So typically my car is stored down south but I recently brought it up north, the windshield fluid that I put in a few months ago is rated for +32 degrees however the temperature in my area is gonna get to around 28 in the night. Should I be concerned? I was thinking of maybe getting some all season fluid and throwing it in there to lower the freezing point, would that work?
Put some low temp fluid in and run the washer for a bit to at least attempt to get things mixed in the tank and pump. If it freezes in the lines it probably won't cause an issue and will thaw once warm. If the tank is mostly full, you may want to run the washer to get the tank down to 1/2 way before topping off with the new fluid. I think you'll be ok regardless.
I say don't worry. If the temp is below 32 this time of year, it is only for a couple hours, not long enough to hard freeze. Adding to whatever is already in the storage tank is a plus!

I guess throwing in some all season fluid would work, but I agree with post 4 - probably not going to get cold enough for long enough this time of year to cause any problems.
