Engineered with advanced Extreme Pressure (EP) additives to shield vital gear teeth against shock-loading and shear, ensuring smooth, reliable power transmission from first gear to last.
The automotive drivetrain — consisting of manual gearboxes, transaxles, and rear-axle differentials — is subjected to extreme mechanical shear, high torque, and shock-loading forces. Without adequate lubrication, these heavy metal-on-metal contacts can lead to rapid gear pitting, scoring, and eventual drivetrain failure.
Prymol's Automotive Gear Oil is engineered with advanced Extreme Pressure (EP) additives to shield vital gear teeth and ensure smooth, reliable power transmission in every condition the road throws at it.
Formulated for comprehensive protection across manual transmissions, steering gearboxes, and hypoid differentials in passenger cars, light commercial vehicles, agricultural machinery, and heavy-duty trucks — including full-load starts and steep-incline climbs.
All-Vehicle ChoiceFrom city hatchbacks to fully loaded heavy trucks — EP-90 is formulated to provide comprehensive protection across a vast range of automotive drivetrains.
This high-performance, multi-application gear oil is formulated to provide comprehensive protection across a vast range of automotive drivetrains. It is highly suitable for manual transmissions, steering gearboxes, and hypoid differentials in passenger cars, light commercial vehicles, agricultural machinery, and heavy-duty trucks. The specialised sulfur-phosphorus EP additive chemistry forms a highly resilient sacrificial layer on gear surfaces, preventing metal-to-metal welding and scoring even when the vehicle is starting under full cargo capacity or climbing steep inclines.
EP-90's extreme-pressure chemistry is built to perform across the full range of drivetrain components — wherever heavy metal-on-metal contact demands a resilient, shear-stable film.
| Component | Typical Vehicle | Why EP-90 |
|---|---|---|
| Manual Transmission | Passenger cars & LCVs | Smooth shifting, reduced noise |
| Steering Gearbox | Cars, trucks, tractors | Shock-load & wear protection |
| Hypoid Differential | Heavy-duty trucks | EP film prevents scoring |
Protects gear components against heavy shock-loading, preventing micro-pitting and surface fatigue even under full-load starts and steep climbs.
Resists oil thickening and chemical breakdown under high operating temperatures, ensuring prolonged gear life and extended oil drain intervals.
Advanced anti-rust and anti-corrosion inhibitors safeguard yellow metals like copper and bronze synchronisers, and ferrous components, from moisture and acidic degradation.
Optimises frictional properties to provide smooth manual gear shifts, reducing operational drivetrain noise and vibration.
From single-litre retail bottles for top-ups to full 210-litre drums for service centres and distributors — EP-90 is available in five standard and commercial formats.
