Anything to about 104-105 is unleaded. The 100 octane is perfect for N/A and most F/I applications to a certain hp. You really dont need 110 because it burns so much faster and hotter, you won't gain much more over 100 octane.

Just pour straight 100 octane, or just mix 91 with the 110 and you'll be fine.

 

sweet....next season though, im in chi. and winters around the corner.
