    usually costs £45 to fill it, and for that i get around 280-300 miles, but 180 of them will be motorway and steady at 85mph. round town its pretty **** .. very low 20's...

    this 3mpg difference was the readings what i get from the display on motorway, i thought it a pretty good improvement for just tyre pressure..

    You can't get an accurate MPG reading like that. You need to fill it up to the first pump-cutoff, and reset the trip to zero. Then do a representative spread of normal driving until the tank is nearly empty (say when the low fuel warning light comes on), then go back to the same pump & refill to exactly the same point as last time.

    Then, divide the number of litres bought by 4.54 to get the figure in gallons. Then, divide the mileage reading on the trip by by the number of gallons used. Hey presto, an accurate fuel consumption reading.

    Fine, that takes care fo the arithmetic, but you still need to brim the tank accurately twice, to get a proper reading.

    I measure every tank of my 1.8T, careful driving (work driving) I get about 400 - 450 miles from a tank, weather dependant.

    Driven hard I get about 265.

    Do any of you use the mpg calculator on the DIS?

    I look at the DIS, but I calculate every tank manually.

    well im not lucky enough to have dis, allthough i dont think i would look at it much. gotta keep eyes on the road and my boost gauge 15 psi> 14 psi >13 change gear. ha ha no wonder my mpg is so bad. =)
