I always use conventional green coolant in my 6.9, which has a couple of pinhole leaks in the radiator and now needs to be filled. That conventional green is a little hard to find out here, though, and I need to add coolant without making a long trip right now. Is there any reason not to use Peak Universal 50/50? It seems to have the same ingredients as the conventional green - ethelyne glycol, water, diethylene glycol, and denatonium benzoate - in roughly the same proportions.
