Common Problems that Affect Fuel Efficiency


Common Problems that Affect Fuel EfficiencyWith ever increasing gas prices it is important to do all that you can to get the most out of each fill up. By providing your car with routine maintenance you can maximize its miles per gallon, taking you as far as possible for your dollar. However, in between maintenance trips you need to pay attention to how your car is performing. If you notice you're spending more time and money at the pump, it could be due to one of these common MPG-lowering problems.

Low Tire Pressure

If one or more of your vehicle's tires are low on air it can drastically reduce fuel efficiency. The soft rubber takes more engine power to turn, meaning you're wasting fuel. Additionally, low tire pressure can result in increased tire wear, affect steering control and lead to a blowout. Regularly checking your tire pressure can help promote maximum safety and efficiency.

Overdue for an Oil Change

Completing oil changes on time as required by your make and model can maximize fuel efficiency. As oil ages and collects contaminants inside the motor it can turn to sludge, which means it is no longer properly lubricating the moving parts of the engine. This requires the motor to work harder, and with greater friction, which increases the chances of major engine trouble.

Clogged Air Filter

Your car runs on a mixture of air and gas, and if not enough air can get inside the engine due to a clogged air filter, your vehicle will compensate by burning additional gasoline. This is called running rich and can reduce MPGs by 25 percent or more.

Dirty Fuel Filter

You may think that if your car can't get enough gas to the engine then it will save gas, but the opposite is actually true. A clogged fuel filter will cause your car to run extremely poorly, causing it to misfire, if it can fire at all.

Malfunctioning Sensors

There are a few sensors in your vehicle that help dictate the air and fuel mix. These are the mass air flow sensor and the oxygen sensor. If either are unable to do their respective jobs they could cause the car to burn more gasoline than necessary. More than likely an issue such as this will trigger the check engine light.
