Drivers everywhere can benefit from better gas mileage. Aside from saving at the pump, a well-maintained vehicle can also save you money spent on a new model. If you’ve noticed a spike on your gas receipts, it may be time to replace parts in your car that affect fuel efficiency – your tires, spark plugs, air filter and mass air flow and oxygen sensors.

Tires – Check tire pressure at least once a month. Worn or underinflated tires reduce traction, affecting your vehicle’s handling capabilities.

Spark plugs – Help your engine run cleanly (and more efficiently) by replacing the spark plugs, which ignite air and fuel in the combustion chamber.

Air filter – Dirty air filters are most common in cars that are 10 years or older, so replace yours immediately if you’ve owned your vehicle for a long period of time.

Mass air flow sensor – A dirty sensor transmits inaccurate readings, causing issues with your transmission, ignition and fuel injection.

Oxygen sensor – Switch out this sensor when it gets dirty, too. Faulty readings lead to incorrect fuel injection levels. Auto experts recommend replacement when your car reaches 100,000 miles.
