It now seems to be common to find fluids that are rated both GL-4 and GL-5. Having said that, I use both GL-4 (transfer case) and GL-5 (differentials) in my truck.
At the moment, I purchase different fluids for each. Would it be wise to stick with what I'm doing, or would it be a better option to just go for the dual rated oils? Thanks!
