MIDLAND, MICHIGAN / ACCESSWIRE / November 25, 2024 / The TOP TIER™ Approved Fuels program announces the development of new gasoline and diesel fuel performance standards designed to help consumers' vehicle engines and emissions systems operate cleanly and optimally. Sponsored by General Motors, BMW, Toyota, Honda, Audi, Daimler Truck, Ford, Mercedes-Benz, Navistar, Stellantis, Subaru of America, and Volkswagen, TOP TIER™ Approved Gasoline and Diesel have become synonymous with exceptional fuel detergency and engine care.

What to Expect

Fuel marketers can anticipate accessing these new standards on toptiergas.com by early January, with consumer availability of TOP TIER+ Approved Fuels later in 2025.

New Gasoline Performance Standards

The current TOP TIER™ Detergent Gasoline Deposit Control Performance Standard is recognized for defining market-leading port fuel injected (PFI) engine intake valve and combustion chamber deposit cleanliness requirements.

Introducing the TOP TIER+™ Approved Gasoline Performance Standard will extend these benefits to newer, higher-efficiency gasoline direct-injected (GDI) engines. The new gasoline standard will include a GDI Fuel Injector Cleanliness Engine Dynamometer Test while monitoring for optimal emissions and combustion behavior.

Updated Diesel Performance Standards

Today's TOP TIER™ Diesel Fuel Performance Standard has been streamlined into two levels of performance requirements for greater market flexibility:

• TOP TIER™ Approved Diesel Performance Standard has been revised to focus on detergency and contamination cleanliness requirements.

• TOP TIER+™ Approved Diesel Performance Standard adds enhanced fuel injection hardware wear protection and greater fuel storage stability to the base-level features.
