look at the big picture.GM sells cars in volumes whether it be
a Corvette or a Cobalt.As many a cars as GM sells world-wide
don't you think that if a Corvette could be run on a regular
basis with 87octane gas they would want to pass on the
savings to us,and inform us as well?
They're looking for buyers in an extremely competitive
market,as well as repeat buyers.Why put premium
recommended on the fuel door,window sticker,and owner's
manual of Corvettes if they didn't have to?
They're in it for the $$$,they have enough headaches dealing with
C.A.F.E. regulations.
It's just common-sense,new poster or not.

First of all Gordon is not an engineer , he is an assembly line mechanic, and is very knowledgeable with the C4 platform...
with the L98 engine and the LT1 both completely different animals.. BTW Gordon's specially was trouble shooting wiring problems at the end of the assembly line...
Now that is Enough said.

Gordon is excellent with the C4 NOT our C5's.... the L98 is a wonderful old workhorse but kinda like comparing a Carter AFB to an injector

interesting concept: detuning the vette to get less power. on another note, I've found that NOT using top tier gas lowers my performance also. -bmb

I live out in the sticks and the local gas stations only sell regular or deisel. I was using Regular for a couple of tanks (91) and filled up with Super (94). The difference was immediately obvious to me. I don't suffer from pinging but the ignition has to be compensating. I can't believe guys can use 87 and see no difference
the best I can get is 91

OH 2 Fun says:The lower the resistance, the more chance you have that the "combustion" will occur BEFORE the piston reaches top dead center.
When this happens, the combustion occurs while the piston is still travelling UPWARD.

Wouldn't it be great if after clicking on the dead horse icon someone leaves in response to a serious query that you got linked to the previous threads which discussed the topic? That would be SO much more effective. Moderators, will you look into this please? I can think of no single act to turn away members newly interested in the C5 than that damned, overused dead horse.

Think of it this way. Premium is only 20 to 25 cents more a gallon. That's only about $5.00 on a complete fill up!
That's like driving 10 miles in your SUV or Pickup to save 3 cents on regular! Just what the he!! do you gain, nada!!

choices
Yeah, I thought about that as I wrote my response. But I also think that some people would rather ask their specific question rather than to search and try to dig for an answer.
Plus I've found that Corvette lovers love to talk about their 'Vettes. They're happy to help new members enjoy their vehicles to the fullest, even if a question has been asked just a few weeks or so before.
Some may see the multitude of fresh faces asking the same ol' questions on the forum as the beauty of modern technology, and others may see them as clutter. The great thing is that we all can choose what we click on and choose what we want to respond to.

Does everyone really understand what the "Octane rating" means????!!
It's all about when the fuel/oxygen mix ignites under compression.
The higher the octane, the longer the fuel resists combustion.
The lower the resistance, the more chance you have that the "combustion" will occur BEFORE the piston reaches top dead center.
When this happens, the combustion occurs while the piston is still travelling UPWARD. Total resistance and pounding. Damage.
pre-detonation
With a higher resistance to combustion (high octane), the firing of the fuel/oxygen mixture happens later in the compression stroke so the piston is more likely to be already on the DOWNstroke. Hello...more power....no knocking......less damage.
Nuff said??
I hope so,....I'm exhausted.....

Excuse my ignorance, but I believe that this is the point where this thread stops condescending and adds its value in knowledge. Am I to understand that "detonation" is the equivalent to "knocking?" What is the precise time in the pistons stroke for combustion? When you speak of "knocking/pinging", is this because there are TWO separate combustion incidents? Are there more?
If so, it would make total logical sense that 'detonation' could in fact be prevented by the use of fuel with a HIGHER octane rating, no?
I believe that there has been a misunderstanding as far as fuel efficiency and financial efficiency are concerned. There lies some irony in the fact that one would spend the money it takes to buy a Corvette only to turn around and decide that modesty/frugality are now the objective. Trying not to be judgemental, but would one also take their car to the car wash? Run "used" tires? Throw trash in the passenger seat?
I am being facetious.
Seriously though, someone please explain how this whole "combustion/pre-egnition-TDC" thing works so I can understand.
Truly seeking knowledge...<----------

same to ya.
And I agree with you to a point. This very question was posted about 3 days ago, if I remember correctly. I like sharing the knowledge that I have gained, thru Vette ownership, with new members also. I think that out of 4700+ posts this was maybe the second "dead horse" post that I have made. Here's to ya . Have a great weekend.
