Why the Fuel Tank should be Half-Full


You have probably heard how important it is to keep the fuel tank fuel, and at the very least, keep it half full. While some people think they are saving money by letting it get as low as possible before filling it up, you may actually be doing more harm than you realize. It is important to keep the fuel tank filled up as much as you can. That way your vehicle will be ready to go if you should need it in an emergency situation. Also, if you happen to get lost where gas stations are infrequent, you will be able to drive further with a full tank of fuel.




The most important reason to keep the fuel tank up is for emergency situations. You are less likely to be stranded someplace due to a lack of fuel. Also, you can benefit from a full fuel tank if you happen to be stuck in traffic for a long period of time. If you need to travel in the middle of the night for an emergency for yourself or someone else, you can be reassured there is enough fuel to get you to your destination or a gas station that is open.


Prevent Condensation


If you run your fuel near empty consistently, you may find yourself having to have more vehicle repairs more often. The reason for this is because of condensation and evaporation. Every time you open the fuel tank, gas vapors escape. When the fuel tank is mostly empty, there is also a lot of free space to collect water. When the vehicle is run near empty, the fuel has more room to create condensation. If the condensation gets into the fuel lines when the temperatures are cold out, it could cause freezing in the lines.


Protect Fuel Pump


Since gas is lighter than water, the water will get closer to the fuel pump. If water goes through the fuel pump first, it can result in repair bills that could have been prevented. Also, it will make for a hard start for your vehicle and cause the starter to wear out sooner. Water will wear on the fuel pump because the water does not lubricate the fuel pump like the fuel does. The water can also cause damage to the fuel injectors over time and frequency. This will all result to a larger repair bill. Keeping the fuel tank at least half full, especially in the winter, is a great way to help your vehicle be as efficient and reliable as possible.
