Same can be said about Valvoline Premium Blue oil that advertises their oil is "Endorsed and Approved by Cummins" on every bottle and people think they have to run it because it's recommended by Cummins.
Egggzactly!
FWIW, the only oil I won't or don't run is Rosmella T4. Or haven't in a while anyways.
Aside from the odiferous emissions, and I'll qualify with I don't understand why or how, my old 5.9 would drink T4. Couple qts between oil changes, vs never adding oil between changes any other time, except when I took off once for long trip with about 10k miles on the oil and it was down a quart.
I am a REBEL as I run AMZ/OIL. :B
