Regular maintenance directly impacts how much fuel your car uses. Keeping up with scheduled service can improve fuel economy by 3 to 10 percent, depending on your vehicle's condition.
Key Maintenance Tasks That Save Fuel
Oil Changes: Fresh oil reduces engine friction and improves efficiency. Stick to your manufacturer's recommended oil change schedule, typically every 5,000 to 7,500 miles for conventional oil or 7,500 to 10,000 miles for synthetic.
Tire Pressure: Under-inflated tires create more rolling resistance, forcing your engine to work harder. Check tire pressure monthly and inflate to the PSI listed on your driver's door jamb. Properly inflated tires can boost fuel economy by 3 percent.
Air Filter Replacement: A clogged air filter restricts airflow to the engine, reducing efficiency. Replace your engine air filter every 15,000 to 30,000 miles, or when it looks dirty.
Wheel Alignment: Misaligned wheels create drag and waste fuel. Have your alignment checked annually or if you notice uneven tire wear.
Spark Plugs: Worn spark plugs make your engine less efficient. Replace them according to your owner's manual, usually every 30,000 to 100,000 miles depending on the type.
Fuel Filter: A dirty fuel filter forces your fuel pump to work overtime. Replace it every 20,000 to 40,000 miles to maintain proper fuel flow.
Your Savings Add Up
Most vehicle owners spend about $1,950 per year on fuel for 15,000 miles of driving. Improving fuel efficiency through maintenance can cut that by $200 to $500 annually. That's real money back in your wallet.
