When trying to fix my gas gauge, I checked between fill ups to see what kind of mileage I was getting. I was a little surprised to find I was getting about 7 miles to the gallon. It has not been tuned up or had much else done to the engine but it starts fine and runs well. I believe my engine is a replacement FE 390. But still I thought I would get maybe 12 miles per gallon at least. What kind of mileage did (do) these cars get?
