What octane do I need to run for a 10 to 1 engine? I've been putting 93 or 94. I have a station that has 100 if I need it, but I'd rather build an addition on my home... Also, the 94 I was using (and the 100 I have available) is sunoco. I keep hearing their gas is crap, so am I better off with someone else's 93 or sunoco's 94? I just want to make sure everything else is up to snuff before i start looking to get more out of the setup... Thanks! Mick
