by far the best explanation of what octane does for your engine i've ever read. With some rocket science thrown in!!

 

cthree - you da man....

 

i usually use 91

on specific days when i feel like im big balling i'll use 94

 

Funny thing, just today my wife did me a big favor and filled up my tank; with 87!! Now I've got 12 gallons of garbage in my tank I need to find a way to burn off before my next track day so I can put some 91 back in there. What a drag. It wouldn't be a big deal if it didn't take me a month to use up a tank of fuel on the street. Oh and I got a speeding ticket too, great

 

I gave this a try last year just to see what it would do. Ran the tank down and filled it with 94. Didn't feel a damn thing and I'm supercharged. Didn't hurt anything but didn't see any difference in fuel mileage or performance. Total waste of money.

believe it or not, from the tests done, NOS octane booster gives you the biggest boost in octane points. I think upwards of about 3 points or so.
