1. I thought Engine Ice was AMA approved, and that's a PropGlycol product?
2. Amsoil is a sponsor of EBR. Ostensibly they run it. I also know what they recommend to those of us who had super-stock motors built by them. It wasn't Amsoil. At the time, they didn't have enough race experience with it to recommend it, so they told me to run Motul 300V. That may have changed.
