Dexos-Synthetic Equivilent?

Probably bad wording from the service advisor. Cheapest bulk oil they can find that’s still Dexos licensed.
My guess is they are violating the agreement made between GM and dealerships. I bet GM would love to get involved in this.
GM has bigger issues than this.
Not any different than HPL’s no-VII product in that regard. It does have a winter rating but in accordance with the SAE labeling requirements they are not required to list one.
It’s a 30-grade oil and lots of manufacturers recommend those with an appropriate API license.
When I asked what brand of oil they used for the free oil change (first service in the first 12 months 12,000 miles was included in the sticker price) on our 2022 Silverado, the service advisor told me Dexos. I had to explain to him that Dexos was a specification and not a brand. Then he admitted he did not know for sure, but guessed ExxonMobil, and to check with the parts counter. Well, the counter person in the parts department told me straight out that he did not have a clue.
That's the State of the Union these days! You get canned answers from uneducated people that follow protocol.
You get overpriced food and restaurants that serve to you cold!
You get cheaper lighter cars that disintegrate in salt and have electrical problems.
We have to look at the root cause of this.
I personally would insist that they tell me what kind of oil since I am paying for an expensive truck/car and I want it to last past the warranty expiration.
And if they don't know what oil they're putting in then I would seriously change dealerships or do it myself the right way.
That's just my two cents

Yeah, just put a quart in my newest motor - wanted to see the inside of the dealer installed filter - and that takes a quart to do …
Figured straight mono would be fairly compatible …
Maybe offset dilution a hair or two …

Most dealers do not use manufacturer branded oils. They generally buy a bulk oil from a local distributor at a much discounted price, As long as the oil meets the requirements it's good to go. Mobil 1, Pennzoil Ultra or even Walmart's Super Tech synthetic oil would be considered Dexos synthetic equivalent oils.
Two of the oils you mention have dexos licenses and don’t need to be considered “equivalent”.
All three have a dexos rating. I think the term "Dexos equivalent" is being over analyzed. Any oil a manufacturer dealership is pumping will meet the required oil spec.

Pennzoil Ultra does not. Equivalent would denote something close to but not having the license. Mobil1 and Super Tech Synthetics do.
Additionally, if a Chevy dealership is using a Synthetic Blend or Conventional, it isn't using a licensed oil. I have seen some dealership advertisements where conventional oil is the "economy choice".
