I was just wondering what everyones thoughts are on this topic.

Which fuel would help the performance of my ss sc more straight 93 octain or 94 octain with 10% ethenal?

Everyones input is welcome.

Thanx

 

Probably neither. Assuming you're getting no knock retard on regular 91 octane, putting 93 or 94 in it isn't going to get you any more timing. It'd be just like putting 91 in a car designed for regular 87 octane... won't do anything. Unless you're talking about a non-stock engine...?
