I know it takes 75W-90 I want to upgrade from factory fill to amsoil severe 75w-90. What gear oil are yall running. I don’t track the Nismo just street driving and occasional spirited driving on the road. And sharing the pump I’m gonna get to do all this seeing how I gotta do it on the garage floor. What are y’all thoughts??

I use Redline 75W-90 along with a pump that screws onto the jug (I currently have these 3 on jugs in my garage):

Easy DIY job laying on the garage floor. Back up onto ramps if you have them, otherwise jackstands are fine. It's important to keep the vehicle near level. I personally back up onto ramps then jack the front up to level it out.

Plenty of room under there for the jug/bottle w/pump. You can see the drain in my 2nd pic; fill bolt is on the driver's side of the case. 10mm hex bit is needed for the fill & drain.

Amsoil SG is a great gear oil as well, I've run their products in one of my Jeeps when Redline was back-ordered. You can't go wrong with either product. The pumps I linked above will fit the Redline gallon jugs and the Amsoil quart bottles.

If you end up with the Amsoil EasyPack squeeze bag, you'll need a small rubber tube instead of a pump to put on the nozzle and snake up into the fill hole. I used this method to fill my Grand Cherokee front differential twice, using the below 1/4" clear fuel line:
