All gasoline sold in the U.S. meets minimum requirements set by the government. The differences between brands come in the additives and detergents added to the blend to help extend the life of the engine.
Some fuel companies — working with major automakers that include BMW, Fiat-Chrysler, General Motors, Honda, Mercedes-Benz, Toyota, Volkswagen/Audi — have taken it a step further, setting a higher standard that has become known as Top Tier fuels. Brands that qualify as Top Tier contain additional detergents beyond the minimum requirements, and help prevent carbon buildup in car engines.
Over time, the furnace that is the modern engine will accumulate carbon residue, a byproduct of the motor's combustion process that happens thousands of times per minute. Like barnacles on a boat, carbon deposits can build up on vital engine parts, like valves, pistons and the combustion chamber. As the carbon accrues, engines will run rougher and less efficiently (ie, less power or decreased fuel economy).
