Use in API GL-5, hypoid gear applications that require higher-viscosity oil, including off-road race trucks, rock racers and crawlers, competition tractors, funny cars, dragsters and heavy equipment. Where limited-slip performance is required, useAMSOIL Slip Lock^®limited-slip additive.

PROTECTS AGAINST WEAR

• Extra-heavy treatment of additives and shear-stable, heavy synthetic base oils promoteincreased film strength for maximum wear protection.
• Cushions metal surfacesand absorbs impact of moving parts.
• Proprietary extreme-pressure additives form an iron-sulfide barrier on gear surfaces for theultimate line of defenseagainst wear, pitting and scoring.

PROVIDES FAST PROTECTION

• Does not contain waxes that solidify in the cold inherent to conventional oils, meaning it providesexcellent fluiditydespite its high viscosity toquickly reach gears and bearings at startup.
• Superior fluidity reduces viscous drag and energy loss, helping drivers putmaximum power to the ground.

CLINGS TENACIOUSLY TO PARTS

• Specifically engineeredfor high-horsepower, high-torque conditions where centrifugal gear lube sling-off is encountered.
• Tenacious formulation clings to gears and bearings formaximum protectionduring shock loading, high G-forces and when ring and pinion gears are run at steep angles.
• Provides excellent reliability andhelps extend gear life.
