No relation to the point of this thread, just in relation to 69GTX's post.

Sounds like dexos1, but it's strange since dexos1 does not allow any Xw-40 grades currently.
PS: you can upload pictures directly to BITOG nowadays.

As a mod I should have known that this ability to add images was on here by the way, my bad!
Thanks, Patman.
Well, that's intriguing, to say the least.
The book symbol probably means RTFM. Do you have access to the owner manual to see if there is any additional detail there regarding oil?
Given that dexos2 is meant for diesels, then it probably wouldn't be dexos2.
Given that dexos1 does not allow Xw-40 grades, then it probably wouldn't be dexos1.
So what then? Is GM about to launch a third/brand new dexos category for high performance vehicles where this M1 0w-40 would fit?

Either a third category or notate dexos1 accordingly (like Mercedes do for the allowable AMG grades).

Right, such as "Meets the performance requirements of dexos1," but not the fuel economy requirements, or some other such weasel lingo.

Not yet, they only have up until the 2018 owner's manual online (which I've already read!)
As soon as I find out more info about this oil I'll pass it along on here for sure.

Ohh, this is interesting. I'm using the M1 FS0w-40 in my supercharged truck now even though it calls for 0w-20 dexos1. I did notice a fuel economy drop of 1-2 mpg, but I haven't changed the oil yet so I have no analysis to compare. I'm curious how this new GM spec 0w-40 will do...
