This is one of the best oils around. The additive package is second to none. Talking to them at the home office is like talking to a friend. aaaahonest beyond belief.It is almost hard to believe that such a company still exists. If you have a new car keep in mind they do not have API listings. That could cause you grief during warranty.Redline is costly and you have to take this point into account, but with them you have an add. package that makes the cost ok I think.Check to data page out.Wow you have to be impressed.

I have used there transmission and motor oil for a long time now and often take my car to track events it alows quick shifts and and smooth running clean engine.
