Octane points matter . 91 is not 93
93 new = 98+ old
91 new = 95 old
European nations still use the old octane method if anyone needs to do a google compare

I've also noticed that in humid areas like NC, these engines seem to do better than in arid areas like mine. Also, when out of state this past summer, my '67 sure liked the pure gas I was able to get without ethanol. No issues, even at high elevations of over 8000 feet.
