Which ones would you guys recommend for a 2024 3.5 boost. From my limited googling it seems like you can use either in the engine. I work in the oilfield and use my vehicle as an office so there's a lot of idling on a hot day, so would that go into your decision about which grade of oil to use? I know there's a lot of knowledge about vehicles on this board. So thank anyone in advance for any help that could be given. I haven't own a boost since 2011 and back then I had lots of carbon buildup and problem with my O2 sensors which I attributed to the idling, which I admit could be a totally wrong assumption that I made.

I watched some interesting and informative videos on viscosity and grade for oil and it led me to believe that as long as your oil selection covers the operating range of the engine with viscosity that is close to or at the recommended that you won't see much of a difference. It will flow adequately and still adhere to parts to create the film that forms the contact intermediary between the metal parts.
What you want is a catch can to keep oil and condensation from making it back into the cylinders with the recycled warm air to reduce engine carbon buildup.

0w is recommended to meet CAFE standards. It is not to protect your engine.
If you're out in the oilfield a lot, I assume we're talking rural areas so 5W-30 might be easier to find if you needed to find some.
0W-30 would be better if you're in extremely cold weather but I think we're talking incrementally better and I'm guessing you're probably not on the North Slope in Alaska.

5W-30
That's what the 3.5 ecoboost has always used and it's on the oil cap of my 2023 Expedition.
Excessive idling can absolutely wreck these engines for sure. I've seen a 5.0 crap out at about 90K miles because it had the idle hours of an engine that would typically have 500K on the odometer.

That's guys, looks like I will use the 5w-30. Like I said, unfortunately idling is just part of the job. I'm sitting in my truck many hours of the day writing reports in 90 weather. I'm just gonna get the oil changed maybe a little sooner than what is called for and I'm going to use fuel system cleaners at every oil changed to hopefully reduce the buildup in my engine.
I use 0w30 in Mrs 1ags new expy with no issues.

The higher number in the viscosity grade is what is prevailing in warm conditions. The lower number is the "winter" grade and is what is prevailing at start up, cold.
So 0w-30 and 5w30 are the same for your specific concern of extended idling in hot ambient conditions.
The ecoboost specs 5w30. Ford was smart doing this and not going with 0w20. The correlation between OEMs having engine bearing issues and 0w20 is very high (looking at you GM...)
In my opinion 5w30 covers 80% of all engine applications well.
Unless I had solid data (oil analysis, data trends on engine operation, engine tear down analysis) I would almost never go down in viscosity grade for the warm viscosity grade.
Extended idling in hot ambients would be categorized as severe service and put the oil change intervals at shorter mileage intervals than the OEM recommendations for 'ideal driving' situations.
So 5w30 and shorter oil change intervals is a good plan.
For my ford trucks, I check the manual. I put in what it says to put in and only use Motorcraft oils and filters until warranty is out. Don't overthink it.
I like your style but no need to use motorcraft products
I'd second the oil analysis for normal mileage, then adjust changes based on what the oil is telling you. Even ask the oil analysis people about the effects of your idling.
I use Blackstone out of Terri Haute, IN for my plane oil. They do auto as well.

I use Mobil 1 20k mile oil and get changed every 5 k miles with a high performance oil filter. Never had any issues at all.
I know a lot about a little, and a little about a lot.
I've used Blackstone for my truck oil; they give you a ton of data - and help you interpret it, too.
Amsoil also does oil analysis and it's ~$15 less expensive than Blackstone. I've used it for the last 2 analysis I've done with no problems.
