If yours are freezing in central Ohio right now, you have water in there, at least mostly water. I have the same setup as you (attached garage unheated) and mine have NEVER froze on me. I just use whatever blue stuff the store has, I always have. I bet if I kept it outside it wouldn't freeze. Actually it sits outside at work all day and no problems. I'm right over here in Indiana, so the weather is about the same as yours.
Yeah, like I said...just bought it 2 months ago, so I'm guessing the dealer "may" dilute their mixture and that's what got put in my reservoir....only speculating there though....lol
i guess i'm probably best off to get as much as i can out of it, then fill it up with the prestone.
thanks!
