Changing the hoses and coolant in my son's 06 Dodge Stratus with the 2.4 turbo. It specs G-05. I have 1 gal of Zerex G-05. Mixed 50/50 with distilled water it will yield 8 qts. Cooling system capacity is 8.5-9 qts. I have 3 gals of Prestone all makes all models. Would you-
A. Use the Zerex and top off 1/2-1 qt with the Prestone
B. Buy another gal of Zerex and have 7 qts leftover
