Probably the same as with brands hatch. From my experience the fuel consumption doesn't change that much. Of course you have tracks with more full fuel parts but it's not that big of a difference.Has anyone in a 911 already worked out the fuel required? I'm most probably not going to get on until qualifying is well underway and I was struggling to put in clean laps when I practiced earlier this week, so I'm not sure I'll even be able to do the 2 laps to get the fuel calc to kick in.
Anyway, ACRL fuel shows you the range in minutes and I used 2x 50L for Brands Hatch in the Porsche.
So with 110L you should be safe and a few kg don't hurt imo.
I've set new PB's during races with 50% wear on the tyres and 40L of fuel compared to qualy with 0% wear and 10L...
