Had the Dooper since Nov 07 and now covered 3000 miles. Used Shell Diesel since the dealers tankful was used.
Over the last 1000 miles the average consumption has been 57.6mpg.
Normal journey is 22 miles round trip, 6 miles is town, the remainder is B roads where the traffic moves at 50-55 mph.
Best so far is 72mpg on a 110 mile mostly motorway.
The car has 17 inch run flats, also have the auto a/c on 100% of the time set to 21 degrees.
If you are getting average consumption in the 30's, then there is something wrong with the car.
