Engine Assembly Lube Case 12 x 6oz Bottles

Engine Assembly Lube Case 12 x 6oz Bottles from PENNGRADE Motor Oil is purpose-built for the critical break-in phase of new or rebuilt engines. Whether you're assembling a stroker, a freshly bored block, or a completely remanufactured short block, this assembly lube prevents metal-to-metal contact during initial startup—the window where most catastrophic wear occurs. Available as a full case of twelve 6-ounce bottles, it's sized for serious builders and shops that service multiple engines simultaneously or maintain consistent inventory for repeat builds.

PENNGRADE's formulation clings to critical surfaces—cam lobes, lifters, rocker arms, main journals, and cylinder walls—creating a protective film that oil circulation alone cannot guarantee during those first dangerous revolutions. Unlike conventional motor oil, assembly lube features extreme-pressure additives and enhanced film strength that survive the shock loads of cold start and low-idle speeds before the engine develops full oil pressure. The 6-ounce format makes controlled application straightforward: coat bearing surfaces, pivot points, and friction zones with precision, avoiding oversaturation that complicates cleanup and can trap debris in tight clearances.

Mechanics, engine builders, and performance shops benefit most from bulk case quantities—one bottle per cylinder bank or major assembly station eliminates the hunt for product mid-build. This assembly lube is compatible with all conventional and synthetic motor oils, making it suitable for small-block Chevys, big-blocks, LS variants, Chrysler, Ford, and import engine platforms. Apply before final gasket sealing, run the engine at 1,000–2,000 RPM for 15–20 minutes, then perform an immediate oil and filter change to remove any residual assembly lube and let the fresh motor oil take over. For high-horsepower builds, competition engines, and any situation where bearing protection during break-in is non-negotiable, this case provides the assurance and convenience serious builders demand.
