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.

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