Also 5w40 vs 15w40 opinions. I realize this topic has probably been covered many times, but I want the latest and greatest opinions and minds to base my decision off of. Also does anyone know what the Factory Fill might be on this truck? Why is Amsoil not on Fords approved oil list? I tow 8500lbs-9000lbs 5-6 times a year. temperature here is 32-105 degrees. June through September are typically over 90 degrees.

Factory fill is 10W-30. You will, undoubtedly, receive many opinions on this. I run 5W-40 because the justification on Ford's part for severe duty is not much and for the cost difference, for me, it is easier to use 5W-40.

Amsoil never is usually on nobodies list. Its not even on GM's DEXOS list. Just use Rotella T6 5w40 and call it a day. If you want to use 15w40 or 10w30, than you a lot more options.

One of our managers put his on Delvac 1 5w40 on the first change a year ago. Pulls equipment too.
Service manager barked a little but the technician had already told him several folks were unhappy with Fords attempts to push Motorcraft

That's child's play compared to what we put our F550's through.... 20,000 lbs trailer loads every week for hundreds of miles.

From your owners manual the reccomended oil is 5W-40 CJ4 and is the oil recommended for severe service.

The 15W-40 is old school and is no longer recommended by Ford for this engine. Ford recognizes that wear also occurs during starts and a 5 weight is much better than a 15 weight for this.

Heres an option. Dont pay attention to the cost. Its the marked up Canadian cost that they never sell it at.

OP asked about 5w40, so either Rotella or Valvoline Premium Blue are readily available. It's a wash, neither is better than the other.
I don't agree that 15w40 is old school, and it is still specifically in the owners manual and on Fords approved list.
Factory fill is 10w30, and what Ford recommends unless severe service, which basically amounts to towing over 1000 miles, or cold temperatures.
All that being said....
In the temperature range mentioned, and the OP's towing (9k, you won't even know it's back there with this truck) you can run pretty much whatever you want (and call it a day).
My opinion, Valvoline Premium Blue Syn Blend 10w30, and a Donaldson P502503 filter. Boring VOA, excellent UOA, follow the change minder, and drive.

Rotella T6 or Delo 5W40. It should meet the Ford spec. Some of the initial blends of CK-4 did not meet the Ford spec and people stocked up on CJ-4 which did.

Amsoil will be fine but others are just as good.

A bypass filter will be a good addition, I have one on my F250.

Delo is not on Ford's blessed list. And won't be until Ford get's their act together.
Here is the link again. Henry's Nice List
I agree (in theory) that bypass is nice, but the best way to keep oil clean is regular changes. Of course, campground bragging is worth something.

Directly from the 2017 owners manual For severe duty service use SAE 5W-40 API CK-4 And yes, you can run whatever the heck you want.

If anyone is wondering when Ford started recommending 5W-40 for severe service instead of 15W-40 it was 2011, when the 6.7 Powerstroke was introduced. Thats 7 years ago. I wont argue if this is retroactive to prior engines.

I stand by what I said. 15w40 is in the recommended list, and yes you pretty much can run what ever you want.
5w40 may be great for temperature extremes, but the wider spread can shear more readily than a 10w30.
Severe duty is defined as towing over 1000 miles, or extreme hot or cold operation. The OP isn't freezing his rear off, or melting in desert heat. A 10w30 would be just fine. But again, you can run almost anything as long as it has 1000PPM of P and Z, the
WSS-M2C171-E spec.

Comments on the wider spread shearing more readily are from the old days and Ford knows that.
