AMSOIL, SEVERE GEAR® 75W-90 100% Synthetic Gear Lube, Universal Fit

AMSOIL SEVERE GEAR® 75W-90 Synthetic Gear Lube

Engineered for the most demanding environments, AMSOIL SEVERE GEAR® 100% Synthetic Extreme-Pressure (EP) Gear Lube is a premium-grade lubricant designed for hard-working vehicles. Whether you are towing heavy loads, navigating off-road terrain, or operating heavy machinery, this gear oil maintains its viscosity to provide a long-lasting shield against metal-to-metal contact and gear failure. It is specifically overbuilt to handle high-horsepower applications, providing a level of gear and bearing protection far beyond conventional lubricants.

Modern pickups and SUVs generate intense pressure within their differentials. SEVERE GEAR is thermally stable, preventing the formation of carbon deposits and varnish that lead to increased friction. Its wax-free synthetic construction improves cold-flow properties, reducing internal drag during startup and operation for improved efficiency in all seasons.

Features

• Ultimate Wear Defense: Proprietary additives create an iron-sulfide barrier on gear surfaces to prevent wear, pitting, and scoring under high-load conditions.
• Prevents Thermal Runaway: Specifically designed to control friction and stop rapid heat buildup, protecting against catastrophic component damage during high-stress operation.
• Extreme Temperature Versatility: Excels in both scorching heat and sub-zero cold, resisting breakdown while improving cold-weather shifting performance.
• Extended Service Life: Inhibits lubricant degradation and resists the formation of acids and varnish, helping equipment run better and last longer.
• Improved Fuel Economy: High cold-flow efficiency reduces drag, leading to better fuel economy and smoother operation in winter conditions.
• Severe-Duty Ready: Ideal for towing, hauling, off-roading, and commercial fleets operating in challenging terrains.
