I have seen 111 octane he in S.D there are many poeple putting this race fuel in thier cars. It is leaded they mix 1/2 & 1/2 and use it only for drag days. Another guy I know runs it staight in his 2004 mustang daily driver and has done so for quite some time now. Do they make unleaded race fuel? and where to get it?
