I've googled this and getting a lot of mixed answers and just wanted to make sure I could, got some 75w85 Nissan mt transmission oil , Nissan OEM Manual Transmission Fluid MTF 75W85 - 999MP-MTF00P (http://www.thenismoshop.com/Nissan-OEM-Manual-Transmission-Fluid-MTF-75W85--999MP-MTF00P_p_310.html), and saw that the grade of gear oil was also the same, could I use it for my clutch pedal oil Yai or nay?

You talking about differential gear oil? Diff oil usually has more additives specific for diffs. Personally, I wouldnt put diff oil into a Nissan transmission since transmissions can be finicky.

Clutch pedal oil wtf? I sure hope you aren't filling your clutch master cylinder reservoir with transmission fluid lol...

I have Amsoil GL4 75W-90 in my transmission... AMSOIL Manual Transmission & Transaxle Gear Lube 75W-90 (http://www.amsoil.com/shop/by-product/transmission-fluid/manual/manual-transmission-and-transaxle-gear-lube-75w-90/?page=%2fstorefront%2fmtg.aspx)

And I use Amsoil Synthetic 80W-90 gear oil for my VLSD... AMSOIL Synthetic 80W-90 Gear Lube (http://www.amsoil.com/shop/by-product/gear-lube/synthetic-80w-90-gear-lube/?code=AGLQT-EA)

If you mean the fluid in the reservoir by the brake reservoir, it takes (like the brake, as one might guess) DOT4 brake fluid. If you put oil in it, the best case scenario is that it won't ruin things..... but it probably will, and you'll never get it flushed right.

Gear oil goes.... on the gears. The actual transmission, filled either from under the car or through the shift boot, takes GL4 gear oil.

Again, never put oil of any sort in the brake or clutch hydraulic reservoirs, ONLY brake fluid.

Transmission fluid use gear oil
Diff fluid use gear oil
Power steering fluid use ps fluid OR auto trans fluid
Brake fluid use brake fluid
Clutch master cyl fluid use brake fluid

trans oil gl4
diff oil gl5

gl4 is yellow metal friendly. gl5 has more sulfur additives and will eat up your trans, but is safe for use in the diff
