Fueling & Injection - octane numbers

i just have a quick question. i fill up my car at a sunoco right next to my house. they offer both 93 octane and "ultra 94." is there any advantage to filling up 94 as opposed to 93? thanks

Stock heads/cam & compression probably not....you "might" lose a little kr on a really hot day at the track.....on the street not worth it.

cool. thanks for the reply.

wish they had that kind of stuff here all we have here in tucson is 91!

Just the 91 garbage here as well. There are a couple of 76 stations with race gas, I don't know the octane # though.
