The way fuel is getting expensive each passing day, it becomes much more important to keep track of your bike’s or vehicle’s fuel consumption. The mileage of a bike is one of the main concern while investing in a bike. It’s recommended to at least monthly check your bikes mileage or how much fuel it is consuming.

When your bike’s fuel consumption increases, there can be some issues with your motorcycle and some may be quite bigger issues such a defective spark plugs or clogged fuel. The reason could also be your riding, braking or aggressive throttling style. Now whatever be the reason, calculating the mileage of your bike is one of the good things to do and there are multiple ways to do that. We have picked up 3 ways to figure your bike’s mileage with simple formulae and also the measure of accuracy you may get with it.

The very basic formula of calculating mileage in KMPL is Distance travelled in Kms / Amount of fuel used in litres.

For example, if you ride your bike for 100 km with 5 litres of fuel, the mileage of your bike is 100km/5 litre i.e, 20 km per litre.

Now, we will use this same formula with 3 different setups.

how to calculate bike mileage

Full Tank Method

In this first method, you need to fill the bike’s fuel tank to its full capacity and reset the trip meter to 0. Now ride your bike for 100 km and again refill the tank. Repeat this process 2-3 times and note the amount of fuel filled in litres every time increase fuel efficiency of bike. Now, apply the above formula (100/ltrs) to each fuel notation and calculate the respective mileage.

You may find a difference in these notations and their average will give you a fair idea of the bike’s mileage. This method is the most common method to determine the bike’s mileage but it does not give accurate results as determining whether the tank is completely full or not is not surely confirmed (as air pocket often get formed in your fuel tank while filling).

Mileage Testing Bottle Method

This method uses a mileage measuring bottle that is directly attached to the carburetor hanging through the handlebar or taped to the fuel tank.

Here, the fuel pipe to the carburettor is attached with the measuring bottle with fuel (say 500 ml) in it and the trip meter is set to 0 and how to get good mileage in bikes is made to run until the fuel in this bottle reaches 100 ml.

Reserve Filling Method

This method involves the reserve switch or reserve digital indication of your fuel tank when the fuel is about to reach its reserve notation. As soon as your bike turns into a reserve position, reset the trip meter to 0 or mark the odometer reading.

Let us assume the odometer reading at this point is 2000 Km. Now at this point, fill the tank with, say, 1 litre of fuel (pre-filled bottle). Ride your bike till it again comes to the reserve position. Let us say at this point, the bike has covered 2050 km. Calculate the difference between the final and initial odometer reading which here comes out to be 50 (2050 - 2000) km. This 50 km is covered in 1 litre of fuel. Hence the mileage here comes out to be 50km/litre.
