I personally wouldn't try to mix anything in my gas except for a small amount of Marvel Mystery Oil for a top cylinder lube or Sta-Bill for storage. Playing with chemicals that could potentially damage an engine or any of it's components could be very costly and possibly have disastrous results. It is a science within it's self and should be done in a lab equipped for such experiments. I know in racing, especially drag racing, it has been done quite frequently, but that's another story and some definitely with drastic results! JMHO.
