Yes it just has a friction modifier in it.

I did this on Saturday. Great write up! Super simple, no pics necessary.

Sweet! Thank you for helping me get rid of this slight anxiety.

Put some Red Line in there.

I've changed my rear diff oil three or four times now over the past 3 years. This past swap, the oil looked pristine while draining out. Compared to how terrible it looked the first few times, I'm not sure what that means...

You're getting older and slowing down?

Is Red Line 75W90 GL-5 Gear Oil is correct for 370z Automatic drivetrain for diff fluid? I read the whole pages in this thread but I had to ask to double check to confirm. This is not for transmission flush, only for diff if you are asking.

Thanks guy.

Can the differential change be done by backing up on Rhino ramps, or is it necessary/better to jack it up, and place jackstands to keep the car level ?
The ramps & jack I have, the stands I would need to buy.
Thanks

I had just the rear end jacked up and I thought everything had come out and just to satisfy my curiosity I jacked up the front while the rear was still lifted and another pint poured out. I would recommend the whole car be level when doing this.

anyone try royal purple max gear? my autoparts store dosnt carry the redline, so i think i will try the barney blood.

jetguy · 06-21-2012, 02:27 PM

Do I really need two of the gaskets: [38351B] WASHER for the oilswap ? My Z has 10k miles.

jetguy · 06-28-2012, 09:33 AM

I say no. they are just solid metal washer. i just added a few ft/lbs when i tightened them.
