Poor Gas Mileage? 5 Common Reasons Why

Gas is expensive, especially if your vehicle is a gas guzzler. If you aren’t driving more but are making more trips to the gas station, there may be a minor problem. A decrease in gas mileage can indicate your engine isn’t running as efficiently as it should. If you find yourself spending more money on fuel, you may want to have your vehicle inspected. Below are five aspects to check if your car is using more fuel than usual. 

Dirty Air Filter

The air filter ensures pollutants don’t enter the engine from the air sucked in while driving. Air filters can get pretty dirty over time due to a change in weather and road conditions. A clogged air filter will limit the amount of air that reaches the engine causing it to work harder to perform. 

Bad Oxygen Sensor

The oxygen sensor is vital because it maintains a proper mixture of fuel and air. The oxygen sensor typically needs to be replaced every 50,000 to 60,000 miles, but it can pose some serious problems if forgotten. If the oxygen sensor can’t balance the appropriate air and fuel intake, you may notice a massive hit to your gas mileage. 

Tire Pressure

Throughout the month, your tire pressure can fluctuate, making it essential to check them regularly. Tires that are over or under inflated can cause a decrease in fuel efficiency. Your vehicle’s recommended tire pressure can be found on the driver’s door plate. 

Fuel Injectors

The fuel injectors, true to their name, inject fuel into the engine. Fuel injectors can become dirty, leading to rough idling. Any impact to the fuel injectors will decrease the amount of fuel that enters the engine. Your engine will work harder to overcompensate for the lack of fuel, guzzling more gas.

Spark Plugs

The spark plugs help produces a mini-explosion or combustion in the engine. Worn spark plugs should be replaced because neglecting can leave you spending more at the gas station. In severe cases, worn spark plugs can cause the engine to misfire.
