How to Fix Mileage Discrepancy

Have you ever gone to fill up your gas tank only to realize that your car’s mileage is way off from what the display said it would be? If so, you’re not alone. This is a common issue that can happen for a variety of reasons.

But don’t worry, there are ways to fix it! One thing that can cause this discrepancy is if your tires are low on air pressure. When this happens, your car has to work harder to move, which can use up more gas than usual.

Another possible culprit could be debris or build-up in your fuel line. Over time, this can restrict the flow of gas and lead to lower mileage.

  • Research the vehicle’s history to see if it has been in any accidents that could have caused damage to the odometer
  • Inspect the vehicle for any physical signs of tampering with the odometer
  • Compare the mileage on the vehicle with maintenance records and previous owners’ statements to get an idea of what is normal for that particular car
  • Have a certified mechanic inspect the vehicle to see if there are any mechanical issues that could be causing the discrepancy

How to Fix Mileage Discrepancy on Carfax

If you’re in the market for a used car, you’ve probably done your fair share of research. You may have even come across a few cars that you’re interested in, only to find out that there’s a discrepancy in the mileage reported on Carfax. But what does this mean?

And more importantly, how can you fix it? The first thing you need to understand is that Carfax relies on self-reported data. This means that if a dealership or private seller doesn’t report the accurate mileage to Carfax, it will show up as a discrepancy.

In most cases, this isn’t intentional; it’s simply an oversight. That being said, there are some instances where the discrepancy may be due to odometer fraud, which is when someone purposely rolls back the odometer to make the car appear to have less wear and tear (and therefore be worth more money). If you suspect that this is the case, you should report it to Carfax so they can investigate further.

So how do you fix a mileage discrepancy on Carfax? The best way is to get written documentation from the seller confirming the accurate mileage. This could be in the form of a bill of sale, maintenance records, or even a letter from the dealer stating that they mistakenly reported the wrong information.

Once you have this documentation, simply upload it to Carfax and they’ll update their records accordingly. While a mileage discrepancy might not seem like a big deal at first glance, it’s important to take care of it before moving forward with any purchase. By following these simple steps, you can rest assured knowing that you’re getting an accurate picture of the car’s history – and making sure that you don’t overpay for something that isn’t worth as much as advertised.

Why Does My Car Have a Mileage Discrepancy?

If you’ve ever noticed that your car’s odometer reading is different than what’s shown on your car’s maintenance records, you’re not alone. Many car owners have experienced this discrepancy, known as “mileage discrepancy.” There are a few possible explanations for why this may happen:

1. The most common reason is simply that the previous owner forgot to update the maintenance records when they got their oil changed or had other work done on the car. Over time, these small discrepancies can add up to a significant difference between the two readings. 2. Another possibility is that the odometer has been tampered with.

This is more common with older cars, but it can happen with newer models as well. If someone has intentionally changed the odometer reading, it’s likely because they’re trying to sell the car for more money than it’s actually worth (known as “odometer fraud”). 3. In some cases, there may be an issue with the way the odometer is calibrated.

If it’s not reading accurately, that could explain why there’s a discrepancy between the two readings. However, this is relatively rare and would likely be noticed by a mechanic during routine maintenance. Ultimately, if you notice a mileage discrepancy on your car, don’t panic!

It’s usually nothing serious and can easily be explained by one of the above reasons.

What If the Odometer Does Not Match the Title?

If you’re in the market for a used car, one of the first things you’ll want to do is check the odometer reading against the title to make sure they match. If they don’t, it could be a sign that the car has been “clocked” – which means someone has purposely reset the odometer to make the car appear to have less miles than it actually does. This is done in an attempt to sell the car for more money than it’s actually worth, and can be very difficult to spot if you’re not familiar with what to look for.

Here are a few things to keep in mind if you come across a clocked car: – The overall condition of the vehicle should not match up with the low mileage indicated on the odometer. For example, if the bodywork is scratched and dented or there are signs of wear and tear inside the cabin, it’s unlikely that the car has only travelled a few thousand miles.

What Happens If You Buy a Car With the Wrong Mileage?

If you purchase a car with the wrong mileage, it could lead to a number of consequences. For one, you may end up paying more for the car than it is actually worth. Additionally, if the car has been driven further than what is stated on the odometer, it could mean that there is more wear and tear on the vehicle than you were expecting.

This could lead to expensive repairs down the line. Finally, if you resell the car, you will have to disclose the incorrect mileage to potential buyers, which could significantly decrease the resale value of the vehicle.

How Do You Calculate Mileage Discrepancy?

There are a few different ways that you can calculate mileage discrepancy. The most common way is to use a GPS device or smartphone app to track your route and compare it to the odometer reading on your car. This method is generally considered to be the most accurate.

Another way to calculate mileage discrepancy is to use online mapping tools like Google Maps or MapQuest. You can enter in your starting point and destination, and the website will give you an estimated distance for your trip. Compare this number to the odometer reading on your car to see how much off the car’s readings are.

Finally, you can also estimate mileage discrepancy by simply keeping track of how many miles you drive in a day or week, and comparing that number to what your car’s odometer says you’ve driven over the same period of time. This method isn’t as accurate as using a GPS or online mapping tool, but it can still give you a general idea of how much your car’s odometer may be off.


If your car’s odometer reading is lower than what you expect, there are a few possible explanations. The most common cause of mileage discrepancy is simply that the car was driven less than you thought. Other causes could be that the odometer was reset at some point, or that the car has been in storage for awhile and the battery died, causing the odometer to reset.

If you think your car’s odometer may be inaccurate, there are a few things you can do to check and see if it needs to be fixed. First, compare your car’s current reading with past records – like oil change receipts or maintenance logs. If there’s a big difference, it’s possible that the odometer has been reset at some point.

You can also have a mechanic check the odometer while they’re doing other work on your car; they should be able to tell if it seems off. Finally, keep track of your car’s mileage going forward so you can spot any discrepancies right away.
