I wish it was that easy around here. The last time I looked for Zerex the only place I could find it locally was Grainger. They usually only have a bottle or two on the shelf, so I have to special order it, and they only have the 50/50 prediluted mixture for around $12/gal. It actually works out cheaper to go online or buy genuine Motorcraft from the dealership at $16 - $17/gal.


I'm pretty sure that gold stuff is a HOAT (hybrid) extended life coolant, not that I really know what that means in practical terms, beyond what I've read around the web. I do know the subject of coolants is another online holy war of sorts.
