Does anyone’s owner’s manual or warranty booklet state that oil grade is a function of the new-car warranty?
That's all fine and dandy however aren't you concerned about voiding your warranty by not using the recommended oil and/or viscosity? This is still a relatively new engine and longevity has not yet been proven. If anything were to go wrong, they will likely ask for proof that proper maintenance was done and with the specified oil. Heck, they probably would deny a claim if even a seal were to fail.
Although not in either of our countries, this article is quite telling and would stand the test of proof probably in any jurisdiction:
I intend to do my own oil changes however will be following GM's recommendations with records and receipts as proof.

Here in the US at least that’s due to the requirements of their CAFE award letter which requires the automaker to strongly word their literature. But there is no warranty requirement in the US.My manual states that a DexosD 0w20 oil should be used (well since Peugeot bought Vauxhall/Opel they call DexosD something else) or if not available then you should use a 0w20 meeting ACEA C5. They give you no option for anything else.
andCaution
Damage caused by improper maintenance
can lead to costly repairs and may not be
covered by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids, and
lubricants are important to keep the
vehicle in good working condition.
Do not have chemical flushes that are not
approved by GM performed on the
vehicle. The use of flushes, solvents,
cleaners, or lubricants that are not
approved by GM could damage the
vehicle, requiring expensive repairs that
are not covered by the vehicle warranty.
So Yeah, it's in there. GM does approve and license other brands but as of this moment, there's only the ACDelco and Mobil Super 3000 XE2 that are licensed.Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Yep....and we have denied warr. coverage when there are looks of wrong/poor oil/lack of changes. Not common, but it does happen.Does anyone’s owner’s manual or warranty booklet state that oil grade is a function of the new-car warranty?
What truck is that? Looks totally different under the hood than mine.Went with Mobil1 0w40 ESP in my 1/2 a Duramax 3.0. The engine is quieter and slightly smoother to drive and I'm pretty sure it's not a placebo.
It's not. Its a Vauxhall Insignia (same car as the Buick Regal) with a 1.5 3 cylinder diesel that is heavily related to the Duramax 3.0.What truck is that? Looks totally different under the hood than mine.
So does it use a cartridge or does it use the spin-on the Duramax 3L uses?It's not. Its a Vauxhall Insignia (same car as the Buick Regal) with a 1.5 3 cylinder diesel that is heavily related to the Duramax 3.0.
That would be a first then as I've never seen anyone on here have a warranty claim denied (much less a warranty claim) for using an oil with a higher HT/HS than listed in the owner's manual. That's really the question here, not that they used Bullseye oil or didn't change it properly.Yep....and we have denied warr. coverage when there are looks of wrong/poor oil/lack of changes.

Yes. In this 2021 owners manual for the Silverado they clearly specify 0w20 with the caution right above it.Does anyone’s owner’s manual or warranty booklet state that oil grade is a function of the new-car warranty?
You are merely trying to divert from your original question that I quoted. That Silverado can tow 12,000 lbs with 0w20 oil.Yes and you do know what that means, right? That you should not use one that has an insufficient HT/HS or without an approval that’s appropriate for the application. That’s what causes damage.
An appropriate equivalent is 504 00 oil being equivalent to the 508 00 oil listed in my VW manual. Sometimes people need to use their brain rather than not understanding what is being written and why. An oil that causes engine failure being the operative concept here.
Yes a little I’ll agree with that. And being able to tow 12,000 lbs with a 20-grade is nice, but not relevant to me I guess. Many owner’s manuals acknowledge that an oil with a higher HT/HS is beneficial when towing or under extreme conditions. I guess I just understand why that is and choose to apply it to my situation.You are merely trying to divert from your original question that I quoted. That Silverado can tow 12,000 lbs with 0w20 oil.
---Should have gone gas......you will thank me later....$$$$$$$ for repairs and maint....trade before the warranty ends and / or buy an extended warranty
I was waiting for one of these to show up here. Never fails. Thanks for your opinion---Should have gone gas......you will thank me later....$$$$$$$ for repairs and maint....trade before the warranty ends and / or buy an extended warranty
God, this argument is reminiscent of 505.01 oil wars on TDIClub.com.
Everyone thought they were an oil chemist and arguably right at that point. The whole CAFE fuel requirement argument is a weak one as it's been proven time & time again that your engine will not grenade on a 20 weight. In fact most of the 30's shear to a 20 anyway by the end of OCI. It is also a well known fact that diesel's in general tend to break-in over an extended period of time. You could see those high iron numbers regardless of oil well into 50k miles.
