Wife just got a 2015 Kia Sedona with 60k miles on it. She bought pre paid maintenance for 2 years from the Ford Dealer. 5W30 Motorcraft SB every 6 months or 5k miles. The manual says to use an A5 rated oil ever 7,500 miles but if A5 isn't available then to use API SL. I will be deployed so I won't be home to maintain it. Obviously M1 EPHM would be better as it wears the A5/B5 spec. Any problems with using the MC SB while I'm gone for a few oil changes? That's what Ford uses in their Ecoboosts and they get good results so ithink it will be fine?
