Rear End Oil Change

[KIRK343]

I recently had 4:10's put in my MM. I've put about 500 miles on it and the mechanic suggested that I change the oil. Can anyone recommend a specific type/brand for me to use?

I use royal purple 75w/140 no modifier needed with RP

Redline 75/140w, no friction modifier needed.
