Just be aware that it doesn't meet the GM Dexos warranty requirements, so you are giving up the last 3 years of power train warranty.Once the warrantied Mobil 1 oil changes are over, I will use Schaffer 9003D Supreme 9000 5W-30 with a Royal purple filter. Costs roughly what Mobile 1 costs at Walmart. My oil supplier is an Amsoil and Schaffer distributor and he says the Schaeffer oil is better Amsoil's and uses it in his fleet.
According to their website:Just be aware that it doesn't meet the GM Dexos warranty requirements, so you are giving up the last 3 years of power train warranty.
While that may be like Amsoil and be a statement they meet the requirements but haven't licensed with GM to actually use the logo would need to be confirmed.9003D Supreme 9000™ 5W-30

I just looked on Zymurgy's posted list and didn't see anything from Schaeffer.According to their website:
While that may be like Amsoil and be a statement they meet the requirements but haven't licensed with GM to actually use the logo would need to be confirmed.
Regardless, I'm 99% sure that using Schaeffer oil will not cause you any warranty issues.
This is what I run in my Boosted Camaro, no issues and holds up great. I track my Camaro and being that it is boosted I know it is hard on the oil. I will switch to this once my oil gets changed. It is factory Fill for Ferrari by the way.I've been reading about Pennzoil Ultra Platinum Synthetic Motor Oil. The claim is that this oil is derived from natural gas and is 99.5% pure and ultra slick. I am by no stretch of the imagination a mechanic so I need input from some of you guys who are. Is anyone using this product and is it something I should consider? (My car should arrive at the dealership next week.)
So, even if the list is out-of-date (no reason to believe it is), you can identify if an oil is certified by looking at the labeling.dexos® licensed products are easy to identify. Simply look for the dexos® icon on the front label and the 11 digit alphanumeric dexos® license number on the back label. As long as an oil package displays these two markings, the engine oil is an authentic, licensed dexos® product and is recommended for use in GM vehicles.
About the Licensing Program
The dexos® licensing program is administered by the Center for Quality Assurance (CQA). The licensing program is a comprehensive approach to monitor adherence to GM’s quality standards through each step in the product life cycle from licensing to production to commercialization. Oil manufacturers and marketers involved in the production and sale of dexos®-approved oils must be licensed. Licensed products are registered, published, and routinely sampled to ensure consistent quality.
How to Become a Licensee
Prospective licensees may choose to pursue a dexos® license as a Blender or a Rebrander.
Licensed Blenders manufacture engine oil meeting the dexos® specification using previously approved additives and formulations obtained from additive suppliers. Currently there are four additive suppliers with approved dexos® formulations: Afton Chemical, Chevron Oronite, Infineum and Lubrizol. Contact an additive company representative for selecting the best formulation for you.
Licensed Rebranders purchase fully-formulated dexos® oil from a licensed Blender and repackage the oil under their own brand name(s).
All prospective licensees must submit completed licensing documentation and a sample of the candidate oil to CQA for qualification testing. Although the dexos® licensing process is comprehensive and thorough, CQA works closely with each applicant to make the licensing process a simple step in providing an officially-approved dexos® oil to the marketplace.
