I gotta confess, the low octane vote was mine. My dad swears up and down that its the same stuff and that I should save my money. Hes really really passionate about it.

Re: What grade gas do you use? (1bad85)
I'll swear up and down that it's not the same :D . If i have 91 octane in my tank, i get spark retard .. if i have 93 octane in there, i don't get any (when it's cool out). When it's hot out, i get it even with 93... Your car can tell when you're not using it, and hopefully it will pull timing (aka POWER) from your engine to compensate for the lower octane gas.
I hook my laptop up to my car all the time to watch what's going on ... i usually go to the same gas station for gas, but if I change, I'll hook the laptop up to look at the readings to be sure that i'm getting the high octane i'm paying for.. otherwise i won't go back.
As long as your not hearing pinging, then it's techincally ok for you to use lower octane, but i wouldn't ever put anything lower than premium in these cars. Under heavy load it's easy to get some pinging going on with lower octane.

I can only find 91($1.80gal) anymore out here in CA, so that's what I use. Except at a gas station near Laguna Seca I found Monday. It still had 92($1.99 gal)

Re: What grade gas do you use? (1bad85)
my car runs like a sick dog on 87, i get a little knock on 89 if its hot, so i normally run 92. My ads chip is a little agressive with the timing.

91-93 octane in the vette. For whoever said the gas was the same, we had an old 305 caprice that would diesel until you shut it off in drive on anything less than about 91 octane...would shut right off with premium in the tank

Re: What grade gas do you use? (MrJay)
All I can find in Kansas City is 91 octane. I'd run 93 if I could find it.
Does anyone in KC know where I can get good gas?????

Re: What grade gas do you use? (chilihed'95coupe)
I'd like to chime in with a couple of things here.
First, for MOST cars, octane does NOT matter. So if you have a car in which it does not matter, then use the cheaper gas. Without going into a disertation, higher compression engines (such as the ones in most Corvettes) require higher octane in order to prevent premature detonation (i.e. knock). I would recommend the higher grade octane at your local gas station for Corvettes.
As an interesting side note, in New York, you can get 87, 91, and 93 octane at most gas stations. When I spent some time in Colorado (Denver), I think the levels of octane were like 85, 87, and 89 or 91. I have a feeling that elevation effects the amount of O2 in the air and that you must not need as high of an octane to prevent the knock. Just a guess though. So if your elevation in KS is halfway between sea level and Denver (say 2500 feet), maybe you only need 91 octane :confused: .
I typically use 93. I use 87 when I am daydreaming :bb and don't think about which button I am pushing on the gas pump and 94 :mad (sold at Sunoco) when I want to boost up what's remaining in the tank after using 87.

Re: What grade gas do you use? (Glock'94)
Call me a tight ***, but whatever is cheapest :). The car seems to run fine on Stop&Shops gas(Of course they don't make it) and a few other brands. 92-up octane. Super here is $1.59 at the lowest priced place. I've tried Sunoco 94...and it makes no difference in performance.
