Zmax

I was watching an infomercial about ZMAX, they say your car runs cooler and better. Has anyone tried this stuff?

Well, considering the Tornado was a product of infomercials.........



I'm going to call BS.

I'm not 100% sure as I haven't seen the infomercial, but I think it's similar to Red Line Water Wetter. Water Wetter does lower the water temp by about 10 deg F on a not day, but unless your water temp is over about 200 F to start with, it's not going to make much of a power difference.
