Today’s equipment is working harder under harsher conditions to produce the same output as it always has. As the going gets tough, Schaeffer’s heavy-duty diesel oils provide the extra muscle your engine needs to preserve durability.
When operating temperatures rise, our proprietary additives allow our oils to maintain performance for more hours and over more miles. Better oxidation and thermal stability means optimal performance, less oil consumption and longer component life.
Schaeffer’s robust oils resist breaking down in higher operating temperatures, allowing your equipment to consistently run effectively.
Blended with enhanced detergency and dispersancy additives, our oils shield your engine from low temperature sludge buildup and high temperature deposits.
Schaeffer’s oils are formulated with proprietary friction modifiers Micron Moly and Penetro to reduce wear and friction on bearings, rings, pistons, cylinders and valve-trains.
As temperatures drop, Schaeffer’s oils still flow freely and quickly circulate throughout your engine the moment it starts. Our Supreme 9000 Oils provide maximum cold weather startup protection in temperatures as low as -40°.
Schaeffer’s oils are routinely tested each year, and the results consistently show our oils produce real savings to your bottom line.
Synthetic plus, heavy-duty diesel oil that provides stronger durability, better soot control and stronger wear protection to equipment running in stop-and-go, excessive idling and short haul situations. Exceeds API CK-4.
