Mobil 1 - Advanced FS VS Truck/SUV for towing?

[SoCalAngler]

Hello all-

My NEW 2023 GMC Sierra 3500 HD, 6.6L GAS / 6 Speed Trans, Crew Cab, 4X4...

Owner's manual calls for 5W-30 DEXOS 1 - Gen 3. Manual doesn't suggest anything different for towing.

I contacted M1 and they sent me the attached (see link below). When I asked what the differences were between the flavors of Advanced Full Synthetic and Truck/SUV (attached shows specs are the same), they said any additional information, beyond what is in the attached doc, is proprietary.

So are there any differences?

Since I do tow, I wanted to know what the differences are, and if substantial, perhaps that would be a more appropriate choice seeing as the Truck/SUV is also Dexos 1-Gen 3 approved.

I do plan on 3K OCIs, as the truck is not my DD and it's used primarily for towing (TT, boat).

Thanks!

I'd just use 5w30 EP. PUP/Castrol EDGE 5w30 are also very good.

It's just a joke. Auto fill usually puts it as Mobile like in Alabama instead of Mobil .. happens here daily..

Perhaps I should also consider EP....it's just that Truck/SUV claims it is for higher temps when towing

Great truck by the way..
I hate that GM Dexos nonsense though. Causes confusion for one.

Thanks! I was a Ford guy and this is my first modern GMC. So far, I like it! Probably my last truck, so I want to maintain it as such (severe duty maintenance).

Geez...sort of the same here .
My last Ford was a fiasco and I looked at GMC but didn't pull the trigger yet. Most likely my last truck too. I seen one today and it was awesome. Good luck.

I towed all over the Rocky Mountains pulling a 5,000 pound-30 foot travel trailer running 0w/20 in a 5.3 2018 Silverado. The truck didn't blow up.

3,000 OCIs are a waste.

I think either are fine. I’m running the truck and suv in mine because it was available when I bought oil. Id have no hesitation using the advanced synthetic if truck and suv weren’t on the shelf.

Not quite sure where to post this? My '24 GMC 1500 6.2 Denali is coming up for an oil change at the dealer. I presume they will use Dexos 1 Gen 3 but wondering if I should consider another brand of oil that would exceed the Dexos standard? Ideas would be mobil 1, amsoil, Royal Purple, etc. Manual calls for 0-20. My driving is primarily local trips 30 miles and some longer highway distances, no towing. I plan to change between 5-6K miles. Live in Midwest.

Any name brand Dexos 1 Gen 3 will be good to go. You can run boutique oils if it helps you sleep better. I am a fan of 5k intervals regardless of oil in a DI engine.
