Aimsoil recommended on their site which I think they are confidence that it meets oem requirement or they wouldn't recommend it having the risk of liability. Lingenfelter does recomend Aimsoil for their built 427 LT2. Each interpret what this means however they choose.
This Thread is going to confuse everyone that posts "will this affect my Warranty", including the dude who is worried about mounting aftermarket wheels lol...
lol.... this thread, before today, hasn't been used since August.... I don't see anyone asking about wheels here.....
You will when you catch up on the other threads...

Does snow tires void your warranty?
What about road salt on the paint since a SR was not advertised for winter unlike the Eray?
I think I'm safe with my aftermarket valve stem caps ......... 
No, there are encouraged..Does snow tires void your warranty?
All I'm saying is It's not "Dexos" approved. It could quite likely be far superior to Mobil 1.
Edit: Corrected Dexron to Dexos

Could be. I think Dexos is a GM only designation? They also have the FFL-4 DCT for the C8s as well.
Sorry, I meant Dexos. Yes, it's a GM designation.
Found this....

From the internut.....
Yes Dexos is a GM specification . GM recommends 0W-40 dexos2 (or dexosR for newer specs) synthetic motor oil, such as Mobil 1 ESP 0W-40 or Supercar formula, for the Corvette LT2 engine (found in C8 Stingray models). Warranty Requirements . Using the specified dexos-approved 0W-40 oil is mandatory to maintain warranty coverage, as deviations can lead to denied claims on engine-related issues.
GM ties warranty validity to adherence to their fluid specs, including viscosity and certification, to ensure optimal performance in high-revving LT2 applications. Oil Capacity and Filter . The LT2 requires about 7.5-8 quarts of oil, paired with the OEM AC Delco PF64 or equivalent filter.
Stick to factory-fill equivalents like Mobil 1 for track or extreme conditions, as they're engineered for the engine's demands. End of story.
