Let's see, here premium is $.20 more than regular so if the tank is dry at 18.5 gallons that is a whole $3.70 more, and if you fill up once a week that is $192.40. Just not worth it to use the cheap stuff.

ET and rspreng said it best. Look at how much you save on a fill-up. Certainly not worth the risk. You have a performance ride, give it performance fuel.

You bought a vette,, treat it right. For a few dollars more per fill up it's worth it. With regular you'll get knocking, worse gas milage, dirty spark plugs, fuel injectors can become clogged, lose in performance Is it really worth that few dollars of savings,,

This thread is just not right.
You can probably use dino oil in your Vette too, and save $ on your oil changes, but the engine wasn't designed for it and performance will suffer. With the more than great fuel mileage that these cars get why would you not use the quality of fuel this "performance car" was built for? I guess some buyers of these cars don't plan on keeping them more than a year or two and are possibly the same folks that make the statement in here "It's just a car." I really don't get it.
You can wash your Vette with dish detergent also, but the finish will suffer for it.

i put nothing but 93 octane in mine. My dad in his Z06 puts 89 in on trips where he is just cruising down the freeway and has had no problems but he also runs premium normally. So i would say mid grade would be ok just not all the time. 87 would be ok if that was all you had but only if you were desperate.

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.....

No C5 engineer would ever say that using 87 octane is OK and that using premium is a waste of money, I would venture to say that you were spoofed by a wanna Be....
Here is proof... if it was OK to run regular in a Corvette, there would be millions spent on advertising that very thing... and in the owners manual it specifically says 91 or higher..Not only that but the free press we would get for developing a car that has 350 hp and runs on regular gas.
Here is the problem... you can run 87 octane in the car... but only if nothing else is available.. the car will run.. but not the way it was designed.( this 87 octane OK is only in an emergency situation. engine knock is a very bad thing causing all kinds of problems from cracked wrist pins, to actually burning a whole through the piston.. to crank bearing failure.. of course this all occurs over time.. the difference in cost between 87 and 91 is usually ten cents a gallon, and on a fill-up , it equates to 2 dollars..
Depending on how much carbon build up you have 91 octane may not be enough. If the knock sensors detect this they will retard the spark, reducing power and fuel economy. Anyone who claims that a little knock
wont hurt needs to rethink their automotive skills. if that were the case we would not have designed the knock sensor algorithms.. and if you think that by having them you can push the car to knock because you are protected, you are sadly mistaken..

I don't mean to sound like we should all act like sheep and ALWAYS do what we're told. But sometimes it's just best to follow directions.
Sheesh! You think maybe us runflat users could get a smoother, quieter ride if we ignored the 30psi recommended by the factory and put in 50psi!?
Personally, I would never, ever buy a 'Vette from someone who had run regular gas in it for any length of time. I would be thinking; what other foolish things has he been doing to his car?

I know the owner of the local gas station would think a lot less of me for putting cheap gas in a car everyone dreams of owning. Supreme is for the Supreme.
Ditto with the oil, I would never ever consider putting even the best regular oil in my Vette. Not just because the manual says to use Mobile One, but because it's the best.
I waited a lifetime to own this baby and I want to put the best in the best.

Another thought.
We all give sage advice on questions to ask and things to check when new members are looking for a C5
A great question might be what gas do you run the car on?
I for one would not buy an LS1 thats been run all its life on 87 octane
This is one of those threads that really should be run regualrly because there are members out there who might be wrecking their engines through ignorance of the facts.

If that is a correct assumption, then I'm getting supreme @ pretty cheap prices. So why would I put anything but supreme in the tank in the USA?
I only use Chevron Supreme with Techron.

Forgive me if I am wrong, but isn't premium fuel in the UK running at close to $9.00 US a gallon?

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
