ExxonMobil · Mobil Delvac™ · Authorised Distributor — Western Cape & Northern Cape
Mobil Delvac™ 1 Gear Oil 75W-140 is a fully synthetic heavy-duty drivetrain lubricant engineered for axles, final drives and differentials operating under extreme pressure and shock loading conditions. Incorporating synthetic base stocks and an advanced additive system, it delivers significantly stronger film strength at high temperatures than mineral gear oils — while maintaining effective lubrication at sub-zero temperatures without channelling. Designed for heavy-duty on-highway and off-highway drivetrains requiring API GL-5 and Scania STO specification performance, it provides outstanding thermal stability, shear stability, corrosion protection and wide temperature range capability that mineral 80W-140 oils simply cannot match. Available in 208L drum from Orbit Industrial — authorised Mobil distributor for the Western Cape and Northern Cape.

Why Fully Synthetic 75W-140 — Not Mineral 80W-140
Superior High-Temperature Film Strength
Synthetic base stocks provide an inherently higher viscosity index — delivering stronger oil film between hypoid gear teeth at high operating temperatures where mineral 80W-140 oils thin out and film strength drops below the threshold required to prevent metal-to-metal contact under extreme pressure.
Outstanding Low-Temperature Fluidity — Pour Point -45°C
Effective lubrication at below-freezing temperatures without channelling — ensuring immediate oil circulation to axle gear sets on cold starts in high-altitude and cold ambient conditions where mineral gear oils can channel and leave components momentarily unprotected.
Excellent Shear Stability — Stays In Grade
Maintains viscosity grade throughout the drain interval under the severe mechanical shear experienced in high-torque hypoid axles and final drives — preventing the viscosity loss that causes premature wear and early oil change requirements in mineral gear oil applications.
Outstanding Thermal & Oxidation Stability
Protects against thermal degradation and oxidation in heavily loaded axles running hot under sustained high-load conditions — extending oil service life, reducing sludge and deposit formation, and preserving axle component integrity over extended drain intervals.
Reduced Wear & Corrosion Protection
Advanced EP additive system protects hypoid gear teeth under high-speed/shock load, high-speed/low-torque and low-speed/high-torque operating conditions — the three critical loading scenarios that cause premature axle and final drive gear failure in under-specified gear oils.
Fuel Economy Contribution
Lower internal friction in synthetic-lubricated axles and final drives contributes to measurable fuel economy improvement versus mineral gear oil equivalents — a meaningful saving across high-mileage long-haul truck fleets and high-utilisation mining haul equipment.
Recommended Applications
Heavy-Duty Truck Axles
Hypoid rear axles and tandem axles on long-haul and regional distribution trucks from Volvo, Scania, MAN, Mercedes-Benz, DAF, Renault, Iveco and UD Trucks requiring API GL-5 performance.
Mining Haul Truck Final Drives
Final drives and wheel reduction units on Cat, Komatsu, Bell and Liebherr rigid dump trucks operating under sustained high-torque, high-load conditions in open pit mining across the Northern Cape.
Differentials & Transfer Cases
Differentials, final drives and transfer cases in on-highway and off-highway equipment where API GL-5 or multipurpose EP gear lubricant specification is required.
Construction & Earthmoving
Axles and final drives on ADTs, graders, wheel loaders and compactors operating in construction and civil engineering applications across the Western Cape and Northern Cape.
Agricultural Equipment
Tractor axles and final drives, combine harvester drive systems and other agricultural equipment requiring high-viscosity API GL-5 gear lubricant in demanding seasonal and heavy-load conditions.
Winch & Crawler Drives
Winch reduction gears and crawler vehicle propulsion gear drives exposed to severe low temperatures and sustained high shock loading — applications where the -45°C pour point provides reliable cold-start protection.
Note: Mobil Delvac 1 Gear Oil 75W-140 is not recommended for applications requiring API GL-4 level performance. Always confirm OEM specification before application.
