ground effect,
Let's not start another urban myth here. For the record, turbines burn almost anything that is clean and hydrocarbon, generally without the ill effects that you list. The biggest problem that turbines experience when they burn gasoline is lead deposits on the hot section, which limits the time you should burn the gas. Metering, stall protection, temperatures are all very well controlled with different fuels in a turbine. Starts have to be manually controlled, generally but performance is unaffected, and the range might be less only because less fuel mass fits in the gas tank, and for no other reason.
