Schaeffer 167 75w140 and a G80?
I took possession of a 2012 2500HD with a G80 locking differential. I would like to change the fluid out early, and I have probably three gallons of 75w140 Schaeffers 167 sitting in the garage that I would prefer to use.
Has anyone used Schaeffers with the 167? Did they play well together?
