They stated a 50-50 mix is 'best overall' protection whatever that means. Then on a separate chart they list the concentrations for 40, 50, and 60% and the freeze and boiling points are still dropping & climbing at the 60% level. So...I always used the RV stuff straight, undiluted.

Good point Poconos. I never have used the RV stuff, just the antifreeze from the pool company. I have always heard that you need to have a mixture of water and antifreeze or it will freeze. I assumed that went for all antifreeze. Well...you know what happens when you assume....
