Assembly Lube 4oz

Lucas Oil Assembly Lube 4oz is a semi-synthetic engine assembly lubricant designed specifically for engine assembly tasks, including initial startup and break-in procedures. This high-performance lubricant is ideal for those performing engine rebuilds or freshening long-blocks, ensuring optimal protection during critical moments when oil circulation is not yet established.

The semi-synthetic formulation of this assembly lube clings effectively to metal surfaces, creating a protective film that resists washdown during initial cranking. This characteristic is essential for protecting internal engine components such as valve train assemblies, crankshaft journals, and piston skirts, ensuring they are well-lubricated during the crucial startup phase.

Engine builders and mechanics will find the 4oz bottle format perfectly sized for a single engine rebuild, allowing for precise application to critical surfaces. This compact container weighs 0.29 lbs and fits easily in any tool bag, making it a convenient addition to any mechanic's toolkit.
