Looking to flush the coolant on 916, i found a page on here regarding using Ethelyn Glycol 50/50 is this ok to use. I have a gallon of G48 Ethelyn Glycol (and also gallon de -ionised water) and a gallon of G12 - Monoethelyn Glycol premixed, save me hunting around in the depths of wales for more ? Not thinking of mixing just looking for conformation that either are suitable to use. Thanks Pat
