Gulf Western Gear Lube SAE 80W-90 (20L)

Heavy Duty Extreme Pressure Gear Oil

Product Overview

Gulf Western Gear Lube SAE 80W-90 is a high-performance extreme pressure gear oil designed to protect automotive and industrial gear systems operating under severe loads and demanding conditions. Formulated with premium mineral base oils and advanced sulphur-phosphorus extreme pressure additives, this lubricant delivers excellent wear protection, thermal stability and long service life in manual transmissions, differentials, final drives and other gear applications requiring an 80W-90 viscosity grade.

Modern driveline systems experience high torque, shock loading, sliding gear contact and elevated operating temperatures. Without the correct lubrication, gear teeth and bearings can suffer scuffing, pitting and premature wear. Gulf Western Gear Lube SAE 80W-90 is engineered to maintain a durable oil film across these extreme conditions, reducing metal-to-metal contact and ensuring reliable power transmission.

This oil offers outstanding protection for hypoid gears found in differentials where sliding contact generates high pressure and heat. The carefully balanced additive system forms a protective sacrificial layer on gear surfaces, preventing scoring and extending component life even under heavy load and low-speed, high-torque situations common in off-road vehicles, towing applications and commercial transport.

Supplied in a convenient 20-litre container, Gulf Western Gear Lube SAE 80W-90 is ideal for workshops, fleet maintenance operations, agricultural equipment servicing and industrial users who require dependable gear protection with economical bulk packaging.

Specifications & Approvals

Gulf Western Gear Lube SAE 80W-90 meets or exceeds the following performance standards:

These specifications confirm the product’s capability to handle severe extreme pressure gear environments while maintaining protection against wear, oxidation and deposit formation.

Key Features & Benefits

Extreme Pressure Protection
High-performance sulphur-phosphorus additive technology provides strong protection against scuffing, pitting and gear tooth wear under high load conditions.

Outstanding Hypoid Gear Performance
Specifically designed to lubricate hypoid differentials where sliding gear contact creates high pressure and heat. Ensures reliable operation even under heavy towing or off-road driving.

High Load Carrying Capacity
Maintains a strong lubricant film between gear surfaces to prevent metal contact and extend gear life in heavy duty applications.

Thermal and Oxidation Stability
Resists oxidation and thickening at high operating temperatures, helping maintain clean gear housings and longer oil service intervals.

Corrosion and Rust Protection
Protects gears and bearings against rust caused by moisture or condensation inside gear housings.

Smooth Gear Operation
Reduces friction and noise within manual transmissions and differentials, contributing to quieter and smoother operation.

Wide Temperature Performance
The 80W-90 viscosity grade provides good cold flow for winter start-up while maintaining sufficient thickness at high temperatures to protect gears.

Seal Compatibility
Compatible with standard seals and gasket materials used in automotive and industrial gear systems.

Applications

Gulf Western Gear Lube SAE 80W-90 is recommended for a wide range of automotive and industrial gear applications including:

• Automotive differentials and final drives

• Hypoid gear systems in passenger vehicles and light trucks

• Manual transmissions requiring API GL-4 or GL-5 gear oil

• Commercial vehicle drive axles

• Agricultural machinery gearboxes

• Construction and mining equipment drivetrains

• Industrial gear sets requiring EP protection

It is suitable for vehicles operating under normal driving conditions as well as heavy duty service including towing, load hauling and off-road operation.

Always consult the equipment manufacturer’s manual to confirm the correct viscosity grade and performance level required.

Handling & Storage Advice

Store the product in a cool, dry, well-ventilated area away from direct sunlight and extreme temperatures. Keep containers tightly sealed when not in use to prevent contamination by dust, moisture or other lubricants. Use clean dispensing equipment to maintain oil cleanliness and prevent cross-contamination.

Avoid mixing with other gear oils unless compatibility is confirmed. Dispose of used oil and empty containers according to local environmental regulations and approved waste management procedures. When stored correctly in unopened containers, the product typically has a shelf life of up to five years.
