We bought a used 2015 Kia Sedona back in May. The first oil change was 4k miles long with Motorcraft SB 5W-30. It used about half a quart in that time. The second oil change has about 5k miles on it with Motorcraft FS 5W-30 and no oil consumption. Could this me NOACK related loss on the first change? Any ideas? It looks like this engine needs FS to avoid oil consumption. I was planning to use the SB in it and call it a day. I always though Moly helped prevent oil consumption which was the main reason I picked the SB I did. What would you do from here? Motorcraft Synthetic is expensive so once I get home from my deployment I'll be switching. My wife likes the Ford Quick Lane oil service while I'm gone so probably will keep with that till I get back. Though I'm curious how PYB would do. Might try to get her to take it to a Dodge dealer next change.
