Auto Maintenance for Better Gas Mileage
Proper maintenance on your car when needed is a tremendous gas saver. Tune your engine occasionally and keep your tires aligned and properly inflated at all times. These can improve gas mileage by about three percent.

Also, change the oil regularly. If possible, opt for the oil labeled “energy conserving” to increase gas mileage and reduce emissions. Replace the air filters on a regular basis to enjoy up to a ten percent gas mileage improvement.
