Good value, quick ship

I understand that the break in period of a new engine is critical for the life of the engine so that is why I trusted this oil for my new sawmill engine.

I have used this in many engine. I used it to break in a 26hp kholer engine and ever since the oil stays very clean after many hard hours of work signifying that the rings are well sealed. Also I build race engines and use this to break them in. We had one motor that had to be torn down 4 times and I reused the rod and crank bearings all 4 times because they were perfect. So I got to see the bearings after about 6 different nights of racing in them and the oil pressure is excellent still. We get great ring sealing with this oil and I will always sell my motors with this oil.

Great product.

I 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.

best break in oil on the planet

Use it in 206 Briggs and world formula engines. All my engines out perform most competitors engines.

Rebuilt my engine, used this for the first time. No issues, changed after 1k mile break-in process.

Does the job I have no complaints with anything amsoil

This 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 best

Came in the mail quick, put through the fresh LS5.3 ripper and it’s still got oil pressure so it must be good.

Great 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.

Synthetic oils are superior, AMSOIL is a superior product!

No need for special additives, just buy the correct oil for the break in and the confidence is there.

Ran generator for 20 minutes then drained it all kinds of metal shavings came out. Second time ran for 45 minutes drained it not as many metal shavings came out. And put the Amsoil full synthetic in it. Run smoother check spark plug looks good and not that many metal shavings also added the gas additive run smoother than anybody’s I’ve seen on YouTube. Thanks Amsoil for an excellent product.

Third time I've used Amsoil SAE 30 Break-In Engine Oil within the last 5 years. Excellent results each time and those engines are still running strong. I've been an Amzoil user since 1975.

I used this on my 327. After priming the oiling system. Good oil pressure, no smoke, & no leaks. Going to drain it & go with Z Rod!

Great oil for breaking new engines, remmamuted motors
