Assembly Lube 12 Ounce

KLOTZ SYNTHETIC LUBRICANTS Assembly Lube 12 Ounce is a specialized engine assembly lubricant engineered for critical break-in protection during initial engine startup and the first operating hours. Mechanics and engine builders rely on assembly lube to coat internal engine components—pistons, rings, cam lobes, valve lifters, and crankshaft journals—before the engine runs and oil pressure stabilizes. This synthetic formulation clings to metal surfaces longer than conventional motor oil, reducing metal-to-metal contact and preventing wear during the vulnerable assembly-to-ignition window.

The TechniPlate synthetic base stock in this 12 oz bottle delivers superior film strength and oxidation resistance compared to petroleum alternatives, critical when reassembled engines have not yet developed full hydrodynamic oil circulation. The thick, tacky consistency adheres to vertical and horizontal bearing surfaces, cam shafts, and rocker arms without draining into the pan prematurely. As an engine builder's essential tool, this assembly lubricant minimizes initial scuffing and galling on fresh rings and cylinder walls—damage that cannot be reversed once the engine fires. The 12 ounce size is the industry standard single-application quantity for most passenger car and light truck engine builds.

Serious enthusiasts performing engine rebuilds, stroker installations, or first-start procedures on modified or race engines benefit most from this product. Professional mechanics and shade-tree builders alike apply the assembly lube during final assembly—after bearing installation but before the oil pan is sealed—and then drain and flush with fresh motor oil after the first 5–10 minutes of idle running. Compatible with all conventional and synthetic motor oils for post-break-in operation, this KLOTZ product is an insurance policy against catastrophic piston scuff and bearing failure during that critical first moment when metal meets fuel.
