Thanks for that info gentlemen.
I think I've been seduced by many years of 40+ Diesel consumption numbers.
I used to get about 37 - 38 mpg out of my 160bhp 2 Litre Zetec 4/4 and I did think I would be getting a bit above 30 from the 3 Litre, 220 bhp Roadster.
It doesn't bother me but as some have said, fuel consumption can be a good indicator of how well an engine is running.
I will re-calibrate my brain to 30 mpg although westgardronning appears to be getting between 32 & 39 mpg if my conversion is correct.
