Wholesale Options

AMSOIL Severe Gear Synthetic SAE 190 Gear Lube is a professional-grade formulation designed to provide ironclad wear protection under extreme heat and torque while reducing friction for maximum horsepower delivery. Suitable for ultra-high performance or racing applications.

Features and Benefits of AMSOIL Severe Gear Synthetic SAE 190 Gear Lube

  • Provides steadfast wear control in high torque and shock load situations
  • Stays put in the face of heavy G-force cornering
  • Cools hot-running differentials
  • Resists viscosity loss
  • Reduces friction for optimum horsepower
  • Defends against rust during long-term storage

World-Class Wear Protection

AMSOIL Severe Gear Synthetic SAE 190 Gear Lube is formulated with shear stable synthetic base oils and reinforced with extreme pressure additives. This combination provides unparalleled wear protection under extreme loads and hot operating temperatures. Severe Gear SAE 190 protects against metal-to-to-metal damage from jarring shock loads and during extended periods of heavy torque. Reduces the risk of DNF’s and extends component life.

Resists “G-Force Oil Starvation”

High banked corners or fast circle tracks can cause gear oil to gravitate to one side of a differential for extended periods. This can leave one side of the differential completely dry of oil for as long as extreme g-forces are present. Severe Gear Synthetic SAE 190’s ultra-high film strength and stout viscosity always keeps a healthy film of oil in place to protect all differential parts in the face of high g-forces.

Lowers Friction for Cooler Running and Maximum Horsepower

AMSOIL Severe Gear Synthetic SAE 190 uses a friction-fighting synthetic formula that benefits racing applications on two fronts. First, the lower friction helps to decrease operating temperatures and prevent heat build-up during extended periods of hard going. Second, lower friction helps to get every last ounce of useable horsepower to the rear wheels.

Resists Viscosity Breakdown

During extended periods of heavy loads and extreme heat, some gear oils can shear down and lose their viscosity protection. AMSOIL Severe Gear Synthetic SAE 190 Gear Lube uses a shear resistant synthetic base oil that maintains its viscosity during the longest event and over long service intervals.

Rust and Corrosion Protection

Many racing and high performance vehicles are stored for much of the year. During these extended down times, internal rust and corrosion can take hold. Severe Gear SAE 190 is reinforced with an additive package that keeps corrosion at bay until its time to hit the track again.

Suitable Applications for AMSOIL Severe Gear Synthetic SAE 190 Gear Lube

Severe Gear SAE 190 is suitable for any racing or high-performance application requiring a high viscosity gear oil with the API GL-5 specification. Suitable applications include:

  • Drag racing
  • Off-road racing
  • Rock crawling
  • Tractor pull

Limited Slip Differentials and Severe Gear SAE 190

When using this product in limited slip differentials, add AMSOIL Slip-Lock Limited Slip Additive or equivalent.

Mixing AMSOIL Severe Gear SAE 190 with Other Brands

AMSOIL Severe Gear SAE190 Synthetic Oil is compatible with all other brands of conventional, semi-synthetic and synthetic gear oils. While you can safely mix AMSOIL Severe Gear with other brands, this will reduce the drain interval and performance capabilities of AMSOIL gear oil.

The use of any aftermarket oil additives (other than limited-slip friction modifiers) is definitely NOT recommended.

Service Life of AMSOIL Severe Gear Synthetic SAE 190 Gear Lube

Change Severe Gear SAE 190 at regular service intervals or as prescribed by the differential builder. Change more often when differential is immersed in water for extended periods.
