Buck, as a current small diesel driver amidst this whole dieselgate thing, I 100% feel your pain!
Also Ethanol is hygroscopic, meaning it sucks up water molecules from the humidity of the air. That's what makes it ruin seals and fuel lines n such. Our bikes are new enough that it's not much of an issue, but many small engines (mowers, trimmers etc) have real problems with it.
