If you’re anything like me, you have a habit of topping off your gas tank when you stop at the pump. Like, if it ends on $20.32, I’m gonna try to get it up to $20.50 or an even $21. You might not think that there’s any harm in it, but you shouldn’t be topping off your gas tank after all. It’s a hard habit to break, but I’m working on it. Check out why this is a bad practice below!

So, first, it can overwhelm your evaporative system and break something or even cause a leak because of built up pressure. If your gas tank is too full, the pressure builds past the safe level when the gas heats up as your car moves. If there’s excess fuel, that gets sent to the evaporation system, and if you make a habit of overfilling your engine, you cut the life of that system way short.

Another thing is that it is actually a waste of money! Gas stations nowadays have systems where if too much fuel is going into your car, it just goes right back up the hose and back into the station’s tank. This means that you’re spending money on gas that’s not even going into your car.

Save money, save your engine – don’t top up!
