Break-In Oil (SAE 30)
Product code : BRKQT-EA
Designed for High-Performance and Racing Engines
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, 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
- Increased zinc and phosphorus protect against wear
- Maximizes compression and power
Quickly Seats Rings
The primary goal during engine break-in is to seat the rings against the cylinder wall. Properly seated 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/ring interface while maintaining wear protection on other critical engine parts. Insufficient break-in leaves behind peaks on the cylinder wall that prevent the 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'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 rings to seat against, allowing formation of a dynamic seal that increases compression, horsepower and torque (fig. 2).
Protects 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
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.
AMSOIL Break-In Oil is designed to effectively break in high-performance and racing engines requiring SAE 30 oil, helping maximize compression, horsepower and torque.
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 engine is new, the exhaust ports will have a large area of oil residue (Fig. 3). As the rings begin to seat, less oil is passed and the oil residue area begins to shrink (Fig. 4). When the rings are fully seated and have formed a tight seal against the cylinder walls, no oil residue will be evident. Other common methods to determine if rings have seated include performing a leak-down test or horsepower measurements over time. Break-in duration will vary between engines. Afterward, drain and fill the engine with an AMSOIL high-performance synthetic oil that meets builder or manufacturer specifications.

Amsoil Break-in SAE 30 OilI am currently having AMS provide me with a high performance built race engine for my 2010 GTR. AMS builds and tunes the fastest and most powerful GTRs in the world. I haven't actually used your product yet, but purchased it and will use it based on the recommendation from AMS to break-in my built engine using your engine break-in oil. Because AMS recommended your product, in my view your product must be the best product on the market for the break-in of high performance built race engines. Having read and reviewed your technical data for your products, it is obvious that your products are the most superior on the market.Was this review helpful?

First time using.Rebuilt my engine, used this for the first time. No issues, changed after 1k mile break-in process.Was this review helpful?
Seems greatDoes the job I have no complaints with anything amsoilWas this review helpful?
A must for breaking in a new engineThis stuff is great, I ran this in my new Harley big bore 95” for 800 miles and everything is working smooth as butter ! Amsoil is the bestWas this review helpful?
Solid fluidsCame in the mail quick, put through the fresh LS5.3 ripper and it’s still got oil pressure so it must be good.Was this review helpful?
360 FE rebuiltGreat product. First used to break in solid lifter cam, the moves can over to rebuilt motor and used to break I. Piston rings. Great product. I’ll be using it again on my 289 when it’s complete.Was this review helpful?
Excellent protection for new engines!Synthetic oils are superior, AMSOIL is a superior product!Was this review helpful?
