Having said that I would avoid these two brands for now.

Didn't Rotella T-6 reduce the Zinc and Phosphorus levels as well? If so how about the T-4 and T-5?

Rotella did not reduce the Zinc and Phosphorus levels in their T6 5W40 and their T4 and T5 engine oils. The reason is they decided to not make them dual rated for diesel and gas engines which IMO was a good decision.

15W40 that meets factory spec. Fleetguard (Cummins) filters.

[amxpress]

I run Amsoil 5W40 Signature Series oil and a Donaldson Blue or Amsoil oil filter. I’ve used Amsoil for ove 30 years and I do an oil analysis every other change.

DELO 15-40 BLACK CAP/Mopar filter
Just used the last of my LE black cap DELO.
Now forced to use RED cap Ck rated DELO.
190k(mostly towing ) uses NO oil between changes.

Plain ole Rotella and Ac Delco filters. I really put zero thought into it.

Blackstone say exceptional and keep doin' what your doin'

While not a Cummins my oldest truck a 99 Ford 7.3 has run Rotella T-4 15w40 for 255k miles, no engine blow by or smoking.

I run Valvoline premium blue 15-40. for oil i use fleetguard or mopar. for fuel i use Baldwin. I have a 06 as well. 198000 miles.

[srt20]

Valvoline, Rotella, Delo, Mobil, etc, will all serve you well. 5w-40 or 15w-40

Fleetguard, M1, Fram Ultra, etc filters will serve you well also.

[garyp4951]

Rotella T4, and Fleetguard LF16035 StrataPore filter.

Oil is like mouthwash, everyone has their favorite. I just go by the API cert and the manufacturers reccomendation on change intervals...

It doesn't get crazy cold or hot here and since the Cummins will happily go 500~1M miles on Dino, that's what I use. I tried syn for a few changes but saw no difference in mileage or anything else. Since I can't take advantage of it, it's just a waste for me to use syn.
