Interesting, hadn't heard about the unique oil formula so thanks for sharing. This is why as tempted as I am to run my preferred brand of full synthetic, I'm doing things by the book and putting the motorcraft in. I probably won't do my first oil change till the spring (only at 3,700 miles still, waiting till 5k). If you hang out in the maintenance/issues section too long you'll definitely get paranoid, which is why I never venture there lol. Just remember they sell ~7,500 Mustangs every single month, so out of the over 100,000 2018+ Mustangs, you see how many on the forums complaining, a few dozen tops? It's a tiny percentage. So just try not to think about it, have fun, remember the chances of something happening are very low, and worst case scenario, you have a warranty.Hmmm.... just saw a post and ford video in the maintenance section regarding a oil spec question. Watch the video if you can. So.....how about this new "Crazy Talk" theory for a Saturday morning. The knock sounds some are hearing is from pre- detonation from oil particles in the combustion chamber. The new Motor Craft oil WSS-M2C945-B1 (5W30) has a pre- detonation formula (according to ford) to help combat the detonation and so when folks immediately changed their oil to another brand (which doesn't have the mystery pre-detonation formula) many reported the car was fine until they changed the oil and now it ticks/knocks. Which leads me to ask do oil catch cans help with that as it keeps oil out of the intake or are the oil particles in the combustion chamber coming from the cylinder walls (bottom end)? I'd be curious to know if folks with catch cans who have changed oils still have the same incidence of tick/knocks or are there more? Lets not forget these are high compression engines. Back in the day 12:1 compression pistons meant race fuel and very dialed in ignition timing or the motor would grenade pretty quick. Factor in the low octane questionable fuel that some people get from their corner store and well....hmm.
As Bullitt mentioned our engines do have unique calibration with mapping that provides different low end torque (i.e. ignition timing) that regular GT's so maybe we have less (or more) to worry about. I checked the MC 5W30 oil I had ordered a few weeks ago. Its the "B1" so at least when I change my oil I'll have the right stuff in it. And I did install a oil catch can when i got the car and just checked it. It had about 3 table spoons or so in it after only 1100 miles. I gotta get off this website before I develop OCD to go along with my newly formed paranoia.
