Using mileage discrepancy while selling a car is a well-known method to get the premium price. Even though such action might even lead to legal issues, some people are still willing to take a risk. When you know that all the other providers use the same trick to sell their automobiles, sometimes you don’t stand a chance to get familiar with the odometer discrepancy.

Mileage discrepancy vs odometer discrepancy

Mileage vs an odometer

Before describing the purpose of these terms, we must know what an odometer and a mileage stand for. An odometer is a tool that people use for measuring the distance traveled by a vehicle. It might be either mechanical (consisting of cogs that turn based on the wheel rotation) or digital (uses a chip to measure and display the mileage).

Most automobiles also come with a trip meter (trip odometer). It’s a gauge that can measure the mileage of a specific trip. For instance, if you wish to measure the actual distance between your house and work you can simply use this function to get precise results. Similarly, measuring the actual Miles Per Gallon (mpg) is much easier if you fill up your tank and count the distance traveled. When you fill the tank up again, you can calculate the mpg on your own.

Is mileage discrepancy the same as odometer discrepancy?

Selling a car with mileage discrepancy might seem a thing of the past but it happens on a daily basis. The seller can use it for earning more money out of the trading even nowadays. The mileage discrepancy refers to misrepresenting the mileage of the automobile. The odometer discrepancy has to emphasize the unreliability of the odometer tool in terms of counting and reading the mileage but in most cases, these two terms are used interchangeably.

Why do people care about mileage?

Would you buy a car if you knew that it is going to become useless after 1 year? Even if you got such a car as a gift, it is doubtful if you could make good use of it. Car manufacturers use the mileage to portray the life expectancy of the car. Therefore, people always use mileage as the major factor while determining the remaining lifespan of the automobile.

Even though it’s controversial whether Mileage truly reflects the car’s wellbeing or not, people tend to trust these digits more than anything else. Especially if you are loyal to your car’s manufacturer, you will find it hard to believe that there are more important factors to rely on. However, if you are a car geek you don’t have to care about an odometer discrepancy.

Is mileage truly important?

The short answer is No. The life expectancy of an automobile depends on multiple factors and mileage is not one of them. However, it does reflect the approximate condition of a car. Let’s take the example of car parts. They wear out after using it after a certain period and the mileage does reflect to some extent how long they are going to last. Although, it doesn’t take into account the driving habits, road condition, location, and many other factors that determine the longevity of automobile components.

The mileage indicates how many miles an average person is going to drive a car before it gets broken. However, it doesn’t take into account all the other factors that we have mentioned above and can be quite misleading. Those who are aware of this issue prefer to sell a car with mileage discrepancy. Especially if they took good care of their “best buddy” and would like to express this through mileage.

What causes an odometer discrepancy?

If you have noticed an odometer discrepancy you may wonder what can be the cause of it. You may be surprised to know that this term may refer to a condition that is not under your control.

Total mileage limit of the car

Have you noticed how many digits can be displayed on your mileage indicator? Sometimes the mileage discrepancy is caused because of the number of digits that can be displayed as the indication for the distance traveled. For instance, most of the cars have five-digit (99,999) or six-digit (999,999) odometers. If you exceed this limit your car will not be able to count the mileage after reaching the limit. If you sell a car with a mileage discrepancy that is caused by such unforeseen factors make sure to keep a record of the approximate distance that you travel. This is vital especially if you intend to sell a car as the new owner will most likely be interested in this seemingly useless indicator.

Usage of mileage correction tools

Probably the most common reason that you have heard about is using a speedometer calibration tool. Those who have above-average mileage per month are more willing to use such tools. They don’t mind selling a car with mileage discrepancy especially if they are sure that their car is in much better condition than other vehicles with the same mileage.

However, take into account that using such tools for unethical purposes is forbidden and might lead to serious charges depending on your country of residence. To make sure that you are on the safe side only use such modules in controlled environments. The odometer stopper tool has many other advantages as well and might come in handy only if used for ethical purposes.

Be aware that using mileage correction tools for deceiving others is a direct representation of Odometer discrepancy.

Why do people use mileage correction tools?

Even though the name of this tool might seem self-explanatory for some of you, it can serve multiple purposes. In general, correction tools are meant for dealing with the unpleasant digits displayed on the odometer. However, we will discuss the advantages of Mileage stopper Tools because of their unique features.

  • To test the performance of the vehicle

Not everyone wants to use the mileage correction tool to sell a car with a mileage discrepancy. Using a premium quality mileage stopper tool will allow you to test the performance of your car without recording unnecessary mileage. The odometer discrepancy might be caused by worn-out or different size tires.

Similarly, if you are a Do-it-Yourself guy, probably would like to test your car in a controlled environment. People find it essential to install mileage stopper tools in order to avoid recording extra mileage while accomplishing this task. However, you can only do so in a controlled environment.

  • To correct the misleading data on the odometer

Imagine how difficult selling a car with a mileage discrepancy would be. Many people face such difficulties when they are not aware of the perceived value of mileage beforehand. Simply, the unusual size of the tires might lead to a thousand extra miles per year. The mileage Blocker can help you to reduce the recorded mileage in order to make it in line with the true distance traveled.

