Horrendous mpg on the bosch?

I never have that much money lol :/

But you still put a tankful in......either in tenners, or all at once lol......whats the difference?

Just a quick way to work out rough mpg in your head; At 45mpg (which you should easily get from a dt!) the litres match the miles - so a tenner = 7 litres = 70 miles at 45mpg. If youre really only getting 30 odd miles then thats 22mpg.............
