This is a completely legal conversion as long as you do it right and Evirosafe has no Biologically harmful side effects either! 
Your going to get much better performance form your engine as well as an improvement in fuel economy too since ES 12 operates at lower pressures and it takes less of it! Your compressor will also love it, it's not having to work as hard to do the same job and ES 12 requires a lot LESS horsepower or Killowatts to cool!
