I keep a full tank over the winter and have never had any issues with the gas going bad or separating. I also treat every tankful with the green/ethanol Stabil stuff.

I also have an Evinrude e-tec. My service guy said that these engines are very forgiving of e-10. But if we go to e-15, we're screwed.

Well get ready for the screwing then...I know about a TV commercial recently produced at the Charlotte Motor Speedway featuring a well known NASCAR driver...the whole premise of the ad was to introduce E-15...brace yourself...it's coming...

If you can get the non ethanol fuel buy it. Ethanol does everything listed above. Plus you get worse fuel mileage. I use startron or lucas treatment if i run ethanol fuel.

Ethanol scrubs the white oxidation (aluminum oxide) off the inside of aluminum tanks and that sediment clogs fuel pumps. I never had a problem with it in my Evinrude 2 stroke, but my buddy had a helluva time with it in his Yamaha 4 stroke.

Sounds like the difference between fuel going through carbs and injectors...I think carbs would be more forgiving...the mist from an injector has to be pretty precise...
