9 Tips To Improve Your Vehicle's Fuel Economy

Tribune Newspapers

With the price of regular unleaded gasoline nearing $4 a gallon, auto information websites TrueCar.com and AutoMD.com have come out with a simple guide to getting more mileage from your vehicle.



Slow down: Most vehicles get the best fuel efficiency at 45 to 55 miles per hour. Driving more than 60 mph can cut fuel efficiency 7 percent to 23 percent.








Replace the spark plugs: Misfiring spark plugs can reduce fuel efficiency as much as 30 percent.



Change the oil:

Energy-conserving or synthetic motor oil can reduce engine friction, improving efficiency as much as 2 percent.


Remove excess weight: An extra 100 pounds in the trunk or back seat can reduce fuel economy as much as 2 percent.


7 Replace or tighten the gas cap: Fuel evaporates through gas caps with broken or weak seals, potentially reducing your car’s mileage 2 percent.






Keep the tires inflated: Tires that are improperly inflated have a higher rolling resistance, which reduces efficiency.

Keeping tires at the proper pressure can improve gas mileage as much as 3.3 percent.
