I emailed Amsoil regarding the information on the websites that angrybeef provided.
This is what the Amsoil Tech Services Manager had to say.
"I fully agree with this statement. and yes it is accurate. We do offer a quality
5W20 oil however if someone feels that is what they must use. Depending on the
application, our AMSOIL ASL 5W30 or TSO 0W30 may certainly be used and these are
our top shelf products."
Thanks again,
Ed Kellerman

Well, angrybeef, so far, all you have said appear to be true. I think that myself and others just needed some additional facts to be persuded to use another weight of oil not recommended by the car manufacturer. Anyway, it looks like there are synthetic versions of 5w20 that can be used that has good shear strength then the standard off the shelf 5w20 oil.

The guy at the one of the websites has read this post and is looking in to the source of the
facts posted on the website. When the guy at the website responds with his search on the source of the facts on the website, I will post them here for all to see.
