my car has a small engine (1600cc) and I dont care how many Mpg it does or doesn't do.

I just fill the tank when needed and drive away.
Why all this discussion on mpg?
if you drive it, fuel has to go in one end and out the other, (food for cars) so give a big sigh and GO WELL, GO SHELL (sic)

If you are doing nothing, how do you know when you are finished?
