IJ>Does anyone have any (reasonably well documented) examples of cases IJ>in which commercial airliners have been refueled with unconventional IJ>fuels? Gasoline? Diesel? Alcohol-containing fuels? What do the engine IJ>operating manuals allow? I recall a chart in the ops manual for a P&W PT6 powered turboprop (if memory serves me, it was a Beech 99 Airliner) that stated the number of hours the turbine engines could be operated on gasoline without requiring any special maintenance procedures. As I recall, it was something like 8 hours, which seems sufficient to get one home, or at least, to an airport with jet fuel. An altitude limitation also applied. I also recall conversing with a pilot who flew Mexican charters in the BE99. He told me that he once had to fill the tanks with Tequilla to depart a Mexican field that had run out of fuel. While I believe that a PT6 would run quite well on Tequilla, I have my doubts about the story. After all, the hour was late and the stories were becoming exagerated. Whether true or not, I doubt the tale is "reasonably well documented" anywhere, other than a stray service bulletin about a worm clogging a fuel line.
