Thanks for the explanation Erik.
That explains why I keep misjudging the fuel consumption!!
I thought that the first figure was the consumption for the last lap and the figure in brackets was the consumption that I should be aiming for........ no wonder I was running out of fuel.
So, from what you indicate, there is no display that tells me if I have enough fuel to get to the end of the race??
It looks like I will have to do some lengthy runs in practice and work out my fuel requirements, just to be sure. Or rely on you guys for an accurate fuel load ?? lol
