Replace blue stuff now?
My '14 Monogram had 29K on it when I bought it three months ago. I have no service records, so I'm about to change out tranny and diff fluids. I changed oil to Mobil-1 5W30 and installed a Fumito drain plug. I think I saw in the manual that the coolant is good for five years, but it seems prudent to me to flush and change now. I see now there's red stuff that is supposed to be better than blue stuff. Anyone know anything about that?
