What did you do with your Z today

So with my track days and hard driving it was time. Good thing was the drain plug didnt have much of any metal shaving on it so I'm happy there.

OSG fluid is 80w 250 and I highly suggest only using there oil. My LSD has alway been quit. The only time I've heard it pop or bind is after a very long day at the track and after a few hours of cooling down it never made a peep afterwards.

But it will make the OSG LSD bind a little more. I've seen this first hand. Motul is good oil and far cheaper. But I'd rather pay $90 to change my diff being it only needs to be changed ever two oil changes if your hard on your car as I am.
