It is designed for four-stroke diesel engines that require API CK-4 or SN performance, including modern low-emission engines with diesel particulate filters. The synthetic blend formulation provides strong wear protection, soot control, and oxidation stability, making it suitable for on-highway trucks, construction equipment, and agricultural machinery. Bulk drums like this are typically purchased by fleet workshops and heavy equipment maintenance operations for cost-effective, high-volume oil changes.
