FHS Oil’s Full-Synthetic Assembly Lube is engineered for engine builders who demand the highest level of protection during the most vulnerable phase of engine life—assembly and initial fire-up. Whether you’re building an engine from scratch, completing a rebuild, or performing precision maintenance, this advanced liquid assembly lube provides exceptional lubrication, protection, and reliability.

Unlike thick, tacky paste-style lubes, FHS Oil’s assembly lube features a liquid, heavy-viscosity formula that flows, coats, and clings without clumping. It delivers a durable lubricating film that shields vital engine surfaces from friction, wear, and corrosion while allowing for smooth component movement and proper seating.

Key Features

Enhanced Wear Protection: Heavy, durable film minimizes friction and wear during initial startup.
High Adhesion: Clings to metal surfaces to provide reliable protection throughout assembly and rotation.
Corrosion Resistance: Guards against rust and corrosion during storage or pre-fireup periods.
High-Temperature Stability: Maintains lubrication under extreme heat and load.
Liquid Heavy-Viscosity Formula: Easy to apply, evenly coats surfaces, and avoids the mess of paste-style lubes.
Engine-Builder Approved: Ideal for racing, high-performance, and precision engine builds.

No matter the application—street, strip, or off-road—FHS Oil Assembly Lube ensures every build starts strong and performs at its best.
