I had a 2.8td diesel in my currant truck, this 35mpg on a long run (75mph). UK figures mind. If I work it out that's 29mpg with your size gallons.

The 3.1td that is in now gives more like 20mpg (16mpg to you) if I'm lucky <img src="/forums/images/graemlins/angry.gif" alt="" />

These two engines share the same block but the boor mpg of the 3.1 is due to it being indirect injection whereas the 2.8 is direct injection.

These are figures with stock tyres. With my mud tyres I am lucky to get 16mpg (13mph to you).
