Pushing The Limits

When it comes to performance vehicles like BMW and Mercedes, drivers like pushing limits – racing RPM, red-lining, and testing suspension and speeds. But there are some limits set for your car you shouldn’t test. If you’re the kind of driver that pushes the limit on all of your vehicle’s systems, like your fuel pump, you may be in for trouble.

Save yourself from future problems and visits to the shop by knowing when to draw the line on your gas tank.

Vehicles have fuel level warning lights to give you a warning before your car runs out of gas. It’s simply a buffer to remind you of how far you have until you have no other option but to fill up or walk home.

The gas light also serves as a red flag. It’s telling you you’ve crossed the line. According to most driver manuals, 1/2 tank should be considered low and 1/4 full is the time to top it off again. Not only will it prevent you from experiencing that small panic of not making it to the next stop, but your car’s fuel system will also see better life.

By letting your gas tank go lower than suggested, you are more likely to burn out your fuel pump. It’s an expensive price to pay and an inconvenience when you take it into the shop.

The mechanical parts of a fuel pump are lubricated by fuel which travel through the pump. When the fuel level is low, air is drawn into the pump. Similar to running an engine without oil, too much air can damage the fuel pump if it isn’t properly lubricated.

Debris is likely to sit at the bottom of a fuel tank but when the fuel level is low, the debris has a better chance of entering the pump and plugging the fuel filters which, in turn, damages the pump.

The flashing and dinging of the gas light should be your ultimate last warning, however it’s better to take precautions and fill up sooner rather than later. Pull over when you can and make it a priority to save you time and money by filling up.
