Where on earth are you guys getting your elc? Ive been to all the local truck stops and repair centers and no one has concentrated. Even went to international. Everyone has 50/50 and they look at me like i'm an idiot when I tell them I NEED concentrated coolant. Ive looked everywhere I can think of online, 2 places had it. One I had to buy 6 (I need 4) and one place half their website was down and wouldnt let me add it to the cart or check out. I just need to order 4 gallons of concentrated elc, not brand partial.
