North America: 5w30 Dexos 1
UK: 5w30 Dexos 2

The latter implies a Euro spec'd oil. Same engine, same requirements.

Wouldn't this be sufficient to protect my warranty should I choose to use a Dexos 2 oil? How could GM possibly deny a warranty for using an oil that is explicitly recommended in their UK user manual?

Seems like you should be asking GM representatives these questions instead of strangers on the internet because theirs is the only opinion that counts.

LOL, GM representatives don't know the difference between my 2.0T or their 2.5 non-turbo engines. They put 0w20 in my engine.... TWICE!

The 'trust' the manufacturer approach does not give me confidence.

That's what I'm thinking.

I do have PP Euro 0w40 in my stash too.

Yes but they’re still the ones to decide what meets their warranty requirement and not strangers on the internet.

Dexos 2 oils have a HTHS of 3.5 I think while Dexos 1 oils are thinner.
We can debate about our poor gas quality here in North America, too.
I think what it amounts to is a lot of auto makers in the USA sell carbon credits because each 1/10 of one MPG earns them money
by selling it to oil refineries.. .

True, but I'm not looking for their permission. Their manual is clear. Think of it from a legal perspective. What argument could they counter when the exact same car, same engine, same specs, requires Dexos 2?

I think your mind is already made up. Run the d2 oil.


Cannot see signatures any longer so it doesn’t matter.

Another consideration is that I will be leveraging the free oil changes from the dealer for the first 4 years. I just won't be running their oil/filter for very long. So from a paper work perspective the warranty will be happy.

That being said, with the recent post about Dexos 2 having LSPI tests, is there any technical reason I should not use this spec oil?

No one but GM’s legal people can answer that, which is why I said their opinion is the only one that counts. Contact a regional manager or someone in their legal department and ask them for a clarification. You can get 10 pages of internet responses agreeing with you but if none of those are from someone at GM with the authority to honor or deny their warranty what good are they?

The d1G2 oil will serve you just fine for normal driving. If you have a vehicle that was going to tow or drove mountain passes etc then a stouter oil would give you peace of mind. In the end, peace of mind is important.

Europe can handle the lower TBN Dexos 2 (normally diesel) oil because of Europe's low sulfur gasoline-we have higher sulfur gasoline here in the US-wouldn't that be a good reason to stick with Dexos 1 Gen. 2 oil? Otherwise UOA is going to have to determine OCI instead of OLM?

I guess the only thing to worry about would be checking the starting TBN of the d2 you use and making a judgement about what OCI to follow. I don't think that all d2 oils are super low SAPS like, say, M1 5W30 ESP, but you'd want to know exactly what you are dealing with. BITOGer edyvw shared a story about MB dealers in the US blindly using that M1 in all the vehicles they serviced and causing big problems for some of their customers with gas engines.
I believe that Pennzoil mentioned here that at least some people can find at WM is more like a 0.8% SAPS oil rather than 0.6% like M1 5W30 ESP, but I'd have to do some poking around to be sure of that.

OCI's will be relatively short. I'll run the dealer oil for 2k miles, then swap it out and run the XG and oil of choice until the OLM hits 20% (the level the dealer recommends to come in). That should be no more than 5k miles.

Alternatively, I run both oils out to approximately equivalent intervals (~3.5k miles each) and swap out the dealer installed PF64 with the XG the moment I get home from the free dealer oil change.
