I am using valve tec in Fl.My reason is If I can get non-ethonol, For a little more than ethonol plus the additives, I would be nuts not to use valve tec since they already put good stuff in the gas.AND NOT CORN!It is also higher octane than most would buy.My guy says other than the condensation issue, it can stay in the boat a year without hurting anything, motor wise. :shock:
