Talked about it but now finally getting around to flushing coolant in my 17 Outback 3.6. I'm using Pentafrost A3 (have 3 gallons) and I picked up a 2 pack of Subaru cooling system conditioner. The size of each of the 2 bottles is 125ml. Am I supposed to use 1 of the 125ml bottles or both? I assume 1 bottle per flush as that is common sense to me but I don't like to assume when I don't know. I bottle or 2 boys?
