Hey gang, going back to the thread's subject: Does Ford openly (or officially) allow the use of Ceratec now??? I hope I never have to use that crap, but if Ford guarantees not voiding the engine warranty with it, I'd be less skeptical to use it... if it comes to that (hopefully not). My 2019 owner's manual clearly says not to use any oil additives, and lists no exceptions. Unless there was a TSB, SSM, etc., stating the contrary, I'd do it only if it's driving me nuts. Ha ha. Also not addressed is if there are any potential consequences for using it with every oil change (which for me are every 5K miles).
