Outstanding Soot Dispersancy

Exceptional control of oil thickening due to soot build-up — maintaining optimum oil viscosity throughout the drain interval in turbocharged marine high-speed diesel engines where soot generation is high.

Outstanding Oxidation Resistance

Excellent resistance to oxidation and high temperature varnish deposits — keeping engine internals clean and extending drain intervals in severe-duty continuous-operation marine diesels.

Excellent Corrosion Protection

Outstanding corrosion protection for all engine metals — protecting bearings, cylinder liners and other critical surfaces from the acid and moisture corrosion encountered in marine environments.

Low and High Sulphur Fuel Compatibility

Performs equally well on low and high sulphur distillate fuels — providing fleet operators flexibility in fuel selection without changing lubricant specification.

Multi-Grade Cold Start Protection

15W low-temperature performance ensures rapid oil circulation on cold starts in marine vessels operating in cooler climates — reducing cold-start wear that accounts for the majority of engine life degradation.

Broad OEM Coverage

Approved or recommended by all major marine high-speed diesel engine builders — simplifying lubricant management for mixed fleets and vessels with multiple engine types.

Marine High-Speed Diesel Engines

High-speed diesel main propulsion and auxiliary engines on fishing vessels, workboats, ferries, coastal vessels and offshore support vessels — Caterpillar 3500 series, Cummins, Volvo, Daihatsu, Yanmar and other major OEMs.

Generator Sets

Marine diesel generator sets on vessels, offshore platforms and coastal installations — where continuous duty and marine environment demand the highest quality multi-grade diesel engine oil.

Heavy-Duty Land Diesel Engines

Can also be used in heavy-duty land-based diesel engines including mining haul trucks, construction equipment and transport fleet where API CI-4 multi-grade performance is required.
