It sucks when you notice that your vehicle suddenly gets poor gas mileage than ever before. Usually, the numbers don't tell a lie. A significant drop in MPG is a huge indicator that something is wrong with your vehicle most of the time.
There are so many different vehicle problems resulting in poor fuel economy. Here are some of the most prevalent issues that we've seen at Endurance Auto Repair and Tire.
- Tires - As you may know, there's a lot of maintenance that comes with your tires. For example, underinflated tires can result in more rolling resistance, lowering your fuel economy. To ensure you are getting the best mileage with your tires, we advise you to monitor its inflation at least once a month. The slightest adjustment can shift your MPG drastically.
- Air filter - The air filter is made of pleated materials that block out pollen, dust, and other contaminants from entering the fuel system. A clogged air filter can restrict airflow to the engine, causing an inefficient combustion process. Please check on its condition periodically to ensure your air filter doesn't take a hit on your gas consumption.
- Check engine light - Your engine relies on various sensors to monitor fuel delivery, ignition timing, emission controls, and more. If a sensor reads an unusual problem, it will alert the engine's drivetrain computer to trigger the check engine light.
- Oxygen sensor - Out of all the sensors in your vehicle, the O2 sensor in the exhaust stream is one of the most important. It is responsible for monitoring the oxygen within the exhaust gases. If the oxygen sensor becomes defective, it can cause the fuel injectors to put excessive amounts of fuel into the engine.
