Products that increase gas mileage improve the quality of driving. Many products increase the number of operation miles before a car requires replacement. According to the U.S. Department of Energy, utilizing some basic products, drivers can improve gas mileage to save money, reduce carbon emissions and improve the quality of car engines.
Not only does correct auto air tire pressure improve driving safety, it reduces the amount of gasoline cars use. For most vehicles, there is a tire pressure chart located on the driver's door or in the car's maintenance manual. Some vehicles have a low-air warning if one or more tires fall below recommended pressure levels. According to the U.S. Depart of Energy, low-air-pressure in tires results in decreased gas mileage. Check tires with each addition of gas to make certain air-pressure levels are the appropriate amounts.
Motor oil helps to reduce friction in the car's engine. Each engine requires a certain weight and type of oil. The first number on the can is the type of oil. The second is the weight. The car's operator manual details the recommended oil for that particular vehicle. While the wrong oil will not typically cause extensive damage, it does lower gas mileage. The U.S. Department of Energy recommends using only oils with the API Service Seal. These oils are specifically designed to reduce more friction and lower gas mileage.
Newer car models do not significantly improve on gas mileage with frequent air filter replacement. Autos operating with carburated engines can gain up to 14 percent in improved gas mileage with clean air filters, according to the U.S. Department of Energy. A general rule of thumb is to examine and replace dirty air filters with each oil change.
