Any CJ oil that’s not also CK rated is okay as long as it meets viscosity spec. CK oils need to meet the Ford lubrication spec. You can see Ford’s position statement and a list of approved brands in the link below. I don’t think Delo or Valvoline are listed at this time.
Ford Diesel Oil
Valvoline is on the list, but delo and delvac are not which is why I didn't recommend them.
The bottom line is to use an oil that meets Ford specs.
I use Delo 400 SDE that goes on sale for $28 for three 1 gallon jugs. It meets Cummin's specs but not Ford's. Delo 400 is API CK-4/SN which they claim in their marketing that it provides up to 50% better wear protection than API CJ-4. Ford recommends CJ-4 and not CK-4/SN for some reason, so go figure.
Looks like your choices mostly come down to one of the Rotella oils or Motorcraft.
