The stuff does not seem to evaporate much at all, it doesn't freeze (where the saw is located is unheated), and it has corrosion inhibitors so the saw doesn't rust and it doesn't go bad or get stinky and it is safe to drink in small quantities (seriously). I have never changed it. Some dribbles away while cutting and I just keep refilling the tank. I use it at full strength and it is around $2.50 per gallon in the US when it is on sale.
