As near as I can tell, there's not much interest in 10W30 HDEO here at BITOG, and certainly not in the low phosphorus offerings of some of the CK-4 oils. Still, here is a sample of 10W30 that happens to be dual rated (CK-4/SN) and therefore the phosphorus is limited at a maximum of 800 PPM. I am contracted to a carrier that offers me extraordinary value in their oil change services and their shop is full of all things Delo and Donaldson (filters).
With CJ-4 oils (meeting Detroit's 93K218 spec), the oil change interval was 50k miles or 1280 hours for an OTR truck like mine. Now with CK-4 (Detroit 93K222), I can go 55k miles (no hour limit listed). With limited idle time, I could go 65k miles.
I'm an OTR guy going all over the U.S. but I pretty much haul for a small group of customers that require me to haul heavy. No overweight permits, but have a lightweight truck and trailer to haul near 50k lbs and still be under the 80k lb gross weight limit. This oci saw about 2300 miles empty, with the rest of the miles being driven at or near 80k lbs.
2016 Freightliner Cascadia
Detroit Diesel DD13
450 HP @ 1450-1625 rpm and 1650 lb/ft torque @ 975-1500 rpm
31 psi max boost at 1500-1600 rpm, down to 22 psi at 975 rpm
Turbo is not variable geometry and not water cooled (imagine that).
Delo 400 XLE 10W30
Donaldson oil, fuel and air filters
This oci:
55007 miles
1851 hours (948 hrs driving / 903 hrs idling)
Engine 182465 miles
7295 gallons of fuel burned 7.5403 mpg for the oci
No oil added. At time of drain, oil was nearly touching the full line so perhaps down a pint, basically still full. The shop says they put in 10 gallons (40 qts) and I found Detroit literature saying that approximately 6 quarts are left behind when the oil is drained.
Idling (when parked) is bumped up to 900 rpm. The truck has Detroit's Optimized Idle which starts/stops the engine to maintain cabin temp/battery charge/oil temp as needed.

The 20k miles missing between the second and third reports are because of a
short oci late 2016. I had the overhead adjusted and changed the oil at the same
time but didn't sample it.
Lab is ALS and I changed the <1 to plain ol' zeroes (for the elements).
Everything is taking forever to get rinsed out. Copper, aluminum and potassium, and even moly from early oci's are still hanging in there due to so much oil being left in the engine at each drain.
