<x-charset iso-8859-1>Hello- > Shad, thank you for your wealth of info on the oil. It is obvious that you > have lived with and have had experience with the oils of today.

There are some oilcooled engines around though... they have oiljackets in place of waterjackets or aircooling fins. > The synthetic oil is still up in the air as you will see by several > on this page that have had poor results running it.

The fact is that most of the VW industry is 30 years behind. Now, look at those pushing the frontier on new engine development... ask them what they think. > They must have a very high > warranty problem, not to mention money lost due to warranty issues.

And, the stuff I'm referencing is now, not 30 years ago. > You need the highest weight of the multi weight oil when you are starting > your engine.

It ain't happenin' in your oil pump, trust me :-). > It would be interesting if anyone that is a degreed metallurgist out their to > fill us in on case alloys and their reaction to different heats and such.

Wonder if they know that......LOL It's hard to argue with sales. If it sells, why stop selling it? BTW, before you get further into "wise-ass" mode with your sarcastic discussion, you might ask yourself whether or not you actually understand what I wrote in the previous e-mail. Do you know what I mean when I was talking about temperature vs. viscosity plots? Ever seen them? Constucted them? Anything? Ever dealt with tribology? Know exactly how viscosity factors into journal bearing equations? If not, ask questions on specific points, and I'll explain them. > I know, who cares... Me. I drive around a VW engine worth well over $20,000 as a daily driver.
