Mpg?

That seems to work out at about 18mpg, not great, are the tyre pressures ok, and brakes not binding at all.

A more accurate measure for mpg is brimming the tank and recording the mileage, then when it needs another fill, brim it again and record the mileage that'll give a better overall figure.

I've seen mpg like that when I had a faulty pre cat lambda sensor. But, that would throw out a code.
