Hi welcome. First off, you have to go on EDIT VEHICLE, you can then select litres to fuel up. Now depending on if you're using the odometer reading, or the trip meter on your dash, there are two different methods to track fuel consumption. If you use the trip meter, then ignore any current miles on the odometer, just fill the tank and reset your trip meter, next time you fill up, you'll know how much fuel youve used and how many miles youve done. Get it?
