We all know that gas prices fluctuate, and mostly not in our favor. Often we wait until prices go down or we get an empty signal from our vehicle to fill our tanks.
But is this actually the best thing to do for our vehicles?
Although it may be more convenient to wait for a price drop or it may seem better to use up the gas already paid for than to top off from gas already used. It is not always in the best interest of your vehicle.
You should always fill your gas tank to full as you essentially do not want to treat your vehicle as though it has a smaller tank then it actually does. Furthermore, do not wait until your tank is on empty prior to filling it up again. Once it hits half a tank, fill the vehicle again. “Why?” you may ask.
Here are 3 reasons to keep your gas tank full:
- Condensation – Condensation can form in the empty part of your gas tank. In the winter that condensation can freeze, collect into icy pieces that block your fuel lines and create problems with starting your car. The best way to avoid this happening is to keep your tank more than half full at all times.
- Dirt or rust in your tank – Along with condensation, dirt or rust can occasionally get trapped in your fuel tank. When you’re running low on gas, that sediment can collect and block your fuel filter, possibly leading to expensive repairs.
- Fuel pump failure – The motor of your electric fuel pump needs gasoline, which acts as a coolant, to operate properly. When your gas tank is getting low, the pump can suck in air, which generates heat. Over time, that heat buildup can cause your fuel pump to wear down or even fail altogether. Fuel pump repairs are expensive and can be prevented. You can prevent them by simply keeping your gas tank at a higher level.
Turning these tips into habits will not only prevent condensation from getting into your gas tank and thus costly fuel pump repairs, it will ensure that you are never stranded on the side of the road due to an empty tank. This way you keep money in your pocket when it comes to gas in your tank.
