Diesel Performance Standard

TOP TIER™ Diesel Fuel was developed to improve performance, in turn helping the diesel fuel retailers, auto and engine manufacturers, and particularly those who drive or use diesel-powered equipment.  Relative to the ASTM D975 and D7467 specifications for diesel and biodiesel blended fuel in the U.S., the TOP TIER™ Diesel Performance Standard requires detergents to reduce deposits on the fuel injectors (both internal and external), improve lubricity (less wear on injectors and in the engine), improve fuel stability (less deposits in the fuel system components), and provide more protection against water and particulates introduced into the fuel prior to dispensing into vehicles or equipment.
