The conclusion of a study released Thursday by the AAA auto club has revealed that many motorists are clogging their car's engine by not using gasoline with enough added detergents.
Federal rules in place since 1996 require all gasoline to have some engine-cleaning additives, but many major brands have extra detergents.
AAA said tests it commissioned from an independent lab found that lesser gasolines left 19 times more deposits on engine intake valves than so-called top-tier fuels after the equivalent of 4,000 miles of driving, which reduce a car's mileage, increase emissions and hurt performance, especially on newer cars.
AAA's director of automotive engineering, Greg Brannon, said car owners can undo some deposits by switching gasoline for a few thousand miles.
