I run distilled water and Water Wetter in my dirt bikes. My YZ400 was
especially prone to overheating until I switched to this mix. When off-
roading there's limited air flow (moving slow thru the woods) combined
with pushing your engine harder which makes for more heat. I also
added a lubricant to protect against water pump damage and corrosion.

This being said, I wouldn't run this mix in my Vanagon or any other
street vehicle (bike or car) as the 50/50 mix is more than adequate.
