SAE 30 Break-In Oil
AMSOIL SAE 30 Break-In Oil — break-in oil for a new or rebuilt engine. Without friction modifiers so the rings seat quickly; with a high dose of ZDDP it protects the cam lobes and bearings.
Description
Break-In Oil is a special oil for the first hours (break-in) of a new or rebuilt engine.
The friction-modifier-free formula lets the peaks of a freshly honed cylinder surface partly level off, so the rings seat quickly and well: compression increases and gas blow-by into the crankcase decreases (blow-by).
Main specifications (manufacturer's data)
- A formula without friction modifiers creates more surface for the rings to seat
- Creates a dynamic seal that increases compression, power and torque
- Contains high levels of zinc and phosphorus (ZDDP) additives
- Protects splash-lubricated parts excellently — the camshaft and lifters — during break-in
- Increased film strength protects the connecting-rod and main bearings from wear
When to use
- For breaking in a new or rebuilt four-stroke engine, including racing engines
- After break-in, fill the engine with a high-quality synthetic oil that meets the engine's requirements
The specifications are AMSOIL's official data. Before use, read the instructions given on the packaging.
