Lucas Oil Assembly Lube Engine Pre-Lubricant

Lucas Oil High Performance Assembly Lube is a semi-synthetic pre-lubrication formula engineered to protect critical engine components during assembly and initial startup. By creating a tenacious, high-film-strength barrier on metal surfaces, it prevents damaging metal-to-metal contact before the engine's oil system reaches full operating pressure — the most vulnerable moments in any engine's life.

Key Features:

• Semi-synthetic formula with zinc, moly, and extreme pressure additives deliver maximum protection during the critical engine break-in period
• Super slick, tacky consistency clings to metal surfaces throughout the entire assembly process, staying in place until the oil system is fully primed
• Eliminates dry starts by maintaining a protective film on all treated surfaces from the moment of first ignition
• Compatible with conventional and synthetic motor oils — will not plug oil filters or react negatively with engine lubricants
• Outstanding rust and corrosion inhibitors make it ideal for long-term storage of precision engine components
• Prevents seizing, galling, scuffing, and metal transfer on contact surfaces during break-in and initial operation

Recommended Applications:

• Bearings, camshafts, lifters, and valve train components
• New engine builds and complete engine rebuilds
• Any assembly application where tension or torque is applied to metal-on-metal interfaces
• Long-term storage protection for precision machined parts

Trusted by professional engine builders, performance shops, and serious enthusiasts, Lucas Oil Assembly Lube is an essential part of any engine assembly process. Every variant in this product line delivers the same proven Lucas Oil semi-synthetic formula and protection, making it suitable for everything from single-engine builds to high-volume shop use.
