[QUOTE="GreenF350, post: 451460, member: 7731"] Didn't know the 6.7's used coolant additive. I would imagine it is the same SCA that they all are supposed to use then, in which case you can get a bottle of test strips from your local autoparts store and check it yourself if you want to be sure. I would guess that it is fine with the miles you have on it, but who wants to guess with a $50,000 truck? -Aaron [/QUOTE]
