4.5l per gallon, it's not too hard to work out if your brain works (mine doesn't so it took me a while :-P).
Mine gets 42mpg - usual for mine (1.9l berlingo, 2001) is 40mpg. I was quite surprised by that as it seems to burn through the stuff like paper!
Mind you, mine's getting 0mpg at the moment as it's died a horrible death, just waiting for the garage to come and collect to diagnose but it may well be terminal.
If it is I'll be on the lookout for something similar sized with same or better mpg (if there is such a thing).
