Yes, it meets Dexos standards, Valvoline 0W40, European, is a "full synthetic", see the FAQ excerpt below from the Valvoline site and link to the same.

Does the same apply to me, all though I used Mobil 1

Does it meet DEXOS R standards? Did they pay GM the extortion fees to get the Dexos R license? The answer to the second question is a definite no. Considering if you look on gmdexos.com, it doesnt mention it. Granted it mentions things other than Supercar on that site but if you read the bottle on the others, they dont mention GM or Dexos at all.

At the end of the day man run what you feel comfortable with and what will cover your warranty.

You're 100% fine. Dexos doesn't mean shit and if it was a miracle oil, we'd be talking about fishing rods not throwing rods!
 
Not gonna lie, the only reason I run it is so these fuckers dont say it was the oil that caused the issue and then deny me warranty. I wouldn't bet on a lot of differences between most oils of the same ratings. Ive seen a dealership here deny a transmission claim due to larger tires. They look for anything these days to deny.
 
Thank you for the info, just trying to clear the air!

I will run it 5k observe and report anything to you guys
I have an hour drive from my shop to home and everything seemed fine

Really don't want to be the winner of the whose engine grenades first poll

Did you notice any increase in oil pressure?

Nobody's even voting in that poll, you gotta lobby for the other guys or it's bad karma.
 
Oil pressure was at 40 psi
So about the same as before then?

I was checking the codes on my wife's rig and I thought her oil pressure was a tad higher at the same rpms. Couldn't get my OBD app to show oil pressure numerically. Might need to loads some PIDs to pull that data.
