Most likely nothing. My Volt calls for premium gas and I just use regular, never had an issue. But that engine is mostly just a big generator producing electricity for the electric motor. I’ll cough up the extra money for premium for the C8. My SLK32 AMG called for premium too, so that’s what I used. I think premium is the right way to go in a performance vehicle. Now if I was somewhere and needed gas and no premium was available for some reason, I wouldn’t hesitate to put regular in it, it won’t hurt it.
There are some guys here that wouldn’t even consider putting anything other than certified “Top Tier” premium in their Corvette. That works for them.

When I owned my 2014 Stingray and was living in CA, 91 Octane Premium Gasoline cost $4.50 a Gallon or more.
We recently moved to the South, and 93 Octane is the norm and it costs about $2.50 a Gallon.
We even have Ethanol free Gasoline available here for a little more per Gallon.
No Regular Gasoline goes into the 2020 C-8 I am buying, unless we end up in a Road Warrior Situation.

has nothing to do with "who wrote the tune" and everything to do with what fuel the tune was written and tested on. The vast majority of GM performance vehicles are OEM tuned on 93 octane. GM used to put a notice in the owners manual of reduced performance if you use anything less than 93 or Premium. In the last couple of years GM has been putting an additional disclaimer that if you dont use Premium unleaded as close to 93 octane as possible that engine damage can occur and that the damages may not be covered under warranty.
If you want to run 87 octane then buy a Toyota Corolla, dont be a cheap *** and buy a performance car and then try and save $5 per tank by running the cheapest gas possible. The only way i would run 87 is if it was an dire emergency or a last resort and then I would keep the engine out of WOT and any lugging at all.

Side note, to anyone who thinks its "dumb" to run regular when you're on the street, you're blowing money for nothing. As long as the ECU can compensate and you aren't running boost, you're fine. 30 HP is roughly what you're getting out of premium over regular.
