Two weeks ago, Managed to get 396 miles from 38 Litres of Diesel. This equates to 47.3 MPG over the week. Had to try my best not to ever use the right foot, which was impossible. I would say half the miles were at 70-80 MPH on motorway journeys then the other half average A-road speeds.
Last week, Decided to drive as I fancied and managed 328 miles to 34 litres of fuel, this equates to 43.5 MPG. Same journeys, just no speed restrictions.
Happy with anything over 40 MPG, as all my past petrol turbo cars with the same power, but much less torque have all struggled to give me more then 28 MPG.
So overall I must be driving with a slight lead foot, but good to know if required I could get well over 400 to a tank.
