Then you'll probably have to order it. What does it take, a little over a jug of Engine Ice to fill it up anyways? So you'll have to buy 2 jugs at around $20 a pop so you might at well shop around. Not less there is ATV dealers in your area, they might have it. Maybe they can order it for you and you won't have to pay for shipping.
I know that most automotive places carry Water Wetter additive so maybe if you want to settle for Water Wetter they can order a normal jug of that for you.
IDK what I'm gunna do without having a cycle gear near by when I move and can't use my military discount!!
