[QUOTE=IanY;3288750Pentosin is Ethylene Glycol, and is toxic as can be. I'm sure you knowthat Proplyene Glycol is used in Nascar (and almost all GT car racing) because its a whole lot safer to the driver when it leaks out.[/QUOTE]


Actually if you do some looking at NASCAR track rules you will find quickly that the use of any type of antifreeze will result in a one race suspension. The reason is simple: antifreeze is slicker than snot on a track and uneccesary to boot, the use of it will invariably end with it on the track and far more wrecks. Several additives are currently allowed though.

Antifreeze is the last worry on any drivers mind as a substance that might get splashed on him/her. I can't think of any time I saw engine coolant splashed on a driver...Burning fuel I have seen though!
