Hey, I already have a post here asking for some oil advice so I was thinking to ask for some coolant advice too. I have a Subaru Legacy IV and no coolant history so I am thinking of changing it out. Since the car has 125000 miles on it I was looking at the Valvoline MaxLife coolant which seems to be a good fit and should last 5 years.
Now researching I came across Peak Global Lifetime which seems to be highly recommended and also would be a lifetime fill if I change out all the old fluid (which I plan on doing). I know it's recommended to change the coolant just for the peace of mind, but the idea of being able to almost not have to think about the coolant ever again is very tempting.
How good is the MaxLife coolant in my application? How good is the Peak coolant in my application? Should I chose one over the other? And is the Peak coolant really a lifetime fill?
