Customer Benefits
Helps save on maintenance
Proven metallo-organic anti-wear additive system helps resist wear by forming a protective layer on contact surfaces under all service conditions.
Helps prolong periods between overhauls
Metallic detergent and ashless dispersant additive system helps resist the formation of high temperature deposits in diesel engines. Good oxidation stability helps resist oil degradation and helps protect against oil thickening, and oil line and filter plugging.
Helps preserve power and performance
Metallic detergent and ashless dispersant additive system helps preserve power and performance by providing good control of high-temperature piston and ring deposits.
Applications
Suitable for the following applications whenever the manufacturer recommends monogrades:
- Mixed fleets of diesel engines (high-speed, four-stroke, turbocharged or naturally aspirated)
- Gasoline engines (four-stroke) in mixed fleets of both diesel and gasoline engines
- Commercial road transport
- Off-highway vehicles
- Agricultural tractors
- High speed diesel engines in marine service (e.g., fishing boats, river transport)
- Generator sets
- Mobile hydraulic systems (where oil type and viscosity are appropriate)
