Filling Up Your Tank at the Right Time

For summer, it is best to wait until you have a quarter tank, but don't push this any further. Doing this can extend your gas because you are hauling a lighter fuel load. It also gives you the opportunity to buy more gas if you run across a bargain.

Do the same thing in cold weather, and you run an increased risk of condensation in the fuel tank. Running a car with less than a quarter tank can shorten the life of the electric fuel pump and running on empty will often destroy the pump.
