: In the fifties farmers would burn something we called "Powerfuel" in

My dad's 1939-ish Oliver-60 Row Crop (that he still uses to plow snow and
run
the PTO pump for the logsplitter) was one such creature. It would run on
either gasoline
or kerosene ("farm-fuel" is what I'd heard it called). That tractor's a
hoot to drive
around.

Through rush hour traffic, no doubt! ;~)
