Fuel in Strategy

Is it a bug or the way it is meant to be?

1 stop 175L 86 + 89
2 stop 174L 58 x 3
3 stop 175L 46 + 43 x 3
4 stop 176L 37 x 2 + 34 x 3

That is before any test runs, afterwards the fuel amount will be lower.

What are you trying to get at? I have no idea what you're asking about.

why less fuel used in 2 stops than any other, should they not all have the same amount of fuel overall?

It's because you can only fuel your car in intervals of 1 whole number, so obviously you're gonna get slightly different overall fuel levels, as the amount of fuel you need, after rounding up the fuel per stint, differs.

If 1 extra stop takes 1L extra then 1 stop should be the lowest fuel amount.

We need fuel the same as estimated laps then decimals

It's hardly fair in fuel econ department.
If my car uses 2.3 per lap and your car uses 2.2 per lap they are gonna be rounded off to the same number.

Oops 2.3 & 2.2 is a bad example in 3 lap race
2.2 will carry 7L and use 6.6
2.3 will carry 7L and use 6.9

I'd like to fuel cars down to the tenths and hundredths too. What you describe isn't a bug though, so I am moving it to the help & support forum.
