Actually, I've used it and still have a leak from the right side head. Also, as far as I know, it was only DOHC 2.5 Subies that had leaky heads for a while, not all of them-certainly not my neighbors 2.2 with over 300K miles! I only used one bottle of the "coolant conditioner", maybe I should dump another one in there-it was only $2.50 a bottle.
