Nollywood, how many litres do you usually need brim to brim?

I don't really observe how many litres. I just brim and that's it. When I first bought the car, I drove 19 miles with 0 range showing before my nerve broke. I had a 5 litre jerry in the trunk though, just in case.
So now, I know I can go 15 miles on 0 range, though I seldom do. Once 0 appears, I fill up. In emergency situations, when I can't find 98/99 RON fuel, I will drive on 0 range for up to 15 miles till I get the high octane stuff.
My '98 S8 achieved 426 miles consistently on a full tank, conversely my '96 4,2 QS consistently achieved a lot less - 390 miles. No error codes, regularly serviced, and I was the second owner. It had all the services bar three done at the supplying Audi dealership - Martins of Basinstoke. The other three were carried out by Colindale Audi.
This would suggest the 40V engines are more efficient - they are Euro III, some late ones Euro IV (not including early pre-FSI D3).
