Gm Dexos D oil part number has changed (which one do you use in your 3.0 Duramax)?

[Arbetrader]

Hi all, I have an LM2 (2022 my) 3.0 duramax and for the previous oil change I just used the AC Delco 0w-20, with part #19370138 on previous oil changes...

 

For some reason, it appears that our local parts store now has it under a NEW part number 19370139 (only the last digit is different). 

 

Does anyone know if it's the same oil? Anyone else noticed this? One of the Rockauto pages says it's not warranty approved anymore however I can't understand how that could be, as they still sell it for my truck, and it shows GM Genuine OE on it.

 

What are you using (for those who do their own servicing)?

 

Notice the first 2 photos (are of the existing oil that I've ordered and have been using) - PN 19370138

The bottom 2 photos are of the NEW oil - also Dexos D - PN 19370139

 

The DexosD license number on both are exactly the same, but not sure that matters...

 

EDIT: I wonder if it has to do with the labeling? I live in Canada, and it appears the stuff I had used has Spanish on it, while the new PN appears to have french on it (for us in Canada). 

 

For those who use ACDelco OE oil, which PN do you use?

GM does stuff like new part number because something changed on packaging.

 

As long as it's DexosD you're good to go.

Think I mentioned this in another thread,

 

Recently visited the dealer to pick up some oil, and asked the same question about the part number(s).

 

Guy told me that GM now changes the part number every time they obtain it from a different country. So far this year he said they have changed the number at least six times. Same oil.
