What can I use for injection?

I am sure this has been asked before. In winter it can get to single digits, so i need something that will not freeze. I tested 50% alky and 50% water and sat it outside. It did not freeze. So I can use that...

I have heard of people using washer fluid. I should not get the ones that foam when you shake the bottle.

Does anyone here use washer fluid? If so, what and where do you get it?

Well, this should be in the other section... Sorry.