  • To fight with stereotypical perception

Imagine the situation, you are selling a car and you notice that all the other car owners have an edge over you because of corrected mileage. In such a situation, you might be triggered to do the same thing in order to sell at an appropriate price. Similarly, understanding car care can radically improve the life expectancy of the vehicle. However, the mileage indicator may not show actual figures and mislead potential customers. To avoid such difficulties people find it essential to use such modules at a certain stage of car ownership.

As you may have guessed, using the Mileage Stopper Tool for another purpose than testing is illegal in most countries. It is not advisable to sell a car with mileage discrepancy as it is unethical. Even though it might seem reasonable for most people, there are those who would use this module for rollback purposes. To avoid an odometer discrepancy allegation, you can also try to explain to the potential buyers truthfully what they have to know about your car. Even though you might not be the most reliable source in such a case, it is still worth a try.

Is selling a car with mileage discrepancy legal?

In the majority of the countries, selling a car with mileage discrepancy is illegal. That is why most people tend to use mileage stopper tools instead of rollback devices as they are untraceable. This is a plug-and-play tool that can’t be traced even with the computer and is widely used to keep mileage at a reasonable level. However, as we have already mentioned this is not the purpose of the tool and it doesn’t have to be used for such purposes. Use the module if you would like to test your car, and it will portray the condition better than the mileage.

Is it possible to check the actual mileage?

There are many ways to check the real mileage of the car but in some cases, it is still impossible to trace any correction. Some of these methods might be used by insurance companies as they rely on mileage figures to charge you a premium. Here are the most reliable methods to determine an odometer discrepancy.

Check the full history of the car

Selling a car with a mileage discrepancy became quite common nowadays. Hence, it is vital to determine any flaws before buying a second-hand car. There are many websites that check the title and the background of your automobile via the VIN check, for instance, CarFax, CarVertical, etc. Simply enter the VIN code and you will get all the information you need. You will see if someone altered the mileage. You’ll also be able to check the history of previous crash damage, theft warning (when applicable), and outstanding finance.

This step might be the easiest but it is not a free service and you will have to pay for it. You may find websites that offer such services for free but as you may have already guessed they will not be accurate.

Look at the car’s MOT certificate

MOT certificate can tell you if the automobile met the minimum environmental and road safety standards. Similarly, the MOT certificate always contains mileage data and you can access it to check the reliability of the odometer figures. However, it doesn’t guarantee that an automobile is roadworthy.

Ask the owner to provide such documents and compare them year by year to look for abnormalities. Look for the reasons for the unusual decrease in mileage for the specific year to make sure the odometer reading is accurate. If the owner can’t/won’t provide an MOT certificate, you can always check online using the registration number. This step will not apply to you only if the country of origin of the car doesn’t require such a certificate.

Simply ask the questions

Even though it might seem controversial most of the car sellers will simply disclose all the information if asked properly. Ask them freely and you may find out that you can get all the information that you need. Similarly, if you are not dealing with an inborn liar you will notice if they cannot provide convincing responses.

If you are buying from a dealer, check the paperwork to make sure that no disclaimer allows them to deceive you. For instance, some dealers may state that the mileage is incorrect and if you don’t read the paperwork you may rely on misleading figures.

Check the service history

The service history provides information about any maintenance services provided to the car. Besides, they keep a record of the mileage of the car and you can check the reliability based on the dates of service center visits.

The main drawback of this method is its reliability. This data can be easily falsified in order to deceive new buyers. To make sure that the data is reliable you can call the garages and ask them for the information that you require.

Inspect the vehicle on your own

If you are a car enthusiast, you would have already noticed the main signs of high mileage. Even though the mileage doesn’t always reflect the condition of the car, it is sometimes noticeable on most of the parts of an automobile. Check the interior and the exterior of a car and look for wear and tear signs. For instance, the condition of the steering wheel, pedals, and switches will indicate the approximate age of the car. The same applies to car paint. The new painting might indicate that the owner attempted to cover major issues and repairs.

However, it is hard to make such assumptions as the life expectancy of each component will depend not only on mileage but also on maintenance and the brand of the car. Some makers are famous for their exceptional quality of the components and will most likely last much longer than any other parts of their competitors.

Have an explicit test drive

If you have such an option, don’t hesitate to take a car for a test drive. Faulty parts usually cause unusual noises that you’d easily notice during the test drive. Similarly, some components simply depend on mileage. If the car is too old, its parts might easily wear out and require repairs. If the owner is selling a car with a mileage discrepancy most likely he wouldn’t care about the maintenance either. Such action could expose an odometer discrepancy. In that case, it would be pointless to make such adjustments.  During regular maintenance, it’s not uncommon to check the odometer reading and record the results of the inspection. 

It would be best to drive another car of the same model to make the comparison. This will allow you to determine if there are some unusual flaws.

As you have seen there are multiple methods to determine the true mileage of the car. However, all this hard work might even be in vain if the owner used the mileage stopper module. If this tool caused the odometer discrepancy, it would be impossible to determine wrongful figures on the odometer. This is why we always advise our customers to avoid using our testing module for such purposes.


Using mileage discrepancy while selling a used car is quite common these days. You have to be cautious to avoid buying a car with an odometer discrepancy. There are many ways to determine whether the mileage of the car is misleading or not. However, some people tend to use the mileage stopper tool from Super Kilometer Filter to stop the mileage of their automobile to deceive others. The main function of this module is to use it for testing the performance of your “best buddy” and using it for fraudulent purposes is unacceptable.
