Steve, I just replied to this thread in the detailing forum. If I recall right, the parts guy at my local dealer, Knopf Automotive in Allentown PA, was not sure about what Winterwash was either.

I think the Summerwash may contain enough surfactants to work alone with a water mix, but I could be wrong. Since I live in an area that has subfreezing temperatures several months of the year, freezing is an issue for me. Actually I just let my independent garage fill my reservoir with Wurth brand fluid. Smells nice too

Has anyone recently used the concentrated stuff that GM used to recommend? I guess my only real concern / question would be how much alcohol or whatever antifreeze agent is in a winter concentrate, vs the cheapie generic washer fluid.

Perhaps a chemistry gury could chime in here? Somehow my hunch is that it would take roughly a pint of alcohol to reduce the freezing temp of a gallon of water to -20F, but I've been wrong before. Thoughts?
