I read this article early on. They have worked on the problem....I didn't use that type, but I am pretty sure they have a handle on the problem according to my local Chevy rep. My neighbor owns a dealership nearby...so I talked to a few of his guys.... He stated, they are having problems with just about all of the anti freeze that comes into the used car department. So, they just empty, flush and put in new for all the used cars with warranty... He said it isn't worth the risk for no more that it costs...
