I have been getting 14.5mpg. I might as well be in a Ferrari with that kind of fuel consumption figure.

What does everyone else get :-) ?

I believe im getting 28-30 mpg in town and 40-42 mpg on the motorway.
On the motorway mine cruises at 75mph at 2500rpm. Its a 325i Convertible.

You've got to have a lot of faith to believe that.

They should return around 26 mpg average, with 30+ mpg achieveable on a long run/driven gently.

But in London traffic, you can expect low 20s or less.

That works out at 37.46 mpg. Probably about right on such a long run with a high ratio diff.

I would say about 26-27mpg average. I don't have an OBC, just watch the needle. So can't be too accurate.
