Severe Gear® 80W-90

   Severe Gear® 80W-90

AMSOIL Severe Gear 80W-90 Synthetic Gear Oil is specifically designed for heavy-duty gear applications, such as pickup trucks, SUVs, and heavy machinery.

This premium-grade gear oil provides outstanding performance in every aspect, including high viscosity stability, consistent shear strength, a strong protective film, superior gear wear reduction, and exceptional resistance to extreme pressure, with no degradation in lubrication quality.

Benefits

Outstanding Performance
AMSOIL Severe Gear 80W-90 delivers superior performance compared to conventional gear oils on the market. It provides better protection for gears and bearings, reduces friction and heat more effectively, and extends the overall lifespan of gears.

Extreme Temperature Operation
AMSOIL Severe Gear 80W-90 performs well in both extremely high and low temperatures. It resists breakdown due to high heat and protects against acid formation, sludge, and carbon deposits. In very cold conditions, the lubricant structure prevents wax formation, ensuring smooth gear operation. It also helps improve fuel efficiency.
