Regular or premium
I know that Chevy recommends premium gas in the 6.2L engine. What do all of you out there use? Is using regular a bad idea?

not even and Shiner are both right and it’s dependent on many factors.
The beauty of modern higher performance efi engines is that most all will compensate for lower octane than recommended. To what degree is dependent on not only the engine specs and tuning but also temperature altitude and load on the engine.
To the OP, it isn’t going to blow up with one tank of low test. Try it out. Pre detonation will be obvious. Lack of performance may or may not be. Fuel mileage if tracked accurately can also be an indicator of how it performs overall with different octane.
The old saying that too much octane does no good is still true. But under load, reduced perf from too high of octane will not damage an engine but too little octane can. Generally over time and exaggerated under heavy load.
