Can't you go back to the station, take the attendant, stick the nozzle down his throat and show him that 87 tastes different than 94?. Thats why I always say to them 3/4 times, super right?, and I make sure they repeat it back to me before I give them my card.

The compression ratio of your engine determines the octane rating of the gas you must use in the car.
I have run 87 octane in my ZO6 many times with no Pinging. Obviously if your running it hard then you need at minimum 89-92octane.

i once nearly ran outta gas on a long road trip and the only option at the only station around was 87 (or whatever the lowest grade fuel is here in california). knowing that the next town was about 100 miles away, i filled up with about 1/4 tank and just went on my merry way. no problems. this was just a looooong straight & flat highway road trip, no sporty driving. that probably helped. no pinging noticed.
once back in civilization, i filled up with premium. no problems.

i lived in nyc for several years. out of habit, whenever i was driving in jersey and stop for gas, i'd fill it up myself. especially the stations right outside of the lincoln tunnel on the jersey side. what is it, a union thing?
the various attendants used to pop veins watching me do this and chase me away. hilarious.

I'm one step closer to becoming a Z06 Corvette owner. I just sold my hotrod '57 Chevy that I've previously posted an image of.
This octane discussion got me thinking about fuel requirements. It's apparent that the 405hp Z06 requires premium fuel.
Does the regular 350hp LS1 motor in the coupes also require premium?
Thanks in advance.

If you run 87 by mistake nothing is going to happen this one time, or even a second time if you stay off WOT (wide open throttle). You just wouldn't want to use low octane on a normal basis.
If the computer senses pinging it will realize this and revert to low octane timing tables to reduce timing advance..this will only result in decreased performance.

I ran it out and flushed with 94 octane. I am still having a vapor lock problem at fill ups. The thought of a quarter panel tear down to change the filler neck does not do it for me. I live with it. Thanks for all the post!

In the late 90's caddys were supposed to use hi test. The largest dealer around was telling owners to use regular and in fact I was told it would run better They claimed the gas in the south was reformulated and to use regular from any southern state, but if I got into the Carolina's to buy hi test. I have tried it couple times in a few of my cars since then and had no pinging.
