To determine which minor maintenance defects are most important to keep a car's fuel mileage up to par, a series of ten separate tests was run on an mpg-gauge-equipped test car. The tests showed that defects having to do with ignition timing and spark plugs cause significant mpg loss, ranging from 14 to 25 percent. Other defects showed only minor losses in fuel economy, with one exception, which was an increase in fuel economy when tires were inflated above the recommended specs.
