Does GM recommend to use high test in our vettes? If not used does it nullify our warranty?

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend TOP TIER Detergent Gasolines. See www.toptiergas.com for a list of TOP TIER Detergent Gasolines.
Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane is less than 91, you could damage the engine and
may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service. Use of Seasonal Fuels Use summer and winter fuels in the appropriate season. Driving or starting could be affected if the incorrect fuel is used. Drive the vehicle with the engine running until the fuel is a half tank or less, then refuel with the current seasonal fuel. Prohibited Fuels Gasolines containing oxygenates, such as ethers and ethanol, as well as reformulated gasolines are available in some cities. If these gasolines comply with the previously described specification, then they are acceptable to use. However, E85 and other fuels containing more than 15% ethanol must be used only in FlexFuel vehicles.

Running C7s on only stand-alone premium shell v-power (not flying j) or co-op zero-ethanol premium. In the states pumps that have no ethanol premium signage.
Crossing “T’s” and Dotting “I’s” if/whenever a discussion needs it during warranty. The C7 has surprised me with mileage regardless so it’s not about a net saving of pump $$$. Beats the heck out of me driving my GMC.
Although Shell and V-Power Signage, We found ... “Contains Ethanol” stickers on the pumps in Calgary ... and nobody could explain to us why when we asked inside.Why not Flying J?
A few operators of stand alone shell stations know about the fuel they sell ... even people at a COOP station in the middle of nowhere Alberta knew and could assure me of what they sold. I have to assume Calgary’s flying j somehow may put ethanol in their Shell VPower because there’s a sticker saying so. I wonder why? Also wonder if other shell flying-j’s sport the same ethanol stickers on their pumps.Assuming someone knows more about selling coffee, cigarettes and lottery tickects than they do about which stickers go on which gas pumps....

If the sticker is there I would expect it to be correct. Oddly enough the gasoline we use is not all created equal. Despite the precise processing and quality control it’s somewhat like whiskey. Even our cars are designed to operate in a range and not necessarily an exact. It gets more precise with high end racing fuels that are very exact in octane, additives and quality as these engines and tune setups require a more excact fuel to operate properly and safely.
Yes it is not often anyone working at a gas station knows anything about the fuel they sell anymore. Pretty much up to the car owner to do his homework now. Most cars it makes no difference... but Corvettes and other modern high performance cars... fuel quality and composition definitely matters.
I just find it amazing we can buy a 700hp car that runs on pump fuel today.
Awesome & Thank you ... there's a phone App to load that I can use on the USA tripsA buddy drives a tanker, and delivers to gas stations. He claims zero ethanol in our gas, due to lower gas prices. (when gas is high $$$, ethenol is cheaper).
Here's a good site for individual gas stations, Canada and US:
