I recently did an ATF service on a new rebilt 01M tranny for my VW Jetta using Pennzoil Multi-Vehicle Formula ATF as a substitute for factory fill Pentosin. After reading many opinions and talking to several mechs, I began to wonder about the Pentosin ATF which has been called either a synthetic blend or a Group III. I was able to find an auto parts store that carried it for what is considered a bargain at $11.47 per quart, and was surprised to see " Chemical family: Polyalphaolefin " . Now I'm considering draining the Pennzoil synthetic blend for 5 quarts of this, especially after talking to a friend who owns a Cottman's and says that he believes the clucthes wont slide right using any other oil on this car. What you do think of that?
