Excellent material !! (re: post 48) -and considering that article in Machinery Lubrication was over 17 years ago, I'd have to think that base oil development is even further advanced today. It would be great to see them update that article !!
Regarding post #54, your statement "--racing oil is in no way comparable to standard passenger car oil" is so totally true, and certainly a fact that we should always remember. Granted, it is very interesting to learn what they are using, which is certainly critical to their success, but you are totally correct that our standard passenger car application is so extremely different, which at the very least requires an entirely different additive package. But it does make interesting reading, none-the-less.
I have always found the articles on the Machinery Lubrication website very interesting. -thanks to all who share them.
And thanks to each person on this BITOG website who takes the time to make useful, decent, responsible replies.
