BTW, OP, on another note. It would be advisable to use only top-tier gas in your Vette. The reason you want to follow the manufacturer's guidance with regard to octane level is the fact that you have a high-compression engine. using 91 or higher top-tier gas will assist your engine with piston crown cooling and carbon build-up. You should also treat your tank with Techron octane booster if you have been using 87 octane gas in your car. Here is a link to a list of top-tier stations:

It is more expensive to buy top-tier gas, however, in the grand scheme of things, you will save yourself a ton of potential engine issues down the road

Some of us not only recently bought our C5's but bought them USED and they didnt come with your 'owners manual'
It's 'senior' comments like yours that drive the new members away from asking questions. Honestly, if your comments are only to be a smart a**, no need to make them!

My view is that you should avoid making the car adjust the timing. By definition the knoock sensor is compensating for the pre ignition thats already occured. Its after the event. Any pre ignition is bad as the damage, however small, has already occurred.
We all spend a lot of $ on our cars. The extra .10c a gallon is probably a sound investment if you look at strip down costs.
BTW you can download an owners manual here:

not only that, but many people have been fooled into believing that technical people write the owners/service manuals.
While it is true (that they are a part of it) ... lawyers also have input.
Many times - the search for the truth lies outside the owners/service manuals.

My original post was TOTALLY wrong!!!In fact...You shouldn't even need the owner's manual to know that your 'Vette needs HIGH octane fuel!!!
I'm starting to realize that not all 'Vette owners are gearheads (I'm certainly not).
Some are

okay so maybe i'm wrong and i use premium anyway so don't knock me but i heard something from like dateline or whatever that the gov is in partnership with the gas companies and they are the ones saying premium fuels only cause they get kickbacks on it? someone got sued and so new cars don't say that anymore. My newest vehicle is 04 so I haven't verified that anywhere but it all comes out of the same truck and same tanks so we are probably all paying an extra $2-4 every fill up so mr Pres can drink his tea.
