1.  Simply follow the maintenance recommendations in your owner’s manual. An out-of-tune engine can increase emissions and fuel consumption by as much as 15 percent. Always follow the manufacturer’s suggested tune-up schedule to ensure your vehicle is performing at its best.

2.  Upgrade your motor oil. Some of the newer high-performance synthetic motor oils have been proven to significantly reduce emissions.

3.  Regularly replace the air filter.  A clogged air filter can increase fuel consumption by as much as 10 percent. Air filters keep impurities from damaging the interior of the engine, so replacing dirty filters will save gas and protect your engine.

4.  Keep the tires of your vehicle properly inflated. The U.S. Energy Department reports that under-inflated tires can increase fuel consumption by up to 6 percent. One study estimates that 50 to 80 percent of the tires rolling on U.S. roads are under inflated. Astonishingly, we could save up to 2 billion gallons of gas each year simply by properly inflating our tires. 

5.  Avoid topping off your tank. Topping off releases gas fumes into the air and cancels the benefits of the pump’s anti-pollution devices. Capping your tank once the pump automatically shuts off is safer and reduces pollution. www.epa.gov.
