Well, of course he recommends Schaeffers but I still use Mobile 1 which he says is great. But I have already ordered a case of His synthetic oil. I do computer work on the side for him in exchange for automotive lubricants. They sell all kinds of lubricants (automotive that is). They have a great penetrating (automotive) lubricant that kicks the shit out of anything else I have used. They put all of their money into R&D instead of advertising (which is why i had never heard of them). They sell to big corporates such as Good year and firestone for all of there test vehicles. Most of their client base is commercial carriers and race team. They seem to have some great racing products too. We'll see, I don't like switching lubricants so I will stay with mobile 1 on my coupe and Castrol syntec in my Maxima but I am going to try the Schaeffers synthetic in my CRX once I get the block back. The degreaser works great also.
