5 Things That Could Be Hurting Your Gas Mileage

Gasoline is becoming a more and more expensive expense for many Americans today. This makes our fuel mileage something that we need to be more cautious of. If you've noticed that your vehicle is drinking up more gas than usual, it may be more than just miles it is going. Some mechanical problems can bring down your mileage by as much as 30%. 

Here are some common car issues that can cause your vehicle's MPG to decline:

Low Tire Pressure

If your wheels are underinflated, your car is going to require more energy to move you from point a to point b. Make sure you always fill up your tires according to the factory-recommended PSI to get the best possible MPG.

Malfunctioning Sensors

Things like oxygen sensors or mass air flow sensors have a huge role in the combustion process. When they become impaired, it can cause your car to take in more fuel than needed. 

Dirty Air Filter

If it has been a hot minute since you last changed your air filters, it may be the cause of your poor fuel economy. A clogged filter can strain your engine, making it work harder to carry out its processes.

Old Spark Plugs

Spark plugs are another key component in ensuring a smooth combustion process. If your engine is misfiring along with your drop-in mileage, your spark plugs are likely the culprit.

Clogged or Dirty Fuel Injector 

A dirty fuel injector can accidentally spritz out too little or too much fuel into the engine. This can alter your vehicle's MPG as well.

 

If you suspect you have one of the problems above, please do not hesitate to bring your car to Rainier Automotive for repairs. Our team can help you restore your MPG back to what it used to be. Feel free to give us a call or schedule an appointment online with us today.
