Alright, I realize it's only surface rust, but I will only buy and install coated rotors from now on...I was thinking (probably more so hoping) that DFC daily driver rotors would also be coated in some fashion to retard rusting, but they aren't and for only 10 to 20 dollars more for a full set of rotors, it's worth it to me to go coated just for the better rust-free appearance. Live and learn I guess... Greg

I went 273k mi. with out changing the brakes and they were fine when I traded in the car. ? Paul

In fairness to your dealer, Ford does specify a 12 month oil change interval, in addition to the 10K mile alarm. In a hybrid, neither has a place. I did oil analysis throughout C-Max ownership. The data's attached. One change is early, at 12 months, and the last is extended to 2 years. There is a pattern of low and high water in the oil, with associated flash point depression. It is purely dependent on recent driving; after 100 miles at highway speeds, there's very little water in the oil. That's not true after a large number of short, low-speed trips where the ICE never gets hot. Ford has changed their tune. My new Escape will get ~15K miles on this oil change, because the Escape algorithm uses ICE on-time. Bov Oil Data 191105.pdf
