You can see how many laps are left with your current fuel when pressing an F-key.. I think it's F4, not sure anymore. It's the one where you can set how much to refuel at a pitstop. Just press through the F-keys and you should find the information in the black box on the lower right.

..and you might always ask in the specific car forum. Many times it's a set value used for all tracks on the schedule.. can't help with the V8 myself, sorry!

Keep in mind fuel consumption when you put fuel in the car is anything but precise...
It will tell you that you can do 30 laps with let's say 8 gallons... When you actually need 10 or 11 gallons to do these...
Don't believe what it says
Best is to do a practice run with a certain amount of laps and see exactly how much fuel you used... Or like me, ask everyone how much fuel you need for the race

Put in a couple of gallons of gas and run until you're out. Take those numbers, laps and gallons and get your ave.

I think its calculating it dynamic... do a few laps with fuel box open. It will start with to many laps but after the 2nd lap my numbers usually drop to the right level.

That's right, it's based on the current fuel consumption - forgot to put that into my reply. Thanks for the clarification.
