Here in Kona we can buy non ethanol gas at the boat harbor. When the ethanol gas first came out it screwed up every ones outboard motors including mine (900 bucks worth) So last year out of curiosity I drove my landcruiser for two months on the non ethanol gas and got two mi per gallon more (12mi with ethanol vs 14 mi without) Unfortunately they charge you 25% more not two put the ethanol in the gas
