Rear end oil/fluid recommendations

[Nite Moves]

Im eventually going to change the rear end fluid in my 81/4 rear. I was woundering what is a good product to use and weight. Any help is welcome on this. Daily driver. Thanks

Just in case you have a sure grip they use an additive.
If not, any personal choice of gear oil is fine.
