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.
