Mine soaked over the winter. The gauge wasn't working in the Fall and was good again in the Spring (although not always perfect, hangs at 3 at times before dropping into blinking). Winter fill up was ethanol free if it makes any difference. And bike on center stand.
Had never used MMO before. The neighborhood shop was out of Sta-Bil and I remembered this member from Arizona who posts here quite often (cannot think of his name right now) highly recommending MMO, so I grabbed a bottle of it.
