Hi All, I'm a newbie 1987 911 Turbo (or is it a 930?) owner. 39,000 miles, current gear oil not known. Which transmission gear oil to use? Do all '87 Turbo's have LSD or do I need to check that to detirmine gear oil spec? I read a bunch of the 911/915 threads on gear oil (Kendall v. Swepco), but not sure if that relates to a 911 Turbo 4 speed. I bought Swepco 201 from our host but now having doubts if it's the correct gear oil.
Thanks for your reply.
