20 Years of Excellence
This year marks the 20th anniversary of the TOP TIER™ Approved Fuels Program, an initiative that has reshaped the landscape of fuel detergency standards and clean engine vehicle performance since its inception. Collaboratively introduced in 2004 by General Motors, BMW, Toyota, and Honda, TOP TIER™ Approved Gasoline and Diesel have become synonymous with exceptional fuel quality and engine care. Now, they are joined by seven more leading auto manufacturers including Audi, Daimler Truck, Ford, Mercedes-Benz, Navistar, Stellantis, Subaru of America, and Volkswagen.
