Does it put strain on the engine of a car to run with a low level in the gas tank?

Question

Is it hard on the engine to run when the gas gauge is below half or a quarter? If so how does that strain occur?

Answer 1

Just the opposite with less gas the engine is pulling less weight which = less strain on engine

Answer 2

No, it don't hurt the engine at all, But it is a strain on the fuel pump, it will make it work harder in turn shorten the life of it. It is always best to try and have at least 1/4 of a tank of gas or more. And remember if your vehicle has an external fuel filter its best to keep it replaced at least one time every two year or 24,000 miles, this will help relieve strain on the fuel pump as well.
Good Luck and GOD Bless,

Answer 3

There is not a strain on the engine itself by driving a vehicle with a low fuel level,however if your vehicle has a in the tank fuel pump (IF YOUR VEHICLE IS FUEL INJECTED IT HAS A IN THE TANK FUEL PUMP) running a low fuel level CAN AND DOES CONTRIBUTE TO YOUR FUEL PUMP DYING PREMATURELY as the in the tank fuel pump uses the fuel in the tank as a coolant and a lubricant and being that replacing the in the tank fuel pump involves removing the entire fuel tank from the vehicle (VERY LABOR INTENSIVE AND EXPENSIVE) and a average replacement in the tank fuel pump can cost upwards of $500.00 it just doesn't make sense to let your fuel level get below half a tank.Also when your fuel level gets low the pump sucks up all the junk that accumulates in the fuel tank as part of day to day use.

Answer 4

Actually there is less "strain" on the engine because the car is lighter without the extra weight of gas in the tank. Low levels of engine oil however can lead to low oil pressure and extra wear and strain on your engine that will ultimately lead to engine failure.

Answer 5

Not the engine, but the fuel pump.

on most cars, the electric fuel pump sits at the bottom of the gas tank. And the gasoline actually serves as the pump's coolant. So if you drive around with the needle on "E," you're allowing the fuel pump to run hotter than it should, and potentially shortening its life.

Answer 6

no and the whole thing about the fuel pump is crap. The fuel pump is at the bottom of your gas tank so it is always getting the same amount of fuel. your tank gets pressurized as you drive. Ever take of the gas cap and hear a hissing noise that is the pressure releasing from your tank. The only thing I can recommend is that you do not run your tank completely out.

Answer 7

it doesn't put a strain on the engine however, running a car with less than a quarter of a tank starts to pick up all the dirt and setiment in your gas tank....subsequently: your fuel injectors clog, gas line gets dirt in it, and your fuel system runs dirty....

Answer 8

Nope, I have worked on cars for years. the only problem you may encounter is sucking up debris in the bottom of the tank. If you run out , then you may have to prime the carb , or pump before continuing on your way . But as long as you never run out , you may have to replace you gas filter a bit more often until all the debris is out of the bottom of the tank.

Answer 9

One theory: If the fuel pump on the car was cooled by the fuel around it, then running it next to "E" causes it to work at a much higher operating temperature, thus shortening the life of the pump.

Answer 10

Definitely not. And you could get a small increase in mpg by carrying less fuel weight.

Most, if not all, cars have fuel pumps to supply the fuel at a specific pressure -- not gravity fed. Filters protect your carburetor or injectors from gunk in your tank...
