Were you having a problem with oil use/consumption and were you having to add oil on a regular basis? How many miles did you have on your Maverick, when was your last oil change?

Even though it needs an oil change, I did added a half of quart of 5/30 weight oil at 28,000 miles ( 32300 miles current) and basically I’ve been checking my oil usage and around 7,500 miles the oil level would be a half of quart low. Is that normal for a recommend 10,000 mile oil change. What’s really my concern is that service record from the Ford dealership , I was reading that the first two oil changes, the oil weight was 5/20 and not 5/30 weight. The last oil change used 5/30 , that shouldn’t be an issue of using the two different weights . Have any one else notice of the oil weight the dealership uses?

In my opinion 10,000 is way too long of an interval.
5w-20 should not be used in gas engine with a turbo and is uncommon. 5w-30 is more the norm. Some dealers will push what they have in stock, not cool.
Honda and Toyota are using some crazy thin oils in some of their latest vehicles.

I wonder if the explosions were the tires blowing from the heat. Also, was the oil fill cap missing or loose - that might explain oil all over the underside of the hood.

No offense, but adding oil and continuing to drive as it was leaking is a bit like me trying to stop a raging campfire by throwing gasoline on it.
Like David Bowie sang “putting out fire with gasoline” RIP David.
“Fixing oil leak by adding oil” RIP Maverick

As said by others, so thankful you and family are safe!
I have an EcoBoost also and while what happened to you is terrible, the "silver lining" may be that this is proof the 10,000 mile oil change is unacceptable given from what I have read here and in other threads (1) turbos need clean oil and (2) turbos cause fuel to mix with the oil and dilute it which is why the EcoBoost needs 5/30 not 5/20. Given your "change oil" light came on and if it is calibrated at 10,000 miles and you were traveling thru mountains and probably putting a strain on the system and you were at 10,000 again, everything overheated etc and ....
I agree with a previous poster ... don't care what the manual says, I will change oil 3 to 4 thousand, especially when it is summer and really hot under the hood.

Pretty sure this was detonation causing a major, catastrophic failure.

I doubt the dealership used anything other than 5w30. The OP is probably mistaken, or if it's typed on the service work order then I would suspect a typo. I doubt they even have 5w20 on hand. (EDIT: it has been pointed out to me that non-turbo Fords often do use 5w20, and if that was actually used, it certainly wouldn't be healthy for the engine but it wouldn't fail right away. Still betting on octane. (y))

I noticed the OP is still answering questions but didn't answer mine about octane and if he fueled up at high altitude. I ask this because I believe the beginning of the end of my last vehicle's engine, a 2017 Mazda CX-9, was 85 octane fuel purchased in Copper Mountain CO. The Maverick (and every Ford ecoboost engine) states not to use any fuel below 87, and I run 91+ all the time anyway, as it's rated for 250hp with premium fuel. My Mazda drove fine on that trip, but a few weeks later had a blown engine. Probably had some detonation but nothing I noticed and certainly not any damage sufficient to spray oil underhood.

The main reason for oil getting diluted with fuel is the GDI fuel injection on most turbo if not all turbo engines. This is because of poor mixing on especially cold start ups. The good or bad thing is that if you let the oil get up to temperature the fuel will “burn” off from the oil. Short trips add to the dilution problem. This is one reason for port injection being used with direct injection. It is much better for light load performance, GDI kicks in when things get serious.

Under normal circumstances I'd agree with you but, if you recall, the OP noted that there was no cell service at the location of the initial failure.

Now he's got a judgment call as to whether he stops driving and sits on the side of the road until someone capable of getting help comes along or tries to nurse it back to a gas station he know was there.

I don't know if I'd have made the same call but I wasn't there, don't know the location, and it wasn't my kids and wife sitting there so I'm not sure it's appropriate to criticize the call he made. I just hope he comes out of the experience whole.
And the gas station doesn't have a phone?

Yes. Or any other number of remedies. It's hard for the OP to hear but a great warning or reminder for everyone else. A lot of things can cause a check engine light and some of them are not a big concern. But any kind of engine performance issue is an instant park-it-and-stop-driving event. Oil spraying under the hood honestly should be extremely obvious that you should not drive further. It doesn't matter if the vehicle is insured, under factory warranty, or not.

There is never a good reason to drive an engine until it seizes and catches on fire. Well. Maybe zombie apocalypse.. but otherwise, if you're not actually going to die, don't ever do this.

A friend of mine who is a bad ass mechanic had some free oil changes with the purchase of his new Nissan Frontier. That year Frontier uses 3w-30. The dealership put 5w-20 in it. The dealership said they didn’t stock 5w-30, BS. I couldn’t believe he was okay with that except for the fact that he is very tight with his money. Most non turbo Fords use 5w-20, my 2019 F150 takes 8.8 qts of it.

And I guess they had no mechanic at this rural station, no tow truck, and was the only building within a mile. No other locals willing to call a tow truck who are pumping gas either. Yep, makes perfect sense now. He was in the Twilight Zone.

Half of Fords on the road require 5W20, why would a Ford dealer not have it?

His original explanation noted that he didn't think a tow truck could get positioned to load his Maverick at the gas station, which is not where the problem began, so he went to the parking lot. None of us know what he was seeing, so why all the Monday morning quarterbacks?
