I have always ran Mobil 1 gear oil 75-90

 

Go with Neo RHD 75w90 this next go around.

 

to be honnest you better go with Amsoil severe gear 75-110 thats maybe the best oil for hard abuse

 

I have no idea what that means. But I do run the SOS twin disc.

 

I know you run a SOS twin disc from your posts about it. Side stepping = dumping the clutch.

 

ouch! what a mess. i am jelous you are getting a puddy diff. i called about it, was more then i wanted to spend for piece of mind. if mine had broken i would be more inclined. as for fluid. puddy will prolly reccomend a thick fluid with a stabilizer that turns it into a heavy honey fluid lol.

 

Just received my Puddymod diff. Instructions from Ben / Puddy:

"Use a good quality GL-5 Hypoid 75/140 gear oil in the rear. Use this oil in the rear for 500 miles then drain.

Use Amsoil, Motul, Valvoline, or Mobil1 75/140 gear oil every 12K miles."

 

^^^^
Yup that's it. I've followed his directions and haven't had any issues.
