We have a 2012 focus s. Dropped the ff at 2k, oci at 5k, 10k, and 15k. I used MC oil and filters and at 15k switched to PPPP. Have 3k on that oci so far and gonna go 7500 or so, depend on how long it takes to accumulate. I noticed it used a little MC over the 5k ocis, not a lot but the oil level would be right below the full hole, where it would cover the fill hole at the beginning. So far at 3k it's about the same as the MC but the engine does seem to run a little smoother.
