Features & Benefits
Ultimate Wear Protection
Fully synthetic base stocks and advanced additive technology deliver the highest level of wear protection — extending engine life beyond conventional and semi-synthetic formulations in the most demanding heavy-duty diesel applications.
Superior Soot Handling
Outstanding soot dispersancy and viscosity control — preventing the soot agglomeration that causes viscosity increase, filter plugging and abrasive wear in high-output Euro VI diesel engines.
DPF & Aftertreatment Protection
Low SAPS formulation protects DPF, SCR and DOC systems from premature poisoning and blocking — essential for Euro VI fleet compliance and long-term aftertreatment system reliability.
Extended Drain Capability
Exceptional oxidation stability and TBN retention maintain protection throughout extended drain intervals — reducing the frequency and cost of oil changes in high-utilisation fleets and mining equipment.
Outstanding Low-Temperature Performance
5W low-temperature viscosity grade ensures rapid oil circulation on cold starts — minimising the cold-start wear that accounts for the majority of engine life degradation in mobile equipment.
Excellent Fuel Economy
Reduced internal friction from synthetic base stocks contributes to measurable fuel economy improvement — a meaningful saving across high-mileage long-haul fleets and continuous-shift mining operations.
Applications
Euro VI On-Highway Trucks
Modern Euro VI trucks and buses equipped with DPF, SCR, EGR and DOC aftertreatment systems from Volvo, Scania, MAN, Mercedes-Benz, DAF and Renault — where the highest level of synthetic oil protection is specified.
Mining & Off-Highway Equipment
Heavy-duty mining haul trucks, excavators and off-highway equipment where maximum engine protection, extended drain capability and synthetic oil performance are required.
High-Performance Diesel Fleets
Mixed fleets operating under the most demanding conditions — where a single premium fully synthetic oil provides maximum protection across all modern diesel engine types.
