Mine will do about 400/425 miles to a tank on a good run,I think that equates to about 29/30 mpg,but if your foot is of the heavy type which mine has been know to be Ive seen it drop to 15/18 :oops: :oops:
And here is a little tip,you can get about 50,000/60,000 miles from a fuel filter before it effects performance i.e superb mpg but crap exceleration :oops: :oops: :oops: :oops:
