Empty Gas Tank? Why It's Bad for Your Car and Your Wallet

Do you ever run your gas tank close to empty before refilling? While it may seem like a harmless habit, running on an empty tank can cause some serious problems for both your car and your wallet. Here's why:

Damages Your Fuel Pump

Your fuel pump is accountable for pumping gas from the tank to the engine. When your gas tank is low, the fuel pump has to work harder to deliver the gas to the engine. Over time, this added strain can cause your fuel pump to wear out and eventually fail, resulting in pricey repairs.

Increases the Risk of Fuel Line Damage

When you're running low on gas, air can get trapped in the fuel lines. This can cause the fuel pump to overheat and create a dangerous situation. Additionally, low fuel levels can cause debris to build up in the fuel filter, leading to problems.

Reduces Fuel Efficiency

Running on an empty tank can actually reduce your car's fuel efficiency. This is because the fuel pump has to work harder to deliver gas to the engine, which uses more fuel. As a result, you may have to make more frequent trips to the gas station and higher fuel costs.

Leaves You Stranded

Perhaps the most obvious problem with running on an empty tank is the risk of running out of gas. If you're driving in an unfamiliar area or late at night, this can be a dangerous situation. It can also result in the need for a costly tow truck to get your car to the nearest gas station.

At our auto repair shop, we recommend keeping your gas tank at least a quarter full at all times. This will ensure that your fuel pump and fuel lines remain in good condition and that you don't run out of gas unexpectedly. If you notice any issues with your fuel system or fuel efficiency, turn to Portland Automotive for maintenance and repairs. With proper care, you can keep your car running smoothly and avoid unnecessary repairs down the line.
