Diesel Performance Additives

The WWFC committee recommends that countries adopt specifications to promote good housekeeping practices, as described in CEN/TR 15367-3, for example. Where such specifications do not yet exist, retailers may choose to participate in voluntary programs such as the new TOP TIER™ Diesel program, which helps assure acceptable quality diesel fuel at the refueling pump for deposit control additive usage, oxidative stability, lubricity and water and particulate contamination controls. Like its sister program for gasoline, this program provides a trademarked, licensed, fuel performance standard enforced by its sponsoring automakers and engine manufacturers. 

^{All licensed TOP TIERTM diesel fuel must meet the established OEM performance standard which includes minimum requirements for detergency, lubricity, and oxidation. This performance standard exceeds the requirements of ASTM D975 and CGSB-3.517 with respect to deposit control}
