I've used Swepco and Mobil 1 so far. Mobil is far better and less noisy.

Next change I plan to try Redline. Had good results with that stuff in my Laser. A guy from Redline recommended a blend of different Redline gear oils for my G50 911 and the Laser.

For the G50 I believe he recommended 1 qt. Lightweight Gear Oil (which is a 75W/80W GL-5) and the remainder 75W/90NS (has no friction modifier/additive), regardless of whether you have a LSD or not. He claimed that the Porsche ZF clutch pack-type limited slip differentials don't suffer from chatter like other LSD's do. The NS fluid also is claimed to allow faster synchronization. I believe the Lightweight Gear Oil recommendation is to help cold shifting?
