Save on Fuel Costs: Basic Car Maintenance
The US Department of Energy says maintaining your automobile can significantly improve performance and gas mileage, particularly with older vehicles.
The checklist includes keeping your engine properly tuned, regularly checking and replacing air filters, keeping your tires properly inflated, and using your car manufacturer's recommended motor oil.
Maintaining healthy air filters offers the most significant savings of up to 31 cents per gallon based on a sample fuel price of $3.10.

Comments
"Using your car manufacturer's recommended motor oil" sounds misleading. The article is actually recommending not using a *grade* of oil other than that recommended by the motor manufacturer.
