I have, hard to tell the difference with these engines. I’ve got 36k on my LZO, and have used the ESP on two oil changes. But again it seems more expensive the AC Delco and I’m not sure what you are gaining
ACDelco DexosD. 0w20 is practically water, but GM says to use it in the 3.0L Duramax and until the warranty is up, there's no reason to change varieties.
ACDelco for the first change, and Amsoil since. I can’t tell any difference. Always an OEM PF66 filter
Used ACDelco for the first 4 oil changes and then switched to Mobil 1 ESP X2 when RockAuto didn’t have the ACDelco in stock. Haven’t seen a difference.
