I worked for a company around 2014, had the stc for mo gas, can only be done in a raven 1, fuel can’t contain any ethanol, must run a full tank of av gas once every 50 hrs and tell pax it’s running mo gas.
All that said would I recommend it? That’s a big fat nope, money is not the be all especially since it was the cause of massive detonation leading to engine failure.
