technical question about 2 stroke fuel, I have asked numerous people what is the proper fuel to run in my rotax engines, where I live you my only options are 93 octane premium gas that has 5% ethanol or 90 octane non ethanol fuel, I have heard horror stories about running them both, i would really appreciate a correct reply, can I use the ethanol free 90 octane safely without harm to my engine, can i add octane boost at the proper ratio, can i mix 110 octane av gas with the ethanol free to make a 93 octane fuel or does the 93 octane prem gas with 5% ethanol be ok, I have asked this question before on this forum and never got a reply, please, I would love the correct answer.
