Extreme Pressure Lube #3 (4oz.)

Extreme Pressure Lube #3 (4oz.) is a specialized engine assembly lubricant engineered for high-stress internal engine components where extreme pressure conditions demand superior film strength and protection. Whether you're building a high-performance engine, restoring a classic motor, or maintaining critical valve train assemblies, this advanced formula prevents metal-to-metal contact and wear during assembly, break-in, and sustained high-load operation. Designed for serious enthusiasts and professional mechanics who refuse compromise on engine longevity, this 4-ounce bottle delivers concentrated protection where standard motor oil simply cannot perform.

The Extreme Pressure Lube #3 formulation incorporates anti-wear additives and boundary lubrication agents that create a robust protective layer on cam lobes, lifters, rocker arms, and other cam-follower contact surfaces under peak loading. This extreme pressure technology is essential during initial engine startup and high-RPM operation, where transient oil starvation and shock loads would otherwise cause accelerated wear or scuffing on precision-machined surfaces. The concentrated 4-ounce format means a small quantity goes a long way—typical application requires only 0.5 to 1 ounce per engine assembly, making this bottle sufficient for multiple engine builds or comprehensive maintenance programs.

Extreme Pressure Lube #3 is ideal for flat-tappet cam engine builds, hydraulic and mechanical lifter systems, and any high-performance or forced-induction application where valve train stress peaks. Apply directly to cam lobes, distributor gears, timing chain components, and valve stem tips during assembly; use as a break-in additive in fresh oil during initial startup and dyno testing. Compatible with conventional mineral and synthetic motor oils, this product pairs seamlessly with popular break-in protocols and cold-start engine protection strategies, ensuring your investment in engine internals receives maximum safeguard from the first revolution.
