I'll offer my $0.02 here. Use only the Porsche lubricant, which is a shell product, or this Mobil 1 product

Anything else, and you will have issues with synchros. This is especially noticeable with the 6 speed. As stated above, these are transaxles, not transmissions, and the inclusion of the trans + the dif in the same housing requires some unique properties for the lubricant. Swepco was great for the old air cooled boxes, but I don't think it works well with the newer cone type synchros in the latest cars. I may be wrong, but I've had great results with either of the above two lubricants.
