AMSOIL Break-In Oil is an SAE 30 viscosity grade 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 ZDDP (zinc and phosphorus) anti-wear additives to protect camshaft lobes, lifters 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.

Quickly Seats Piston Rings to Increase Engine Compression, Horsepower and Torque
The primary goal during engine break-in is to seat the piston rings against the cylinder wall. Properly seated piston rings increase compression, resulting in maximum horsepower; they reduce oil consumption and prevent hot combustion gases from entering the crankcase. To achieve this, however, the oil must allow the correct level of "controlled wear" to occur between the cylinder wall/piston ring interface while maintaining wear protection on other critical engine parts. Insufficient break-in leaves behind peaks on the cylinder wall that prevent the piston rings from seating. The deeper valleys, meanwhile, allow excess oil to collect and burn during combustion, increasing oil consumption. Too much wear results in cylinder glazing due to peaks "rolling over" into the valleys and preventing oil from collecting and adequately lubricating the cylinder wall.
AMSOIL Break-In Oil Helps Seat Piston Rings
to
Increase Engine Compression, Horsepower and Torque
AMSOIL Break-In Oil's friction-modifier-free formula allows the sharp peaks on newly honed cylinder walls (fig. 1) to partially flatten. The result produces more surface area for piston rings to seat against, allowing formation of a dynamic seal that increases engine compression, horsepower and torque (fig. 2).
ZDDP Additives Protect Critical Parts from Wear
New flat-tappet camshafts and lifters are not seasoned or broken in and must be heat-cycled to achieve proper hardness. During the break-in period, these components are susceptible to accelerated wear because they are splash-lubricated, unlike other areas of the engine that are pressure lubricated. AMSOIL Break-In Oil contains high levels of zinc and phosphorus (ZDDP) additives designed to provide the anti-wear protection required during this critical period.
Increased Film Strength to Prevent Rod and Main Bearing Damage
High-performance and racing engines often use aftermarket parts designed to increase torque and horsepower. The added stress can rupture the oil film responsible for preventing harmful metal-to-metal contact on rod and main bearings. The base oils in AMSOIL Break-In Oil provide increased film strength to protect bearings from wear and damage.
Applications
AMSOIL Break-In Oil is designed to effectively break in high-performance and racing engines requiring SAE 30 oil, helping increase engine compression, horsepower and torque.
Recommendations for Seating Piston Rings
The engine builder's or manufacturer's break-in recommendations should be followed if available. Break-in period should not exceed 1,000 miles. When the piston rings are fully seated and have formed a tight seal against the cylinder walls, no oil residue will be evident on the exhaust ports.
Seating Piston Rings
When the piston rings fail to seat, the exhaust ports will have a large area of oil residue (Fig. 3). As the piston rings begin this process, less oil is passed and the oil residue area begins to shrink (Fig. 4). When the piston rings are fully seated and have formed a tight seal against the cylinder walls, no oil residue will be evident on the exhaust ports.
Other common methods to determine if piston rings have seated include performing a leak-down test or horsepower measurements over time. Break-in duration will vary between engines. Afterwards, drain and fill the engine with an AMSOIL Synthetic Racing and High Performance Motor Oil that meets builder or manufacturer specifications.
