I am lucky enough to have at least 4 stations selling ethanol free within 12-17 miles of me. Most of them do charge a premium of about 30 cents per gallon for it. The Shell station sells it as Marine grade for around $1+ premium above regular no lead so I assume it is highest octane along with ethanol free. I haven't tried it yet for my 2 cycle stuff. I use the regular grade non-ethanol for my mowers and generator and have had no problems with it.
