GM Dex Cool -----orange color----Oreilly
Toyota Long Life coolant------red/pink----$21 at carquest
Prestone Ext Life any color ------color kinda clear ---Wally world
Least expensive coolant branded for retailers -------yellow/urine color
Anyway I am considering using prestone ext life coolant(any COLOR) for my 04Prius!
Prestone 800 phone hotline say this is compatible for that application.
Local ASE mech says the same.
I have notice many Toyota owners have been sold on mfg dealer branded products and color dye agent.
