Customer benefits 
 

Saves on fleet maintenance costs 

Metallic detergent and ashless dispersant additive system provides both high temperature deposit control in diesel engines and low temperature sludge control in gasoline engines. High oxidation stability protects against the formation of gums and varnish at elevated temperatures, and resists thickening, and oil line and filter plugging. 

Longer engine life 

Proven metallo-organic anti-wear additive system protects 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. 

Maintains high power and performance 

Metallic detergent and ashless dispersant additive system maintains high power and performance by providing very good upper-ring-belt deposit control, particularly under the high temperatures encountered in turbocharged diesel engines. 

Low inventory costs 

Mid-ash, medium dispersancy formulation provides very good overall performance in mixed fleets of different engine designs, allowing fewer oils to be stored and reducing
