argyle Posted August 31, 2018 Share Posted August 31, 2018 Brand new 2018 MKC... at what mileage/kms is the best for the first oil change ? With the new engines and oils currently, I've been told differing numbers. Thank you in advance. Quote Link to comment Share on other sites More sharing options...
jcartwright99 Posted August 31, 2018 Share Posted August 31, 2018 I'm a big believer in 1000-2000 mile first oil changes. I am an oil nerd though (I can admit that). If you are going to use Motorcraft oil, I would do 5000 mile oil changes (maybe 6 with full synthetic). The Ecoboost engines with turbo and DI are hard on the oil and bring some unique issues to deal with. I would only use a Dexos1 Gen 2 oil at this point, especially if you want to go over 5k OCI's. Ford did recently change some of their certifications but I don't know enough about it yet. Quote Link to comment Share on other sites More sharing options...
