WStJrl Article on Gasoline Quality

Interesting article in WStJrl of 4/7/05 regarding detergent levels in gasoline. BMW, Honda, GM and Toyota all recommend gasoline that meets a higher standard for detergents than the minimum set by EPA. Those making the "top tier" list for all grades of their gasoline include Shell, Chevron. ConocoPhillips brands (Phillips 66, Conoco, 76), Quik Trip, Entec Stations and MFA Oil. Notably absent was BP/Amoco. Article also mentioned the option of adding a detergent gasoline additive purchased at an auto parts store every 3,000 miles or filling up occasionally with a brand that includes these extra detergents but it stands to reason that a constant level of adequate detergents would be better at keeping valves and fuel injectors clean.
