In the past, I have always ran strictly Motorcraft fluids, filters, and when ever possible, all replacement parts. With the Diff oil I would just go ahead and use motorcraft brand in the weight specified in your manual. Whatever the price diff is, you only change the diff oil out once in a blue moon. The price of the fluid is not too important.
As far as engine oil, like others have said, you can't go wrong with Motorcraft brand 5w30. Either Synthetic blend or full synthetic. I ran the syn blend motorcraft in my previous 2012 3.5 ecoboost and had no issues what so ever. The only place that I could get full syn motorcraft around my area was if I had the oil change done at the ford dealership.
That being said any oil with the Ford WSS-M2C946-A certification will be fine to run in you engine and will not void any warranties.
I traded my 2012 eco in last month on a 2018 and I want to go full synthetic on this truck. I plan on either using Mobil 1 EP 5w30 or Pennzoil ultra platinum 5w30, since like I previously stated, I do not have access to motorcraft full synthetic. Both of these oils have been proven to be reliable choices and will be good options for you to run in your truck.

Edit: It appears that mobile 1 5w-30 does. https://www.mobil.com/english-us/pas...xxmobil-1-5w30
Although, apparently my 2018 owners manual states WSS-M2C946-B1 as the specification. This is confusing! It seems that mobile 1 5w-30 does not meet WSS-M2C946-B1.
Valvoline apparently only lists it as a "recommended application" not as "meets or exceeds" https://sharena21.springcm.com/Public/Document/18452/f1d157d1-0f7e-e711-9c10-ac162d889bd3/3aa410a1-0bbd-e711-9c12-ac162d889bd1
Does anyone know oils other than Ford that meet WSS-M2C946-B1 without costing an arm and a leg?

It's amazing. Some on this forum will tune their engines out of warranty, modify the suspension/tires to the point of being dangerous (if not illegal) and out of warranty, Install aftermarket lights that might be dangerous (if not illegal) and out of warrant, FORScan various system parameters out of OEM spec, modify the infotainment system out of OEM spec, etc., etc., etc., and then act like it is sacrilege to even discuss an alternative lubrication strategy even if someone is trying stay within spec or even surpass it. Past bizarre.
Hang in there kehyler. Don't let them get to you.

Another useless post that speaks volumes.
He never said 0W30, even if he had one would think that you (and everyone else) would be smart enough to know what he meant. I'll admit changing your oil a 1K isn't overkill. lmfao.
No, I'd say it's only obvious to you.
Another really helpful post.
And another one that really makes sense. lol
Amen.
kehyler: Nothing wrong with 5W-30 Mobil 1 Synthetic. If you would have asked about an oil filter I would suggest using the Motorcraft filter made for your engine. Haven't looked up the rear diff oil but staying with the recommended oil and weights Ford recommends would be what I would do.
More times than not, same 'ol know-it-alls and there clever responses that try and ruin it, can't just try and be helpful or even better, just stay out of it.

Correct. Quality products are fine, but you should use the Ford recommended weight... 5W30 in your case. Not 0W30.
I'm all for overkill... but the rear end is just about bulletproof in these trucks, short of infant mortality or insanely stupid power application or driving. I would hazard a guess that you will run a bigger risk of having leak issues from cracking the diff cover than you will from any "break in" metals that might be present. I get it - I still dump the factory oil at 1K myself. But the rear end? That's serious overkill.

If the post you partially quoted did not sufficiently explain why, then that in itself (combined with responses to others) substantiates that further detail would be a waste of energy.
Seriously: It's obvious to anyone reading that you are looking for an oils debate. Not biting, you need way better bait to reel me in.

What's a 2018 2.7 Ecoboost cost? $40,000 on the low end? You're probably still paying hundreds per month if you financed it. Now you're going to risk a big repair bill by going a few dollars cheaper on an oil change. Even if the oil change cost an extra $50, spread over 5000 miles it comes to $0.01 / mile more. A penny per mile more and you're risking your dealer refusing repair because you saved a few pennies on an oil change. It makes no sense.
It will probably be fine. But it's a question of risk. You probably did not buy an extended warranty either did you? Because it costs a few dollars more per month. On top of your hundreds per month finance payment. Risk/reward is the key.

Hmm. OP is expecting a reasonable response to an unreasonable question. If someone asks me, "is it safe to eat a crayon?" I am going to ask them why they want to eat a crayon, not answer them that indeed you can eat a crayon safely.

That's helpful. Any chance you know of a list of oils that meet such certification?

Stick with Motorcraft, Mobil 1, or any other reputable brand name and you will be fine. As long as you are changing within the recommended intervals and using the proper viscosity rating you have nothing to worry about.
