 | BREAK-IN OIL (SAE 30)AMSOIL Break-In Oil is an SAE 30 Oil formulated without friction modifiers to allow for quick and efficient piston ring seating in new and rebuilt high-performance and racing engines. It contains zinc and phosphorus anti-wear additives to protect cam lobes, lifter and rockers during the critical break-in period when wear rates are highest, while its increased film strength protects rod and main bearings from damage. AMSOIL Break-In Oil is designed to increase compression, horsepower and torque for maximum engine performance. |
BREAK-IN OIL VS REGULAR OIL
Regular motor oil (synthetic or conventional) is designed to prevent wear. Break-in oil on the other hand allows the rings to wear down the peaks on the cylinder wall to form a good seal
WHY IS BREAK-IN OIL IMPORTANT
Although a freshly hones cylinder wall appears to be completely smooth to the naked eye, it actually contains sharp peaks and deep vellys that prevent the rings from seating fully. The formulation of AMSOIL Break-In Oil allows for controlled wear of these peaks and valleys to ensure optimal ring sealing. Improperly seated rings lead to oil consumption and power robbing blowby
PROTECTION FOR FLAT-TAPPET CAMS
Correct engine break-in is also critically important to flat-tappet cam shafts. Because they wear faster than a roller cam, flat-tappet cam shafts need to be seasoned or hardened via the break-in process.
An improperly broken-in cam shaft can suffer from flattened worn tappets and lobes. Worn tappets and lobes effect lift and duration thereby reducing power and efficiency.

CONTAINS ZDDP FOR CAMSHAFT PROTECTION
AMSOIL Break-In Oil is specially formulated with ZDDP (Zinc and Phosphorus anti-wear additives) that are head activated. This is what allows a high level of protection for the cam lobes and rockers yet also allows for correct cylinder wear/break-in.
A common amount of ZDDP in break-in oil is 1000 ppm of ZDDP. AMSOIL Break-in oil is formulated with 2000 ppm of ZDDP

WHEN TO USE BREAK-IN OIL
High performance, race and competition engines, whether a rebuild or new crate engine should use break-in oil. If it's a crate engine, follow the instructions that came with the engine. If it's a rebuild, your engine builder can guide you on the break-in procedure.
If you've just purchased a new car or truck, it doesn't require break-in oil. It's best to simply follow the manufacturer's recommended break-in procedure (typically require you to drive under light-to-moderate load for a few hundred kilometres) then change oil.
