I've got a 23 and 24 HO and both came from the factory with not enough oil in them. I trusted the dealer to check the first one and knew better on the second one. Both were three quarts low.
Oil for new 6.7 High Output

THere's a post floating around here somewhere maybe @BroncOh made it? Might be someone else, that talks about there being a revised dipstick and SSM/TSB; don't quote me but I think the findings was that ALL 6.7 oil pans could accommodate the 15q of the newer truck spec without foaming and churning butter with the crank and that essentially they are all low on oil but have had no history of issues running at 12-13q.

Triax does list 25K for pickup OCI's. You may be able to get that, but I would never run that much. I still change mine at 5,000 for ease of remembering; if the 4th digit is a 0 or 5, change it. Same for fuel filters, when the 4th digit hits a 0, change them. Those that I have spoken with have run 7,500 and 10,000 with good oil analysis results. For me, it comes down to the filter. I just don't trust the filter past about 7,500 miles.

@JTredway : I know there was a HUGE group hug on another forum where they "measured their dipsticks" is some sort of weird seemingly masculine way to resolve the "disparity".
As luck would have it the 6.7L oil pans across the board are all the same......so the appearance of a "longer dipstick/shorter dipstick" really has no merit to any significant issue or probability thereof.
To which those of us who can pour in motor oil based upon a specific measurement of liquid volume aren't concerned to one's own "dipstick" length.
Since understanding all this I'm now in the camp of "another 1-2 quarts isn't going to hurt"...I'll be adding 2 qts on the next oil change to see if there's any effects. Speaking of...upon a longer HWY run I did think to add 1qt to see what happens...well...no issues.
Even worse is IF we were to add any aftermarket pan to the equation (rated between 1-3 quarts) we "could" add almost an WHOLE GALLON of additional oil. That would be for say 2022MY trucks stated to be spec'd at 13 qts, an additional 2 more to the OE pan, and IF using a pan at 3 qts "over stock"....easily another gallon of motor oil if my basic high school math is right.

I did my first oil change at 1000 miles and the second at 6000. I used Valvoline Premium Blue both times 5/40 with Motorcraft filters. I did my first fuel filter change at 6000. For fuel going forward I will do them every other oil change. Planning future oil changes at 5000 mile intervals. Overkill for sure, but piece of mind for me.
I missed this, sorry. For filters I would stick with FoMoCo while under warranty. They could deny you for a filter if they want to be a PITA and claim external failure some how.
The factory filter (any spin on filter in the OEM location) does not filter fine enough to remove soot, it physically can't without becoming a restriction and not allowing full flow. Soot loading is what will be your problem with extended oil changes beyond 12-15k miles. Soot is very abrasive and in low PPM levels not terrible but eventually will become a fine liquid sand paper.
This is where a bypass filter comes into play, various ways they connect but usually they Tee off the oil pressure sensor or sandwich plate. What it does is siphon off a very small amount of oil and runs it through like a one micron filter (sizes may vary but smaller than like the OEM 10-12micron rating) and then returns it to the sump. Like it filters such a small amount to the side it might take 5hours of driving to consider the whole oil system ran through it (I don't remember what it is but its off microscrubbing the oil doing it's own thing) to the point it can remove soot and keep oil it's liquid honey look. At that point as long as TAN, TBN, Soot levels are all within spec you absolutely probably could get 15-20k plus on an oil change. Just a matter of your ROI and what you decide is worth it.
In theory your wear metals will plummet too bc of increased filtration so you might lose some early leading indicators of pending failure.
Run OEM Filters. Run oil samples to determine your comfort level with your oil of choice combined with OEM filter combined with time on oil. Fuel should be drained at the water valve yearly and roughly every 10-15k miles according to spec. I have a DCR so less concerned better for fuel filters while still a priority I'm less stressed.
I have enough oil samples with Triax and FoMoCo filters that I don't have an issue trusting the factory oil minder.

yes I just put in 15 qt and go on. My 23 has 117K on it now and doesn't seem to use much between changes every 7500 miles.@JTredway : I know there was a HUGE group hug on another forum where they "measured their dipsticks" is some sort of weird seemingly masculine way to resolve the "disparity".

Ok, thanks for the explanation, I follow you now.
I never intended to stretch the interval between oil changes, I was just very surprised by what I read on their website. I have every intention of letting the truck tell me when it's time to change the oil.
Also, I usually stick to Motorcraft filters, so that will continue to be my plan with this truck.
I appreciate your great explanations, and the heads up on Triax oil, I absolutely plan to use it. I will probably make the switch after the first 1,000, as that's always been my approach on new engines, for peace of mind.

I was a detractor of Motorcraft oil filters on the 7.3L because they all seeped a small amount of oil. I am back on the Motorcraft bus for the 6.7L because a) they specifically updated the filter design to FL2124S and b) the cost of other brands is at least double! If these seep oil too I'm not sure it's enough for me to accept another $25/OCI.

Thank you to all who have responded - and to those who have yet to respond. Quite the education.
I had not heard of Triax Lubricants before but will be looking into them ASAP. (I tend to be OCD too.)
Although my original question was more about why both Ford and O'Rielly showed the Motorcraft 5W-40 Synthetic as not "fitting" the 2025 F-250 High Output Diesel, given the experiences shared here, I'm good with accepting the idea that the websites just haven't been updated yet - and that all of the oils mentioned so far are more than adequate for a new 6.7 High Output Diesel engine.

Whatever Ford puts in it. Fourth Super Duty and haven't had a single issue with any of my trucks.
Same for me. Sticking to 5k intervals it is good enough for regular duty.
You might get crucified if you do

#1 : Some systems will return the by-pass flow to the normal oil flow path.
#2 : I'd agree with the "time of flow" through the by-pass to filter the whole oil capacity.
I run Schaeffer 5-40 in mine
I run the EXACT SCHAEFFER 5W40W in my 6.7. Had never heard of it prior to my diesel shop, TRUCK SOURCE DIESEL, San Antonio, Tx recommendation. TSD has been in business nearly 2 decades and is reveared as one of the top tier diesel shops in the nation. I trust them 100%
Definitely good oil but $47.53 a gallon ouch
I buy mine at $41.00 gallon at TSD.
I use valvoline premium blue 5/40. Napa has it on sale every now and then.
Rotella always makes my diesels smell like they’re burning oil

Well diesel fuel technically is oil so yeah you are burnin oil
