Amsoil in 986?? Anyone using it?

[c-c]

A friend of mine was a Ferrari mechanic and talked me into using this on my shovelhead (40wt racing oil). Says it extends the life of the engine and was amazed at how clean the engines were after using Amsoil.

I have had great success in my old shovel, runs cooler and always comes out clean.

Wondering if anyone has used it on a boxster.

thanks -c
