I've been spending way too much time trying to figure out what type of 90 wt oil to use in the differential. It seems EP qualities are a must, but I'm unclear about concerns that these additives will harm yellow metals. Are there any brass or copper components in the differential to be concerned about? If not, then GL-4 or GL-5?
