Today’s tip is in regards to several emails I have received about filling up your gas tank only quarter or half way.
Fill up your gas tank all the way each time you go to the gas station.
The logic behind filling up your tank only a quarter, half or three quarters of the way isn’t faulty – by putting less gas in your car you’re reducing the amount of weight your vehicle is carrying around, thus increasing gas mileage.
While the logic isn’t faulty, the practice of not filling up your gas tank all the way more than likely is.
By not filling up your gas tank all the way, naturally you will have to take more trips to the pump, needlessly wasting gas.
Additionally, every time you remove your gas cap to add fuel to the gas tank, vaporized gas escapes from your tank. As I stated in a previous Fuel Economy Tip, over 147 million gallons of vaporized gas escape from gas tanks each year, so the less often you remove your gas cap, the better.
So, I would say that at the very least, the amount of money you save by driving around less weight is negated by the money you’ll lose by making extra trips to the pump and vaporized gas you’ll lose each time you remove the gas cap.
