octane question

RE: octane question
The lt1 is a high compression engine, so you should be using the highest octane you can get.
With that being said, it really depends on how picky yours is. Some people can run 87 and everything is fine, while others will run mid-grade and get some serious knock.

To get the full potential of the motor you need to run premium (91 or 93 octane depending on your altitude). When you run 87 the car detects knock and starts to retard the timing, which in turn results in a loss of HP. It's your call.

I disagree... I can tell a difference even in my 3.8L motor... The engine runs and idles much smoother and responds much quicker. It's untelling what the difference would be in a high compression engine like the LT1

RE: octane question
You won't notice it as soon as you put it in, it will happen gradually as the ECU adapts to the higher octane and readjusts the timing accordingly, but it's not an instant change.
Bidicamaro: anything over regular premium fuel isn't going to get you any HP, running anything above premium on a motor that hasn't been modified to have a higher (11.5+) compression ratio or forced induction is just a waste of money.
