H2o and gas

67 Dart. The short answer to Austin and real Gas is no. We live in an area mandated by EPA to sell only gas with Alcohol. I fly large scale model aircraft and our engines are in the 100 cc class 2 cylinder 2 stroke varity and cost in excess of $1000.00 . Alcohol causes the bearings to rust and deteriorates the gaskets in the carburators. So when we were mandated to going to 10% Alcohol in our gas I started looking at doing something different. Being a ex-pilot I knew that av-gas did not contain alcohol, so I called a friend that keeps his aircraft located about 15 miles from where I live to ask him if he would pick me up some av-gas. When I told him what I needed it for he told me he had been washing the gas for his Cessna 172 for several years. His airplane is old enough that it likes 85-87 octane and not the 100 that is sold at most airports. He had his airplane certified for auto-gas by the FAA and has been doing this ever since.
