I just found out that even if the fuel is greyed, you can reduce it to 1lt. I'm afraid that all the recent competitions had the same bug. Guys, you have to fix this asap.
No you are wrong. FR US: INDIANAPOLIS,with default fuel, after 4,5 days: 1.10.482 FR US: INDIANAPOLIS,with 1L fuel, after 8 minutes:1.10.176 , another 15 min. 1.09.739 I'm sorry but the Thrustmaster and KTM competitions wasn't on equal terms.
The amount of fuel changes in the car, but I do not know if it has any effect on physics. Edit: Tested in Macao-KTM Competition
Yep, I can confirm that. The car feels lighter, braking points are later and more speed on the straights. Improved my time on Nürburgring VLN by 1sec to 7:58.
