Besides our car's overall performance, vehicle owners all want to save as much money as possible at the gas pumps. If you think about it, there has to be a balance of both. When it comes to fuel economy, two factors come into play: the health of your vehicle and your personal driving habits. Here are ten different mechanical reasons why you may be getting poor gas mileage!
- Inadequate Tire Pressure - If your tires are underinflated (or overinflated), you will notice uneven tire wear. This can cause a reduction in fuel economy.
- Dirty Air Filter - If your air filter is clogged and dirty, the engine won't get enough pure air needed to burn the fuel efficiently.
- Faulty Oxygen Sensors - Speaking of clean air, most automobiles have various oxygen sensors to measure the air intake and emissions output. If it becomes defective, it can negatively impact your mpg.
- Old Spark Plugs - Your spark plugs provide a smooth combustion process in your engine. If they are misfiring at the wrong time or not working correctly, your fuel economy will take a hit.
- Bad Fuel System - A bad fuel injector or dirty fuel filter can drastically alter fuel flow in the engine.
- Air Conditioner - The more frequent and powerful you run your A/C, the more it will decrease your gas mileage. If possible, try to limit your usage only when you need it.
- Motor Oil - Using the wrong type of engine oil can disrupt the performance of your car. Please ensure you're using the right kind and getting your oil changed on time.
- Excessive Idling - While this is not a mechanical problem, letting your car idle for too long can cause it to guzzle up more fuel than you think. If it's more than 30 seconds to 1 minute, please turn your car off or put it in neutral unless you need the engine running.
