Prime Guard Full Synthetic SAE 75W-90 Gear Oil is a premium, high-performance lubricant engineered to deliver outstanding protection and performance in extreme operating conditions. Specially formulated with advanced synthetic base oils and a robust additive package, this gear oil is ideal for use in a wide range of automotive and heavy-duty applications where API GL-5 gear oils are recommended.

Packaged in a convenient 5-gallon pail, it’s the perfect solution for fleet operators, service shops, and industrial users who demand long-lasting gear protection and reduced maintenance downtime.

Key Features:

• Full Synthetic Formula: Provides superior thermal and oxidative stability, ensuring consistent performance across a wide temperature range—from cold starts to high-load, high-heat conditions.
• Extreme Pressure (EP) Protection: Fortified with advanced EP additives to protect against gear scuffing, pitting, and wear under heavy loads and shock-loading conditions.
• Outstanding Shear Stability: Maintains viscosity and film strength under severe operating conditions, reducing gear wear and extending service life.
• Corrosion and Rust Inhibitors: Protects internal components from moisture, oxidation, and corrosion—even in high-humidity or wet environments.
• Excellent Low-Temperature Fluidity: Ensures smooth gear shifting and reduced drag during cold starts, improving fuel efficiency and drivability.
• Foam Resistance: Minimizes foaming to maintain consistent lubrication and prevent gear damage.
