At my new home on Virginia's Eastern Shore, I have found a gas station that sells pure gas, no ethanol at all. Does anyone know if it would be a problem to add this gas to a tank with E10 in it? Are there any issues by using pure gas in an engine that has run E10? If I do use pure gas and then go on a trip in the boat and have to use E10 there, is that an issue? I would love to use the pure gas to eliminate the hydroscopic problems associated with E10 but am worried that changing horses midstream is not a good idea.
