I am assuming you ain't driving it very hard to get 33mpg?



Put it this way... he ain't slow.


All the miles to a tank talk is next to meaningless though unless the tank is filled to the same point by everyone and then driven until it runs out.
The last 20-30 miles out of a tank will make a massive difference to the overall apparent economy figure.

It is better to:
1) Fill to the brim (to the filler neck)
2) Reset the trip mileage
3) Drive until whenever you next feel like filling up
4) Fill the tank to the brim
5) Calculate the economy from the mileage and number of litres inserted.

33mpg is pretty impressive I think. Even after a decent 110mph+ stint (private road ) in my Mondeo I am still averaging 46.8mpg to the tank.
