I just read in Autoweek mag Jay Leno's essay on the evils of ethanol. In my 300F I have been running a mix of 100+ octane leaded aviation gas and pump premium spiked with the normal amount of ethanol. Has anybody in the Club experienced any problems with today's ethanol-infused gas? Jay talks about rubber parts (in fuel pumps, for example) being eaten up and ensuing engine fires. Terry McTaggart
