What are the Main Tasks of a Good Engine Assembly Lube?

AMSOIL Engine Assembly Lube is designed to avoid three potential concerns related to the building of street rod, classic car or racing/performance engines. These concerns would be:

  • Wear during the first start-up
  • Rust or corrosion during medium to long-term projects
  • Oil passage clogging or deposit creation caused by assembly lube after start-up

Adheres To Engine Parts for as Long as it Takes

AMSOIL Engine Assembly Lube is designed to be thick and tacky, so it can stay in place for months or even years. This Engine Assembly Lube is designed to stay put for as long as your project takes, so engine parts are protected when the time comes to fire her up for the first time.

Defends Dry Parts During Start-up

When a freshly-built engine is cold-fired for the first time, engine oil can take precious seconds to reach vital top-end components. AMSOIL Engine Assembly Lube’s robust formula protects parts during this vulnerable period, so your hard work and expensive engine parts survive completely unscathed.

A Barrier Against Moisture, Rust/Corrosion

As engine rebuilding projects can remain in your shop in various states of completion for weeks, months or even years, internal rust and moisture damage on engine parts is a valid concern. This engine assembly lube offers a robust anti-rust/corrosion component that protects engine parts for as long as it takes to complete your project engine.

Liquefies Once Exposed to Oil Pressure

Some engine assembly lubes can block oil passages or form deposits when exposed to heat. A good assembly lube disappears once it has done its job. AMSOIL Engine Assembly Lube liquefies and assimilates into the engine oil once normal oil pressure occurs for a few moments. This eliminates the chance of blocked oil passages or the possibility of the lube creating deposits.


Suitable for the assembly of any automotive, four-stroke engine including:

  • Passenger car engines
  • Street-rod engines
  • Classic car engines
  • Racing engines
This assembly lube protects engine parts even over very long periods. Protects from rust damage and wear during the first start-up. Dissipates into the engine oil after use.
