The iOLM on our 2017 2.3 EB Explorer always trends to 10,000 mile oil changes using a Ford spec oil which could be a synthetic blend or a conventional oil and Motorcraft FL910S oil filters. I've changed the oil twice in the first 5,200 miles, using new Motorcraft FL910S filters each time. After that I changed the oil filter with each oil change of Mobil 1 5W-30 in the 6,200 to 7,000 mile OCI's. Recently I started using Mobil 1 oil filters due to the rebates I was getting with the Mobil 1 oil. These I'm using for 2 oil changes, ranging anywhere from 12,500 miles to 15,000 miles for the oil filter. We've owned the Explorer since new and probably "over changed" the oil so I have no issue using a Mobil 1 oil filter for up to 20,000 miles.
