4 reasons you should never run low on fuel


It has been observed that sometimes people drive their cars with very low fuel in the tank. This habit is very damaging to the car’s fuel components and even its engine. Some people say I know my car it would not stop even if the fuel light is on. Most of the people do not realize that running low on fuel can actually cost you more. 25% of drivers believe that they can cover up to 60 km, once the fuel light turns on.

The following are the reasons explained why you should never run low on fuel.

1- Effect on the fuel pump

The fuel pump carries the fuel from the tank to the engine. If there is no fuel in the tank, it means it has . If the fuel is low in the tank, then the fuel pump would suck air rather than petrol. If you have the latest car with the newest technology, still then you can face a problem if you are running low on fuel. Also, running low on fuel can put stress on the fuel pump causing it to wear out prematurely. This problem can be faced if you drive your car low on fuel continuously.

2- Settled particles in the fuel tank

dirty-fuel-tankThe fuel in Pakistan contains many contaminants such as water and dirt which settles in the bottom of the fuel tank. If you run low on fuel, there is a high probability that these settled particles would be sucked by the fuel pump carrying them to the engine. That means not only poor fuel economy, rough engine operations, as well as the danger of clogging up the injectors.

3- Inaccurate fuel gauge

The fuel gauge of the car could be inaccurate. This can happen to old as well as new cars. The needle hits E on the dial and you think you can easily do, let’s say, 80 km. But instead, you might completely run out of fuel after 20 km. So try not to take a chance especially if you have an older car.

4- Petrol pump problems in Pakistan

Petrol stations running out of petrol can also be a problem. Although it hasn’t happened in the recent past, but it was a frequent occurrence a few years ago. So you must have some backup in the fuel tank instead of taking a chance.

  1. Why can't you clean up the fuel tank of all rubbish in it?

  2. The old mazda 808 (whose owner manual I found in the book market of regal chown khi) had this procedure.

    in that manual fuel tank cleaning was a service procedure every 24 months. I recall reading that again in a mazda 323 owner manual and service manual too.

  3. Happen to know what changed? Why do the companies make no mention of it? I tried looking it up in Altis owner's manual but couldn't find jack..

  4. there is a huge fuel filter in EFI cars, its the plastic casing that surrounds the fuel pump.

    older EFI units, like honda had a coffee mug sized can (accords) - the civics had a small tea cup sized one, older toyotas used a cylindrical shaped one.

    there has always been a filter.

    I dont know - why they removed the fuel tank cleaning service from vehicles, I did find it in mazda axela (mazda 3) service manual that mentions such when using the cars in african and asian countries.

  5. a good practice is considered to refuel at 33% - and in chevy trucks its a learned mistake, so people refuel them at 50%.
