What You'll Learn
TOP TIER™ Diesel Fuel
The program is currently sponsored and overseen by major automotive companies such as General Motors, Volkswagen, Daimler Truck, Navistar, and Ford. To be considered TOP TIER™ Approved Diesel, the fuel must meet specific requirements outlined in the TOP TIER™ Diesel Fuel Performance Standard. This standard mandates the use of additive packages to reduce internal and external injector deposits, enhance lubricity to reduce wear and tear on pumps and injectors, improve fuel stability, and minimize particulate and water contamination.
The TOP TIER™ Diesel Performance Standard goes beyond the ASTM D975 and D7467 specifications for diesel and biodiesel blended fuel in the United States. It emphasizes the importance of good housekeeping practices to maintain fuel system cleanliness and protect against water and particulate contamination.
When purchasing diesel fuel, it is important to prioritize fuel quality and freshness. Clean, well-maintained stations with modern storage tanks and high sales volume are more likely to provide better-quality diesel fuel. However, it is worth noting that diesel fuel branding may not always be indicative of the fuel's origin or quality, as manufacturers often utilize common pipeline systems for transportation and storage.
To ensure you are purchasing TOP TIER™ Approved Diesel, it is advisable to use the TOP TIER Station Finder or look for the TOP TIER™ Approved Diesel sticker on the pumps. This certification guarantees that the diesel fuel meets the stringent standards set by the TOP TIER™ Diesel Fuel Program and its sponsoring automotive companies.
