They sell this at a gas station near me. Was wondering if you could run this in the corvette? Is there too high of octane to run in stock engine? Just wondering who would use this since there is no race tracks near by? I know there is a lot of exotic cars in this area. Not that I would pay $10/gal... lol. But I have noticed that it's been this price for the last couple months and is probably maxed out on this pump. Regular 91 octane is north of $7/gal now, figured if it gets close to $9+ per gallon, why not put 101 in if it's going to be around the same price?

No point. Genuinely pouring money down the drain running that on a car that's not tuned for it, and you wouldn't tune a car for that unless it had high enough compression to warrant it.

91 octane is more than $7/gallon? That’s nigh on to double Florida hurricane pricing.

Going with a higher octane than what the car is tuned for won't get you anything. In theory you could re-tune the car. However, the gains that you would see on an otherwise stock C5 really wouldn't be worth the cost. Also, to put it in perspective, I have 500HP at the wheel, and I run 93 octane. You really don't need 101.

Octane ratings are merely a reflection of resistance to knocking, primarily heat related. In actuality a less than optimal burn is achieved with too high an octane rating for it effectively cools the combustion chamber below the ideal temp.

Like said, will not give any performance boost. Does smell good though... I ran 116 octane Turbo Blue in my old Harley dragbike, with 16.1 comp it needed it. Whatever I didn't use during a race weekend I would run in my lawnmower. Can't say it cut any better but it did smell like the racetrack and that gave me a smile as I mowed.

One thing to consider - it probably does not have the additive package that modern engines need for long life.

As to fuel prices - read this and weep....

Couldn't agree more! Running higher octane than the engine needs (or wants!) with no other mods or adjustments will actually cost power and fuel mileage. One way to look at super high octane fuel is, in my laymans terms (meaning how I understand it) is premium, high octane fuel doesn't explode/ignite as easily as regular, lower octane fuel does. I personally know someone who had run premium in his 5.3 Chevy Trailblazer (not the 6.2 SS model) since he bought it. He read an article about this very subject, and switched to regular. He came to me and told me that he couldn't believe the difference in response and he picked up 2 or 3 miles per gallon, as well. Moral: DON'T RUN PREMIUM IN A VEHICLE THAT IS SUPPOSED TO RUN REGULAR!!!

Not really going to do you any good running octane that high unless you have extensively modified your engine.

To all the nay sayers 101 with a tune will give better performance . Be ready to replace 02 sensors more frequently. Without a tune you're wasting money.

I don’t think anyone is bashing 101, just the possible benefit with a stock setup. Adding timing, advancing the cam for increased cylinder pressure, or thinner head gaskets for more static compression might benefit from higher octane. Might. In any event the above changes are moving on from stock…

Compression is compression, what it calls for it will be fine, In Canada the 94 Chevron does not have ethanol only advantage or not depending on who you talk to
