Can I use 0w-40 in my Raptor?

I recently bought a 2019 Ford Raptor with the twin turbo 3.5 ecoboost engine. While 5w30 is noted in the owners manual, I’m thinking about switching to Mobil 1 0w40. From all that I’ve researched, the 0w is better for the turbo by getting oil to them faster. The 40 provides better protection for a hi-performance engine, which the 3.5 is at 450 horsepower.
It just seems like a better thing for the engine overall. Am I wrong, or overthinking all of this??

I would be using 0-40 or 5-40 in that engine. Do you have any data on potential fuel dilution?
 
Should not be a problem.

2025 350 Transit has basically the same engine, will go Amsoil SS 0W-40 when conversion complete

2019 Tacoma Amsoil SS 0W-40 runs awsome

2017 Honda CRV 10W-30, see how that fuel nuclear bomb does on Amsoil SS 10W-30, may switch to Amsoil SS 0W-40

No, sorry. I know that when I changed oil last time it smelled like oil. I had a big block Chevy and I could smell gas when I drained the oil. Not very scientific I know.
 
I've been using M1 0w40 in my 2013 3.5 ecoboost for a few years now. I wanted something thicker to help protect the timing chain and turbos.

Make sure you use a good quality oil filter and change your oil at 5k miles or earlier.
 
145k kms on my 2016 using Edge 0w40. Use it. I would still change it at 5k intervals due to soot buildup with the direct injection.
 
I’m opting for the Mobil 1 0w40 euro, api certified. I use the Mobil 1 filters.
I’m old school and remember my dad using Kendall 2,000 mile oil and changing it at 1,500 miles. Ha
My plan is to start looking for a nice day at the 3,000 to 3,500 mile mark. Overkill? Sure, but oil is cheaper than an engine.

Amsoil SS 0w40. Initially I went with 30 but exchanged it for 0w40 when this happened to me after ............................

Nothing, just a little heavy-footed driving on the Interstate. 229 degrees on 0w20, no thank you. I haven't even mounted my 38/13.5R17 MT's yet.

Don't forget to sign up for their Prefered Customer program, 12 quarts for 145 bucks. Sign up for their helpful site sponsor here. Dude runs 40 in his Taco and you are hesistating with a Raptor lol.
If you want to go nuts then Redline 0w40. But that's totally overkill and unnecessary. Amsoil is less expensive and has the creds to run long and clean.

It might run a tad hotter with the 0W-40.
 
I have a little over 400 miles since I switched to M1 0w40. I see very little difference in the truck. However, the oil pressure gauge looks a tad higher, but it’s hard to tell since it’s the factory band gauge. The oil temperature seems slightly lower. We’ve had several 100+ degree days and the oil temp has been consistently 2/3 of a hash mark lower than it was with 5w30. Mpg is exactly the same at 17.4.
Overall, I’m glad I switched. The 0w gets oil to the turbos a bit quicker and the 40 gives a little better protection when hot. Hope it doesn’t blow up. Haha
 
Ohhhh boy not another one with the 0F rating being faster or protects better.
But this is what LiquiMoly says,
