Maintains engine life 

High efficiency dispersant combination plus proven metallo-organic anti-wear additive system provides excellent protection against wear of critically loaded components under all operating conditions. Multigrade viscosity provides additional protection against wear at start-up and under high temperature operating conditions. 
 

Preserves full power and performance 

Proven metallic detergent additive system preserves full power and performance by providing good upper-ring-belt deposit control under the high temperatures encountered in turbocharged diesel engines. 

Reduces maintenance costs 

Combination of high performance base fluids and carefully balanced metallic detergent and ashless dispersant additive system, provides effective overall engine cleanliness in all service conditions. 

Maintains oil and filter service intervals 

Highly effective antioxidant system inhibits the formation of sludge forming materials which can lead to premature oil thickening and filter plugging. High degree of soot dispersancy maintains oil drain intervals in modern engine designs. Very effective dispersant system further assists by keeping insoluble contaminants finely suspended in the oil, minimizing their ability to block oil filters.
