Lucas High Performance Engine Assembly Lubricant 4oz

Lucas Assembly Lube (4 oz) is a high-performance, semi-synthetic assembly lubricant from Lucas Oil, engineered specifically for engine builders, mechanics, and technicians. This tacky, super-slick formula provides critical protection during initial engine startup and break-in periods.

Designed to pre-lube vital components like bearings, cams, lifters, valve train, piston skirts, and other metal surfaces before assembly, it prevents dry starts, seizing, galling, and scuffing—ensuring maximum protection when oil pressure hasn't yet fully circulated.

Key features and benefits:

• Contains zinc (ZDDP), moly, and other high-pressure additives for superior anti-wear protection during break-in
• Clings tenaciously to surfaces for long-lasting film strength
• Mixes completely with any engine oil and won't plug filters
• Acts as an excellent rust inhibitor, ideal for long-term storage of parts or assembled engines
• Useful as a torque aid or anti-seize for bolts, nuts, and fasteners under tension/compression

Easy to apply (often with an included applicator tip in the bottle), this 4 oz bottle is a go-to choice for professional engine rebuilds, performance builds, and anyone wanting to eliminate startup wear risks. Trusted by engine pros for reliable, no-compromise protection right from the first turn of the key.
