Just recently I helped a friend flush his coolant system.He used AutoZones Valucraft coolant.All the ingrediants are the same as what is on Texacos label.The Valucraft coolant is distributed by Best Parts,Inc. Memphis,TN.Anyone ever heard of them?
Best Parts Inc. is just a name that Autozone uses when it doesn't want to put its name on a product. They are one and the same. That said, it's very likely that AZ gets Equilon to supply their antifreeze. Last I checked, there were only a small handful of companies in the US that manufacture ethylene glycol.
