Many fine products have been mentioned and are excellent, but you can get oil and lube for all applications in our Z from Amsoil, without 'mixing'.

Just to confirm, Royal Purple MaxGear 75w90 says (on their website) that it is good for both GL-4 and GL-5 applications. That being said, shouldn't it be safe and the right thing for both MT and Diff, correct?

I changed both at the same time, early on- around 3K miles. The 6MT to make the shifting easier and the rear diff just to get any initial shavings out.
Everything has performed flawlessly over the past 2.5 years.

Just had my oil changed and I went with NAPA brand Premium Pure Synthetic. Little known fact is that they have a contract with Mobile 1 to make all their oil just stamp a NAPA sticker on it and sell it for a $1 cheaper a quart but its the same stuff. Saved some money and made a hell of a difference then the crappy stuff the dealer put in. I have heard Royal Purple is the way to go but very expensive so I was thinking of investing in it for my rear end. Is this worth the cash and also is it hard to change the rear diff. fluid? Comments please!

Does anyone know of a good site where you can buy Royal Purple in something other than cases or drums of it?

Odd coincidence. I JUST changed my tranny and diff. oil today. I went with Mobil 1 in the diff. It took a little under 2 qts. I went with the OEM Nissan MT fluid, it took about 3 1/4qts. I figured better safe then sorry(warranty). The Synchromesh seemed to be for very specific GM and or Chrysler apps. (so the label made it seem). So, I took it for a test drive after and of course the diff. felt smooth as butter(it always has) but the tranny still had what some call the "notchiness" when shifting. I doubt a fluid could change that unless its some seriously heavy shiet and that would prob. create sludge in the tranny and screw stuff up. Word to the wise get a suction gun that can hold as much as poss. That's the most labor intensive part of the maintenance.

I bought Royal Purple Max Gear 75W90, it is designed for both tranny and diff. Meets both GL-4 and GL-5 specs. Order it on-line for less than $9 per quart. Will be putting it in next week.

Since I am making the swap soon, let me ask you...
The Z 6mt tranny calls for manual or ATF?
The 350Z diff calls for manual?
MT90 is stright gear oil. What is the MTL?
Did you use a differential additive?
How many Qts for the DIFF?
How many Qts for he Tranny?

* Redline MTL: 70W-80
* Redline MT-90: 75W-90
That brought it it approximately the correct spec.
