Have to give the F12 another try...I used to have huge problems with the fuel consumption, could hardly manage to get 3 laps out of it on FM6-but that was a long time ago, my skills have increased since my last try with that car
Edit: I gave it a try, and while I did win, I still had massive coasting to do in order to make 3 laps with one tank...
First try: barely made 3 laps, some rain, but not enough for IMs...still some showers in laps 4 and 5...paid too much attention to the weather radar and run out of fuel in lap 5 right at the Porsche advertising...I was thinking FM2 will yield 2 laps, but id didn't...
So I quit...
Second try, same conditions...again 3 laps with one tank and massive coasting, then 2 laps with FM3(even some FM4 on the last quarter of the track), then another two laps...started with FM4, then on the final lap FM1 for the most part...caught up with the two leading cars on Mulsanne(Portilla and Haywood) and overtook them...switched back to FM4 when I entered the Porsche curves...enough for the win, last lap was the fastes with 4.09,something...(used RHs for the 3lapper, and RM for the 2lappers)
