How do Shell gasolines compare with other gasolines in the United States?
There is a difference in the gasoline you choose. While all gasolines sold in the U.S. are required to meet the EPA’s minimum detergency standard for gasoline, referred to as LAC (lowest additive concentration), all Shell gasolines meet the much more stringent TOP TIER Detergent Gasoline standard created by leading auto manufacturers. Gasolines that meet the TOP TIER standard keep engines cleaner to help the vehicle perform better. Low-quality discount gasolines can allow performance-robbing gunk to form in your engine.
