Breaking in a '16 Focus ST 2.0l Turbo

[PFP]

Whatever you do in terms of leaving in factory fill or changing it, I suggest using low NOACK synthetic (certainly less than 10%) in the long term because you have direct injection and will be prone to carbon build up on your intake valves from excessive PCV blow-by. Pennzoil platinum and Mobil 1 have very low NOACK. the PQIAA website can give you a list of oils for comparison.

Valvoline Synpower w/MLT shows 9.3% for 5w20, 10.2% for 5w30 and 6.3% for 10w30. Valvoline Synpower shows their 5w20 and 5w30 to have Noack of 10%. I don't believe PP is this low anymore and Mobil 1 doesn't post Noack numbers in their TDS as far as i know.
