If you have a car, one of the most important things you need to monitor is its fuel efficiency. Learning how to check your car’s mileage can help you save money on fuel, and also help you spot any potential engine or maintenance issues before they become expensive repairs.
Many drivers trust the mileage displayed by the car’s own computer, but it is not always the most accurate. That’s why experts recommend the tank-to-tank method, one of the most reliable ways to estimate real-world fuel economy.
In this guide you will find out how to get the most accurate reading of your car’s mileage, learn what affects fuel economy and useful tips to boost your car’s performance.
What’s the point of checking your car’s mileage?
It’s important to know how to check your car’s mileage for a number of reasons.
It enables you to:
- Keep a log of your vehicle’s fuel economy.
- Early detection of engine or mechanical problems.
- Plan your fuel.
- Service after performance. Compare.
- Enhance the resale value of your car.
- Reduce unnecessary fuel costs.
Regular mileages checks will also tell you if your car is running as it should be.
The Most Accurate Way: Tank-to-Tank Calculation
Experts say the tank-to-tank method is the most reliable way to determine fuel efficiency.
Work these steps carefully.
Step One: Fill Up The Gas Tank
Go to a fuel station and fill your car’s tank to the max. Try and stay with the same fuel pump as much as possible for consistency.
Step 2: Reset the trip odometer.
After refuelling, reset the trip meter of your vehicle to 0 km.
If you don’t have a trip meter on your car, write down the odometer reading.
Step 3: Drive Normally
Drive your car as you normally would.
Do not change your driving style just for better mileage as this may give inaccurate results.
Step 4: Fill up the Tank
If you run low on fuel, return to the same fuel station and fill your tank to the top.
Record how many liters you needed to fill up the tank.
Step 5: work out the mileage
Then use the following formulas:
Mileage = Total distance travelled / Fuel used
For instance:
- Distance covered = 520 km
- Fuel filled = 40 L.
Mileage = 520/40 = 13km/l
How to check your car’s mileage – this is the most accurate answer.
Why does dashboard mileage vary?
Most modern cars show fuel efficiency on the instrument cluster.
However, these readings can fluctuate depending on the sensors and driving conditions.
