thanks for the help guys.
I dont have one but I have worked on one. I just stated that because I know that Mobil 1 is nothing more than synthetic gear oil as opposed to our special V160 oil which I heard is actually dextron ATF.^I've heard success stories with Amsoil, Royal Purple, and Redline. I don't believe it will have any negative effect on the tranny. What model year 911 Turbo do you have?
Great, I just needed to know because it's always difficult to give proper advice without all the facts. To begin you won't find that product you want in the size you want at just any local parts store. It is safe to use a Redline synthetic of the same weight, shifts will probably be smoother for a while until the effect is gone; it will feel like the Mobil after a while. The way I was taught this is not recommended, only because I only find a lot of hearsay on the matter.2002 6 speed.
I still can't find any Delvac Mobil 1 75W-90.
