There's a Sphinx near me that has 105 octane gas. Assuming money is no issue, what exactly would I need to do to run that high octane fuel in my GP, and can I put it in a stock '96 Corvette?

Put it in the car and drive it. Nothing special needs to be done or higher octane fuel. Your car will treat you special and thats about it.

Higher octane gas does not produce more power or give you better mileage.

The higher the octane, the higher the temperature and pressure required to detonate the fuel.


But its definitely good for bragging =)

make sure its unleaded tho or you will cause nothing but problems

It gives as much power as the type-r sticker on a civic, for a stock vehicle anyway.

I know all that. I was just wondering if I needed to do anything (like a pcm tune or something IDK) to run it is all.
Guess not?

You're good to go. But unless you are running into knock right now it's only going to drain your wallet quicker.

really high compression.

like 14:1 :p

but just make sure its not leaded gas!!!! if its unleaded than put it in and run it, our exaust will start smelling good to
if it has lead and u run it kiss ur cat, o2's, and a few othere things good bye

How much do they charge?

only benefit (stock) would be if you had knock from running too much timing. if you have a tuner, you can benefit from higher octane since it will allow you to run higher timing.

actually u can use an E85/prem mix since e85 is like 110/115 octane i think

I haven't checked since prices dropped. When they were still making my wallet cry it was around $5.50 or something outrageous like that.

Ya and you'll destroy your fuel system trying to run the E-85.

Not worth it.

As for the OP unless you tune your car for some serious advance on the timing what ever you pay over 92 octane is a complete waste of money.

Like was states above you need some serious compression to have any benifit of 105 octane.
