How To Change Mileage On Car? – Everything You Need To Know

September 7, 2021

Is it important to learn how to change mileage on car? Who would even need that information? – I’m sure you have these questions. The truth is – answering them won’t change the world. But that information will help you a lot if you ever decide to buy a used car.

Knowing how to roll back digital odometer will help you understand what people do to rip you off. That way, you’ll easily discover fraud and avoid overpaying for something that costs way less in reality. Let’s begin this article and figure out if it’s possible to change the mileage and how.

What is an odometer?

The odometer is the part of your vehicle that counts and records mileage. You can usually find it on the instrument cluster in a car. It’s probably the most dreaded system for many, as it’s basically a ticking bomb. If the numbers on the display are too high, your car loses the chance of being sold (no, it won’t matter whether you know how to sell a used car or not). Even though there’s no way to answer how many miles are too much for a used car, it’s still an issue for buyers. That’s why people search for various ways of changing those numbers.

But not all odometers work the same. Back in the day, the whole car relied on analog parts, so the odometers were analog as well. In other words, they consisted of cogs that would turn as the mileage increased. The miles traveled by car were counted by tire rotations, which triggered the swiveling of the cogs. The information about the mileage was stored on the odometer only. Even though you can still find cars with analog odometers, they aren’t commonly used anymore.

Digital odometers are the same concept, as they are also responsible for counting mileage. They use computer chips instead of cogs and cables to count and record the information. Digital odometers usually have a display where you can easily read current mileage. Unlike their analog counterparts, these bad boys also record mileage in the control units. That’s exactly why they have made it so difficult to reverse the miles without a trace.

Digital odometers are evil foes for those who want to reduce mileage and sell their cars at a better price. But they are kind friends for everyone who doesn’t want to be ripped off. Therefore, the sellers and customers try to figure out how to roll back odometer and what is an odometer in general. That way, they either have the chance to commit fraud or possess the necessary information to spot deception.

How to roll back digital odometer?

First, we have to answer if it is possible to reverse miles on a car. When you drive an automobile, you cover miles, but you can’t go back and “undrive” or “undo” that distance. So, if you cover 10,000 miles, the vehicle will add that number to the original mileage and display it on your odometer. This is why people use various tools and methods to rewind mileage on their digital odometers. Winding back an analog odometer was a piece of cake. You didn’t even need tools. You could simply mess with the system and force it to show lower mileage. However, digital odometers complicate things. There are two major ways to roll back the digital odometer:

  1. Remove the circuit board (also known as the wiring board) and change the mileage on the odometer;
  2. Use rollback tools that connect to the system’s electronics and allow you to manipulate the odometer.

Certain tutorials will teach you how to change mileage on car manually. It’s possible to alter the mileage even without specific tools. However, that process is rather complicated and time-consuming. You might even damage your car if you don’t know what you’re doing. That’s what makes tools that adjust mileage-related information so popular.

What tools do people use to change mileage on car?

how do people change mileage on a car?

Odometer correction tools and mileage blockers are the main tools people use to adjust excessive mileage on their trip meters. These two can be associated with many different names. Nevertheless, their features and capabilities are quite different.

An odometer correction tool has different names, such as odometer adjustment tool, odometer changer/programmer, speedometer correction tool, and mileage correction tool. They are small tools that can roll back mileage. With its help, you can easily set the desired number on the trip meter. You’ll just have to install the software and find the model of your car in the interface. Ultimately, you will be able to reduce mileage. If you’re willing to figure out how to change odometer reading, this device could be the answer. However, it can’t alter the mileage in control units, meaning that its effects can easily be detected.

However, there’s always the other side of the coin. It’s unethical to reverse the mileage. If you wind back the odometer and then sell that car without disclosing relevant information, you might face serious fines or even legal charges. Of course, laws vary depending on countries and states, but generally, odometer tampering isn’t a legal activity.

Another device that people use commonly is the mileage blocker (km stopper). It is an innovative tool that stops recording the mileage. The blocker is only meant for testing purposes and is an ethical unit. However, people use its features to their advantage and activate it on the open road. Considering the fact that the performance of the mileage blocker is untraceable, it’s easy to understand why people buy the kilometer stopper so frequently. You can also purchase this module for ethical purposes and get unlimited support, including installation and communication with customer service representatives. 

If you’re wondering how to roll back miles on a car just to commit fraud, you should think again, my friend. But I understand there are other reasons for changing the odometer reading, too.

Why do people learn how to change odometer mileage?

The primary reason people want to know how to change mileage on a car is to artificially change the mileage and make the system display lower mileage. This helps them increase the vehicle’s resale value and make better profit. The owners of used cars usually roll back the numbers on the trip meter to crank up the price for the vehicle that has lost its value.

However, there are more ethical reasons for reducing odometer readings. If your odometer breaks and you get a second-hand one, you’ll need to match its numbers with the mileage of your car. But it always comes down to how you do it in situations like this. You’ll be fine if you ask a professional to match the mileage and notify all the relevant services. You’ll have to disclose that information to your future customers as well.

The same goes for the wrong tires as well. As you already know, mileage is counted according to the rotations and the size of the wheels. If the tires are too big or small, the mileage will be recorded inaccurately. This can cause discrepancies. Once again, it’s better to use professional services to display real mileage on the odometer. Full disclosure is necessary in this case as well.

There might be other personal reasons for changing the odometer reading, but none of them justify doing it yourself.


We have learned how to roll back digital odometer and which tools people use to reduce mileage. You also know that manipulating the odometer and changing the mileage is unethical. However, there are cases when it’s necessary to stop mileage recording. In this case, the mileage blocker from SKF is the best device, as it’s the only tool that can effectively stop the mileage recording process and doesn’t leave a trace. Remember, this device is meant for testing purposes only and shouldn’t be used on free roads.
