You bring up lots of questions that I can not answer. I can point you in to someone who might be able to answer your questions.
Go here and fill out the form with your questions and let us all know the reply
To clear something up from earlier threads. I am a dealer/distributor of AMSOIL. I do not pay AMSOIL to link to my web site. I receive a commision from any sales generated from my web site. I am a little confused as why you would think that they would.
I will admit that I do not know everything about all the AMSOIL products since I am a new dealer.
As I said before you bring up some interesting questions that I would like to know the answers to. Maybe together we can find them.
