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
