I have been looking for someone who can substantiate the claims from Water Wetter .... so, when you run your car without it at the exact same water to coolant ratio, it runs hotter?
There has been a lot of discussion on WW on this site and others ... and, there appears to be no independent test data - and, there also appears to be a large number of people who simply don't believe the claims ... so, your experience, if providing an audit trail of some sort, would be very helpful.
Most everyone that is a supporter has done SOMETHING to their cooling system WHILE they were replacing coolant (in addition to WW), that generally invalidates testimonials. If you have simply (and ONLY) replaced your coolant mix with a mix that includes WW and it changed the operating characteristics (i.e. it runs cooler) it would useful to all.
