5-30 for sure + better yet a 10-30 in warmer temps. the lighter base oils burn off faster hence the better noacks seen with 10 vs 5 W's. my girlfriends oil thirsty DI 2.5L 13 malibu with 60 thou gets a 5-40 + drinks a LOT less, use what works + protects best unless you trade often + let your problems to others.

I seriously doubt it...

Of course there is going to be more wear protection. The debate is going to be will it matter.


Im not trying to start a so called shark meat thread? I am planning on keeping the truck until it falls apart and i am forced to buy a new one. So saying a 5w20 wont matter at 250k miles i understand. But will using a 10w30 keep wear rate lower at 500k? I know its not a logical queation but im looking for an answer for decades down the road and a million miles. My truck is at 40k miles almost and i just want to do whats best for optimum longevity with proper maintenance and care.
 
I'm using a 30 grade in my 2018. I plan on keeping it a long time. And it makes it easier as I can use it on my small equipment at home and my wife's ecoboost 2.7. The 2018 seems to have a little bit of fuel dilution which gets a 5w-20 down to 6-7 cst in pretty short order. I'm using the 30 grade to combat that some and give me some extra protection for when I'm at the track or towing in the heat. I'm using a conventional now though as I don't plan on doing extended oil changes. Just follow the iolm and change it when it tells me. I would have no problems going up to a 40-50 grade but I want to stay somewhat thin because of my climate.

Yes and that's why Ford and Subaru both double clutched and went back to 5w-30 on certain cars.

Be honest. Are you realistically ever going to reach 500k miles? If you do, you are a rare breed. If not, what are you accomplishing? I've had several hard use vehicles go close to 300k miles on Motorcraft synblend 5W-20. 6.2L F-250's that tow/haul near their max six days a week.

You have 40k on a 5 year old truck. I don't think you're going to have to worry about 250-500k. I have 101k on my 2013 and I seriously doubt I'll ever see 250k.

Then don't use 5W-30! That's [censored] Cafe oil! Use 10W-40...

With a primary goal to keep until the wheels fall off, I'd want to be sure of the best protection, least wear oil for the application. The engine will run fine on anything from a 20 to a 50. Sounds like it's time to perform your own testing rather than relying on opinion.

So I suggest a run with each of 5w-20, 5w-30, 0- and 5w-40, and 5w-50. Make sure each run has a new filter and similar conditions as the other runs. At the end you will have solid data on wear and can go with whichever oil does the best for your Coyote.

So with 3 oil changes to get a wear pattern for your engine at 10k intervals that would be 150k miles of data to go with your 40k. You will be at 200k with proper data to get you to 500k

Plenty of ways to do it, yours is one. It's up to OP to decide what testing will be valid for him.

Or just run a slightly thicker oil and not worry about it. If Ford thought 5w-20 was the last word they wouldn't have switched back to 5w-30 in some engines or speced 5w-30 out of the gate with certain engines. Trust the engineers.

Bingo. It makes you wonder why doesn't it?

Devil's advocate- Would there be a downside to the OP going to 5-30? I seriously doubt he'll notice an MPG change... And it's wash cost wise.

I dont mind loosing mpg to gain protection if its there. I will put my current fill through its paces and fill with 5w30 and see what Blackstone says.
 
Ford was one of the first to use a 20wt oil. And millions of combined trouble free miles have been put on thousands of Ford engines on it since! People way overthink this subject. That engine will never know the difference between the 20 and 30.

This^^^^^^^^^^^^^^^^^^^^^^

How many threads have we seen with this subject? Just change the make of the vehicle and the motor.

Running 5W-30 all the time is what I'd do because it's not going to hurt to have a bit more protecton headroom.


Nobody's motor is going to self destruct or wear prematurely because of 5W/20-Oil.

Right ... instead of getting 20 mpg, you will get 19.8 mpg, and instead of the engine lasting 275 000 miles, it will last 300 000 miles ... and you, in all likelihood, won't own the truck. EVERYONE says they are going to keep their vehicle forever ... almost none do.

As I mentioned, it depends on how it's driven that will effect on how close you'll get to an unacceptable minimum oil film thickness. I never said it will "self distruct", but if the MOFT is not good enough under certain use conditions then it certainly could cause more engine wear over the long run. That's been discussed many times here with all kinds engineering test data shown to back it up, as well as various manufacturer oil recommendations in their owner's manuals.

If someone wants to ensure adequate MOFT then 30 will give more engine protection headroom over 20, just like I originally said.
