Step 1
Keep your engine tuned according to your owner's manual. The Federal Trade Commission (FTC)says that by tuning your engine you can increase gas mileage by an average of four percent.
-
Step 2
Keep tires properly inflated. Under-inflated tires is probably the number one reason cars receive lower than expected fuel mileage. Tires that are under-inflated by only five pounds could cause a two percentage drop in mileage.
-
Step 3
Keep tires properly aligned. When tires are not align they cause additional drag. This increases fuel consumption and lowers fuel mileage.
-
Step 4
Change your oil regularly. The Department of Energy (DOE) and Environmental Protection Agency (EPA)both say that using the manufacturer's recommended grade of motor oil will improve your gas mileage.
-
Step 5
Replace air filters regularly. Replacing clogged air filters can increase gas mileage by up to ten percent
-
Step 6
Drive efficiently. Avoid going over posted speed limits. Gas mileage decreases rapidly when you go over sixty miles per hour. Don't drive aggressively. By avoiding jackrabbit starts and stops you can improve gas mileage by up to five percent.
-
Step 7
Combine trips. Engines are at their peak of efficiency when they are warm. Several short trips taken from a cold start uses twice as much fuel as one trip covering the same distance taken with a warm engine.
-
Step 8
Remove excess weight from trunk. An extra 100 pounds in the trunk can reduce a car's fuel efficiency by two percent.
