Severe Gear® 75W-90

   Severe Gear® 75W-90

AMSOIL Severe Gear 75W-90 Synthetic Gear Oil is specifically formulated for heavy-duty applications such as pickup trucks, SUVs, and heavy machinery.

AMSOIL Severe Gear 75W-90 is a premium-grade synthetic gear oil that delivers exceptional performance in every aspect, such as maintaining high viscosity, providing stable shear strength, forming a strong protective film, reducing gear wear, and withstanding extreme pressure without degradation of lubrication quality.

Benefits

Outstanding Performance
AMSOIL Severe Gear 75W-90 Synthetic Gear Oil delivers superior performance compared to conventional gear oils available on the market. It offers better protection for gears and bearings, reduces friction and heat more effectively, and extends gear life.

Extreme Temperature Operation
AMSOIL Severe Gear 75W-90 performs well under both extremely high and low temperatures. It resists breakdown due to high heat, protects against acid formation, sludge, and carbon deposits. In very cold conditions, its structure prevents wax formation, allowing gears to operate smoothly. Additionally, it helps improve fuel efficiency.
