Duragard® Diamond Plate® SAE 30WT Heavy Duty Single Grade Engine & Transmission Oil is formulated with select Group-II hydro cracked clear base oil blends that provide superior low temperature fluidity and extraordinary high temperature film strength that simply cannot be achieved using conventional mineral base oils. Various weights for mixed fleets requir¬ing performance typical of API Service Classification CF-4/CF-2, CE, CDII/SH lubricants - gasoline or diesel. They provide high detergency levels, soot dispersancy, oxidation stability, and excellent wear protection. The SAE 30wt HD Oil meets the performance requirements of typical of Allison C-4, Caterpillar TO-2 fluids, and the non-synthetic requirements typical of CD/GL-1 for Eaton / Fuller Road Ranger & Spicer / Dana transmissions.

Duragard® Diamond Plate® SAE 30WT Heavy Duty Single Grade Engine Oil is compounded from high viscosity index, specially hydro-co processed base oils combined with potent detergent-dispersants, anti-wear additives, anti-oxidants, defoamers, and pour-point depressant compounds. The superior high temperature volatility characteristics result in superior oil consumption control. Stay-in-grade shear stability enables the oil to maintain viscosity in severe high temperature and heavy load conditions. The direct benefit is extended engine and component life.

Duragard® Diamond Plate® SAE 30WT Heavy Duty Single Grade Engine Oil is formulated with less than 1.0% sulfated ash to meet the requirements typical of 2 cycle Detroit Diesel engines, and are dyed traditional amber color for visibility and leak identification.

Duragard® Diamond Plate® SAE 30WT Heavy Duty Single Grade Engine Oil is recommended for type MIL-L-2104F, MIL-L-2104E, MIL-L-2104B/C/D, and type CE/CD/CC applications.
