How to calculate K.M/Liter/ Average consumption

[pwuser151471125463]

Recently, I purchased GLI-2010 and I want to calculate its average consumption. For this purpose I filled the tank Full. I asked the fuel pump official to fill the fuel tank of the car full. He asked me "Auto full krna hay ya top tak full ker dun?" I said him "Top tak full ker du". so he full the tank upto the top. Is this mean the car has 55 liters of fuel in it ? or in case of auto full the car has 55 liters?. Here I have little confusion. please guide in this regard.
In order to calculate
1) if suppose car is full of fuel upto 55 liters.
2) the car has driven 150 kms
3) I again re-fill the tank upto 55 liters (for e.g the car has already 45 liters available, (10 liters filled this time))
The per K.M average is : 150/10= 15 KM/Liter
Is this method correct for calculating the Per KM average???

Get it filled till autostop.
Drive
Then again get it refiled till autostop.
See how much litres it needed.
Divide the number of kms by litres.
Thats simple.

Method is correct.
Divide the KMs traveled by the amount of Fuel it took to refill the tank.

do you think autostop has full capacity of the tank i.e 55 liters?

[ibaloch777]

I think yes. It should not be topped up further.

Hi everyone,

Your method is spot-on: divide the kilometers driven (150 km) by the liters refilled (10 L) to get 15 km/L. Auto-stop is the way to go, as ibaloch777 suggested, since it ensures a consistent fill (usually close to the tank’s 55 L capacity for a Corolla). Topping up beyond auto-stop can vary due to air pockets or pump differences, which messes with accuracy.

For my own tracking, I use a kalkulatorpaliwa.com.pl to double-check consumption and plan trips, especially when testing different driving styles. It’s been handy for confirming km/L. A couple of questions:

Do you reset the trip odometer each time to track exact km? That’s helped me avoid errors.
Has anyone noticed better km/L with city vs. highway driving on the GLI-2010?
Would love to hear your tips for getting the most accurate fuel average!

Yes it does.
