Product Code

Outstanding Thermal & Oxidation Stability

Synthetic base stocks provide significantly higher resistance to thermal degradation and oxidation than mineral gear oils — maintaining oil integrity in heavily loaded transmissions and axles operating at sustained high temperatures, and enabling extended drain intervals.

Excellent Low-Temperature Fluidity — Pour Point -51°C

Remains fluid at extremely low temperatures without channelling — ensuring immediate oil circulation to transmission and axle gear sets on cold starts in high-altitude, cold-weather and desert conditions where temperature swings are extreme.

High Inherent Viscosity Index — Wide Temperature Range

Outstanding viscosity-temperature properties ensure consistent oil film strength across the full operating temperature range of heavy-duty transmissions and axles — from cold starts to sustained high-load high-temperature operation in mining and long-haul applications.

Excellent Shear Stability

Maintains viscosity grade throughout extended drain intervals under severe mechanical shear in high-torque axles and transmissions — preventing the viscosity loss that causes premature wear and early oil change requirements in conventional gear oil applications.

Increased Load-Carrying Capability

Advanced EP additive system provides outstanding protection under high-speed/shock load, high-speed/low-torque and low-speed/high-torque conditions — the three loading scenarios that cause premature gear and bearing failure in under-specified drivetrain lubricants.

Potential Fuel Economy Improvement

Lower internal friction in synthetic-lubricated transmissions and axles contributes to measurable fuel economy improvement versus conventional mineral gear oils — a meaningful saving across high-mileage long-haul fleets and continuous-shift mining operations.

Extended Service Capability

Engineered for applications where extended service intervals and extended warranties are required — reducing the frequency, cost and safety exposure associated with transmission and axle oil changes across large fleet and mining operations.

Wear, Corrosion & Seal Protection

Optimally balanced friction control, wear protection, rust and corrosion prevention and seal compatibility — contributing to extended gear and seal life, smooth operation and high load high torque capability over a wide range of drivetrain applications.

Heavy-Duty Manual Transmissions

Non-synchronised and synchronised manual transmissions on heavy-duty on-highway trucks, buses and vans requiring API GL-4, GL-5 or MT-1 specification gear lubricant.

Rear Axles & Final Drives

Hypoid rear axles and final drives on on-highway and off-highway equipment requiring API GL-5 high-performance gear lubricant — trucks, buses, mining haul equipment and construction machinery.

Mining & Off-Highway

Transmissions and axles on mining haul trucks, ADTs, construction and quarrying equipment across the Northern Cape where extended drain capability and sustained performance under shock loading are critical.

Agricultural Equipment

Tractor transmissions and axles, combine harvester drives and other agricultural equipment requiring API GL-4 or GL-5 synthetic gear lubricant across the Western Cape farming sector.

Transfer Cases & Differentials

Transfer cases and differentials in on-highway and off-highway equipment where GL-5, GL-4, MT-1 or MIL-PRF-2105E specification is required — initial fill, top-off and refill applications.

Extended Drain Applications

Applications where extended service intervals and OEM extended warranties are required — Eaton Roadranger, Meritor and Dana Spicer extended drain and warranty programmes.
