Never heard of it, I know of HEET that soaks up water, but not something that takes out or changes ethanol.
Many quality oils have additives that help negate ethanol issues.
But some stations sell "boat" fuel that is ethanol free.
Whatever you do, only mix enough fuel to make a litre at a time, as soon as you mix ethanol gasoline with oil, the clock is ticking and it will degrade rapidly.
