Reduces Fleet Maintenance Costs
Combination of high performance hydrocracked base fluids and specially balanced metallic detergent and ashless dispersant additive system, provides excellent overall engine cleanliness in all service conditions. Optimized additives confer high degree of soot dispersancy required to maintain oil drain intervals in diesel and gasoline engines. Exceptional oxidation stability protects against the formation of gums and varnish at elevated temperatures.
Prolongs Engine Life
Efficient 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.
Power and Performance
