I had bigger jets in mine and was regularly seeing 15mpg

620kg isn't half bad I'd have thought. The SR2 seemed to hop and skip a lot. It gave me the impression it was too light for road use on certain stretches of road. Mind you, I was being lifted off the seat too, glad I had the harnesses on!
How many mpg can you get now? Have you tried to see just how economical it can be out of interest?
I don't know how accurate the info here is http://www.super7thheaven.co.uk/Sierra_R...fferential
It's comprehensive tho! It seems the diesel is 3.38 but it's also available on some other models.
