fuel gauge

Do not think I am getting around 250/300 miles per full tank, I think I am getting alot less than that but it is hard to tell as I am not sure about the gauge or unless there is a fuel problem??? using too much?? have checked the tyres andd they are at the correct pressure any thing else I can check??? As it is begining to cost alot of money just to drive 15 miles per day.

Yours sounds perfectly normal to me. Also in my experience it depends whether the car has been running for some time. Put the car away with about 1/4 of fuel, and start next morning and it's touching the red. After about 10 miles the gauge is warming up, but by then of course you have used more fuel anyway. I just treat anything from 1/4 less as a warning to fill up fairly soon.

A 240 auto is not the most economical means to cover 15 miles, though very stylish.
