On the other hand, NASCAR allows the use of Propylene Glycol based coolants. It dissolves easily with water and is non-toxic. AMSOIL Antifreeze & Engine Coolant is formulated with propylene glycol.

Indeed, the Evans Coolant is NHRA approved.
Also, Summit Racing has a non-Glycol-based coolant specifically for racing.
You can also run distilled water with two bottles of a wetting agent such as Redline Watter Wetter, Royal Purple Ice, or Pro Blend Below 40.

We always added 1/2 a bottle of this stuff with straight water. Kept everything looking new inside.
