Yes, another affirmation...WaterWetter DOES work. I had it in an '88 Accord LXi that I gave to my brother a few months ago with 274k...car still runs as new, the motor's never been apart other than routine valve adjustments, and it's always been on WaterWetter. In that car, I did it primarily for the enhanced corrosion protection that is offered, plus it allowed me to downgrade the gas I was using (from Premium to mid-grade) I figure primarily because it kept the motor's hot spots cooler.
Now I run it in both of my Benzes, and it's brought down the temp about ten degrees C. in both cars. Give it a try, and good luck!
