Why should I fill up with gas if I have ¼ tank left? I can go another 100 miles!
It’s a good habit to fill up when you’re down to ¼ tank! In many, if not most cars, the fuel pump is located inside the gas tank. The fuel pump pulls the gasoline from the tank and sends it to the engine. It generates heat when it operates and uses the gasoline in the tank to cool itself down. If it is completely submerged, it will be kept cooler than if it has little gasoline around it. Heat and friction are the biggest enemies of all things mechanical. Your fuel pump will last longer if it is kept cool.
