Anybody have experience with this oil for 2 strokers? Or their other products?

No, but two items regarding Amsoil.

First, my neighbor uses it and swears by it in his vehicles and motorcycle.

Second, the Amsoil guy was at the Richmond Fishing Expo and although I did not speak with him, he had many types of Amsoil for different applications.

I have not heard or read anything negative about Amsoil and hopefully some other guys will post their experiences. 

I used it a lot in my former 150 HP motor.

It is not a BIA certified lubricant, but is "recommended" by the mfg. for TCW-III use.

That may be a warranty issue for new motors.

I have questioned several Amsoil reps about the non-certification and never got a straight answer.

Availability is an issue since it is only available thru their dealer network which is like Amway, AVON, or MaryK.

I used the HP Injector.
