Soot control
Helps keep viscosity in range as diesel soot loads the oil during long hours of work.
Engine Oils
Heavy-Duty Diesel Engine Oils
High-performance diesel lubrication for trucks, buses, generators, construction equipment and agricultural machinery operating under demanding service conditions.
Product family
Formulated for soot, load and long hours in diesel service.
Heavy-duty diesel oils are selected around soot handling, TBN retention and film strength under sustained load. This family is aimed at trucks, buses, generators and off-highway diesels rather than passenger-car gasoline engines.
Drain intervals, fuel sulphur and OEM claims will be filled in from approved data. The rows below show how grades will sit on the page.
