i dont have a trip computer but i know somethings up with the car because dont think i should only be getting 260-270 miles to a full tank, anyone care to work out how many mpg that is?
Driving at 135 will usually give better mpg then some garage chav taken it for a 'test drive' because at 135 your covering distance so quick and so better "miles" per gallon, rather then flying up and down the revs stop start etc lol Strange that really lol
my best is 51mpg, average speed 57mph. But it's boring.
and justin....135mph will be pretty much at peak horse power, therefore using more power, which is energy over time.
stopping and starting, revving up and down, hitting peak power less often would surely be more economical.
Its not at the lights its just I tend to use 4th on the A1.
More power that way.
