Here is an article on the topic:

The six road courses I've been on specifically say "water only, no type of anti-freeze allowed".....Some check it, some don't... For racing only purposes, it's a safety thing....in case of a ruptured radiator or busted hose, you'll spill everything on the track and anti-freeze on asphalt is about the same as engine oil, NOT GOOD!!!!!!!!!!!!!!!!

Have run thru it before and it ain't fun.........
