Top Tier Gasoline

A few years ago, several car manufacturers worked together to develop fuel standards that were higher than those imposed by the federal government. Some gasoline manufacturers welcomed the stricter standards and signed up with the program to produce Top Tier gasoline. These auto manufacturers believe that higher gasoline standards result in cleaner engines, cleaner burning, and better performance. Current EPA minimum requirements are substantially below the Top Tier standard. Audi, BMW, General Motors, Honda, Mercedes-Benz, Toyota, and Volkswagen call for the use of Top Tier gasoline in most of their vehicles. The following fuels sold in our area meet the Top Tier standard: BP, Chevron, Costco Wholesale, CountryMark, Exxon, Mobile, Shell, and Texaco. Gasoline refiners that participate in the program guarantee that all the fuel they sell in the United States meets Top Tier standards.
