What Octane Do You Use?

correct me if i'm wrong, does higher octane gass actuatlly convert from a liquid to a vapor much slower than regular gass to prevent knocking due to a higher compression?

correct. higher octane has less power //content.invisioncic.com/y282845/emoticons/clap.gif.178cba2c538c68e720c727fcb024b19c.gif

I run 93 because I got my timing advanced to push out every bit of extra hp from 93 gas. Kind of sucks now when I am trying to not spend a lot of money though.

89 is all thats required on my engine. Any higher and I just waste money...

90 (contains ethanol though) because I can get it for the exact same price of 87. 89 is what's recommended.

I work in tech support at an oil refinery and its a waste of money using a octane higher than what your engine is rated for. As long as your engine dosen't knock your fine. Here's a link that may be helpful.

if there was a gas station that sold a 60/40 blend of water and gas for a lower cost, i would probably use that.

Agreed! All that high octane is going to do is help reduce knock, if you have any. If your car runs a lot better after putting high octane in, perhaps your car WAS knocking, and the ECU was pulling timing or something...
