I will not try it. I have a lovely Honda motorcycle piston with a dime-sized hole in the crown that tells me what can happen to your motor when you're consistently experiencing detonation.just out of curiousity has any one ran less then 93 or 91? i.e 89 or 87? if so what happened ? how was performance?
EVERY gas station that is worth buying from has 93 octane in SCI can only get 91 here in Utah but the altitude helps knock here. I can't wait 3 more weeks and I am moving to South Carolina, should have higher octane there, pluse 3000 feet lower be like driving and STi up here in the altitude WOOHOO!!!
They can work, but most of the on-the-shelf stuff is overpriced.
