Jay, are you going to Oshkosh this year? I will be departing this coming Thursday. I like to get there early. BTW, I reread my Petersen STC and there is no requirement or recommendation that "every tank" of auto fuel be tested for ethanol. It does specifically prohibit ethanol, as we all know. One more thing, the word "mogas" is a misnomer. A motor is a mechanical device which converts electrical energy into mechanical energy. That terminology may be changing, however, with hybrid cars. One more thought: With the increase in the use of Ethanol, I would not be surprised if the auto fuel STCs are not modified to accept a blend of ethanol. Perhaps with some modification to the engine/airframe. One more comment, to the best of my memory: Back in the '80s, when I got my STC, our airport tried to prohibit refueling on the field. Someone call the FAA and the airport was told, by the FAA, that if they accepted federal funding, they could not prohibited fueling by individuals. The airport, however, was forced to provide a place, at their expense, for individuals to safely refuel their planes. So Jay, what day you arriving Oshkosh.

If there is anyting else that better illstrates the best use of a GA airplane, I don't know what it is -- 2.2 hours from Iowa City to Lake Superior!) (BTW: 90+ degrees, climb to 10,500 feet, cruise for over 2 hours on that horrible car gas. Dang, if it didn't run perfectly fine? Amazing! :-) Anyway, your airport CAN NOT prevent you from bringing car gas to fuel your own plane. They are violating the law by doing so, and you might point that out to your airport manager -- with a nice letter from your attorney? -- Jay Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" -------------- Original message from FlyboyEd@xxxxxxx: -------------- In a message dated 7/13/2006 10:05:29 A.M.
