In the past it was a manual job. “enthusiasts” remove the panel and changed data according to their wish. When it comes to the electronic odometer, there is a wide range of rollback tools that aims to decrease the numbers displayed. The biggest problem with those tools is that information is not removed from other control units, which means that anyone who takes a closer inspection discovers tampering. If you try those tools, you discover yourself in an inconvenient situation. In the worst-case scenario, you will face legal issues.

Apart from illegal tools, people start using the ethical tool called, Mileage blocker which is an extraordinary device for those who want to halt the kilometer recording process unconditionally. The purpose of halting this process may have ethical reasons such as testing the performance in a controlled environment. Installation is very easy, but if you come across any difficulty, our support team is ready to provide any service you may need. The most fascinating is that kilometers do not add up instantly even after removing the module. You can shop for it on our website. Unfortunately, wrongdoers benefit from the innovative possibilities of the module and use it for malicious purposes. 

At Super Kilometer filter We recommend not to use it for deceitful purposes. Committing odometer fraud is an illegal act that is strictly prohibited in the civilized world. 


So, you know the meaning behind the potential odometer rollback and also how to spot it like a pro. So, you know what to consider when it comes to the manipulation of odometers. On the other hand, as a buyer, you are armed with the knowledge that will guide you through the purchasing process. I guess you are well-informed of all the risks that are related to buying and selling automobiles. 

Bought a car with rolled back odometer? First of all, you need to know that selling or even using a vehicle with an altered odometer is strictly illegal and you have to report it. Different companies, garages and individuals always try to find a reliable mechanism to interfere with the correct functioning of the instrument cluster and artificially change the numbers displayed on a dashboard. To achieve their goal, they use numerous methods such as rolling back, stopping, freezing or deleting the mileage. These measures are getting massively used day by day and that is why you have to what to do in case you face the same issue.

As soon as you understand that the mileage was manipulated you should report it. you have several options to do so. You can call the police and thoroughly explain the situation you are in. They will tell you the exact steps to follow. You may also reach any law enforcement institutions for help. Authorized government institutions will guide you through the process accordingly. If knowing any, try contacting the person who has experience in working on such cases. He/she might have some useful tips for you. Moreover, officials will most probably ask you the details about the car, previous owners and documents. So, try to gather all the information in advance – this can be important and will save time as well. 

Hence, altering an odometer is against the law and the person responsible will face serious consequences. Please notice, that even if you had not done anything fraudulent but continued using it (while knowing about the problem), you may face criminal charges. Thus, in order to avoid further disputes and misunderstandings don’t hesitate to report the case right away and contact the appropriate departments.

Why is it illegal?

If you have Bought a car with rolled back odometer it is crucial to distinguish between legal and illegal practices. Every automobile has a special tool – an odometer that measures the distance. While you are driving the system counts up miles or kilometers and displays the numbers on a dashboard. To falsify the data people usually roll back numbers. In the past, they used to do it mechanically, however using modern technologies, the process is faster and easier on new cars with the digital instrument cluster. It can remove any number of miles in a split of seconds.

Any type of odometer manipulations which affect the normal functioning of the system is forbidden. In the United States, it is a federal felony and the statute controls it. Several states in the U.S. have regulations that stand above the statute in that specific area. According to the law, it is illegal to:

  • Disconnect, stop or alter an odometer;
  • Make conspiracies, and scams with other people regarding this topic;
  • Sell or use a vehicle with incorrect mileage;
  • Trade with a tool that causes the odometer to break down;
  • Advertise or sell such devices;
  • Accept incomplete or misleading official disclosure statements;
  • Forging official documents about the mileage.

If you break these rules the consequences will be serious. Depending on the country or the state you live in, a person faces a fine of nearly $10 000 or imprisonment for several years.

Furthermore, it is not a challenge that only the United States faces. Odometer Fraud is unlawful in most European countries. According to the European Parliament report, 15% of its population was a victim of such actions. Unfortunately, the EU does not have common regulations to fix it and illegal activities occur mostly in cross-border territories. In addition, tiny devices that are sold for only up to $200-300 can cause huge damage to the buyers who Bought a car with rolled back odometer. The US and the EU alone lose several dozen billion each year because of odometer fraud. 

Therefore, it is illegal to wound back the odometer in vehicles. According to the country, state or territory a person is located in, he/she will face different charges. Always follow the law and report the case immediately if you suspect odometer fraud.

How to avoid odometer fraud

Avoid odometer fraud

Even though adjusting mileage is punishable, people with fraudulent purposes are not afraid of it. The National Highway Traffic Safety Administration (NHTSA) released the data according to which around half a million purchased cars had misleading mileage in the United States. Due to this US citizens lose more than a billion every year. The same tendency is in Europe. The EU report illustrates that the estimated annual damage varies between €1.3 to €8.77 billion.

Companies all over the world are constantly developing existing technologies and trying to invent new ones. This is why new products appear on the market so often. Unfortunately, not all of these innovations are used in good faith. For instance, companies invented devices that freeze the mileage. People immediately started using it on a free highway which is unethical and unacceptable. Various types of devices are used to reset the mileage and it is essential to know what to look for when buying an old car.

The first step is to check the visual and physical appearance. Look at the tires closely. New cars do NOT have worn-out tires, so you will notice if there is anything suspicious with it. Plus, if the speedometer has scratches on the surfaces it can be the first sign of odometer fraud. Take a look at the pedals as well. Examine thoroughly to make sure that the appearance of a car matches the distance shown on the odometer.

If you want to avoid being cheated, like others who Bought a car with rolled back odometer, you need to make a deeper investigation. A pre-owned car is hard to control and sellers use it to their advantage. Request all official papers (such as service invoices, reports or log books) and compare the information to the odometer. You can check the details by using Carfax. Also double-check the oil change frequency and calculate approximately how long the auto has covered so far. You can find this information in a log book.

If you are still suspicious after a careful examination you can reach out to the professionals. They will check every detail for you and tell you in case there is anything wrong with it. Of course, this will not be for free, however, it is worth especially when you are going to buy something expensive. 

Why correct mileage is important?

Is correct mileage important?

Mileage has become an important aspect of our life. Every time we drive, we may check the distance we have covered. Why it is that important? There are several factors that make mileage important to us. 

First of all, it is the common view that lower miles mean better auto. People believe that if there are high numbers on the odometer it is older and needs more maintenance expenses. Simply, that is not true! The technologies have been developed so much lately that there are more important factors than mileage that you need to consider before buying a pre-owned car. For example, where and under what condition the owner used a vehicle. It does not mean that miles are not important at all, but their importance is mostly exaggerated.  The main reason is that they considered only the odometer showing and ignored other important details. 

Another factor that makes mileage important is private insurance companies. The insurance policies depend on the distance. This means that the lower the mileage is on the odometer, the less owner has to pay. Therefore, miles or km are directly in connection with the payments. To avoid additional expenses, people try altering the mileage. 

Rolling back odometers has become widely spread practice nowadays. Cars with lower distances have higher prices, and also need fewer expenses for an insurance policy. That is why more and more people try to somehow restore the data in the system.
