hi, is it an 8v or 16v?
I'll give quoted figures and what I think are realistic for both:
8v 38mpg, achievable on motorway, realistically 34-36mpg? maybe less in town.
16v 32mpg, achievable on motorway, in town I get 28mpg. On average calc on mileage and full tank works out about between 28 and 30mpg.
