Jason the reason you may not have found much support for Evans is possibly that most people resist paying big bucks to fill their engines with flammable coolant for benefits that don't make much sense to the average driver.
If millions and millions of cars get by on regular fluids, you can either join the herd or strike out on your own despite the fact lots of people don't see the value. The only thing I'd advise you not to waste your time doing is trying to convert the herd. Spend what you save by using normal coolant on extra fuel. Those 'free' miles of driving will put more fun in your life than any amount of Evans propylene glycol elixir.
Moo...
