Haven't seen any Peak phosphate free around hear. All the Peak I have found lists "corrosion inhibitors," and "proprietary ingredients." Now what the hell are those? At $7/gallon for premix one is paying $14/gallon for antifreeze, and if it's Peak, for what is arguably an inferior product by some folks lights. But if you know where I can get Peak that is phosphate free in Oklahoma, I'd like to know about it, just in case. Thanks, DMc
