I thought I remember ArcticFreeze 134a coolant being discussed here a few times but I could not find it in a search.
I picked up a can a Wally World today. Is this stuff any better than $5 a bottle 134a? Or worse yet does its claim to "seal" leaking gaskets and O rings equal something that may cause some problems to my system?
Looks like it has some oil in the can? Do I need to worry about the oil being compatable with the oil that is already in my system?
