A TOP TIER™ Diesel Fuel program is being launched to benefit owners of diesel-powered vehicles and diesel-powered equipment. Today’s diesel engines typically utilize high pressure common rail (HPCR) technology where smaller tolerances and higher fuel pressures are seen. HPCR engines will benefit from the requirements stated in the TOP TIER™ Diesel Performance Standard, developed by a consortium of diesel Original Equipment Manufacturers (OEMs). Retailers offering diesel fuel and biodiesel blends meeting the TOP TIER™ Diesel Fuel requirements will display the TOP TIER™ Diesel Fuel logo at the dispensers or elsewhere in their stations starting October 2017.
