Special composition diesel engine lubricant, suitable for heavy professional on/off road vehicles, international transport vehicles, buses and distribution trucks operating in rather stressful conditions. Suitable for engines without diesel particulate filters (DPF), most EGR engines and most engines equipped with SCR NOx reduction systems. However, recommendations may vary among engine manufacturers. Thus, in case of doubt, please consult manufacturer and/or retailer manuals. May also be used in older engines, provided the fuel used has sulfur content of <0.5 %.
