Do you ever have that experience when you know that your fuel level is low, and then the little light comes on telling you to fill up, but you’re all like, “well, I know I have enough to get to where I’m going… I’ll just fill up later”? Well, consider this blog us telling you not to do that. You should, realistically never let your tank get below a quarter full – here’s why!
The first reason is that your fuel gauge is not always accurate. Sure, there are some vehicles out there that will say cheerful things like “you have 5 miles until empty,” but even that’s not completely true. You never know how much is really left once you hit that E until your vehicle physically runs out of gas. It could be 5 miles, it could be 50, but do you really want to find out? There are plenty of videos on YouTube of other people testing it out. Just watch them, don’t try it yourself.
Next, your fuel pump uses the gas it pulls in as a coolant. When there’s not enough gas, it starts sucking in air. The air creates more friction and definitely isn’t as cool as the liquid fuel, and your pump burns out very quickly, especially if this practice is repeated often. The repair or replacement is expensive. Much more expensive than a tank of gas. Believe us, because we do that kind of work and we know that a tank of gas is much less expensive.
The final thing is that there’s sediment at the bottom of every fuel tank. When your fuel level gets lower and lower, that sediment gets closer and closer to getting sucked up with the fuel and pushed through your fuel lines and fuel injectors, clogging them up and destroying your fuel system from the inside out. If you let this happen often enough, your vehicle will need a full flush. That’s pretty dang expensive.
