Friction-modifier-free formula helps rings seat properly for maximum compression and reduced blow-by. Excellent film strength and proprietary anti-wear additive package help ensure cams and bearings are protected during break-in. Delivers competition-quality engine preparation.
Purchased a new Generac 15.5 Kw generator for our hurricanes. Knowing that Amsoil is the pioneer of API rated synthetic motor oil, it was a no-brainer to go with their Break-In Oil to start protecting my valuable asset from the start. I plan on moving to the Amsoil Small Engine Oil after the break-in time has been met per Generac specs. Looking forward to a long reliable enginge life to support my emergency needs if required.
This product is the best oil anyone could ever need for breaking in a newly rebuild engine. It has the right makeup to ensure that all parts are lube in the great manner.

So i went with the break in oil and i was not disappointed. the oil filter combo went the distance of the break in. for my Equinox this was 500 miles. zero metal flakes after the first change. the oil still had a nice red color and everything is sealed up and broke in so smooth. they got me to total seal compression. i am 100% happy as this is my first use of a complete Amsoil from New Engine day 1. i will not ever use another product again. Amsoil has a new life long customer!!!! keep it up. i am one of many who understands Amsoil is the way to Go now.
Only break in oil i will use in future builds rings set perfectly compression is on point Highly recommend !
Bottom Line
Yes, I would recommend this to a friend.

Amsoil SAE 30 Break-In Oil: Great Gear for Gearheads, Not Everyday Drivers
As a gearhead who recently rebuilt my engine, I wanted the best possible break-in for optimal performance. That's why I opted for Amsoil SAE 30 Break-In Oil.
I bought this break-in oil because of the high-quality reputation of Amsoil. My online order arrived on schedule and in great condition.
I did have one question which was answered super fast via email.
Easy to see. Works as advertised. Good price. Highly recommended.
Bottom Line
Yes, I would recommend this to a friend.

BEST BREAK IN OIL, PERIOD!

After recently wiping out hydraulic flat tappet cam and lifter sets using parts store oil with zinc additive, I switched to Amsoil. I've since broke in two SBC hydraulic flat tappet engines with Amsoil. Everything broke in the way it should. I will never go back to store bought oil and additives for engine break in. This stuff works!! Don't cheap out on your investment with cheap oil, especially when breaking them in!
