Ferruccio Lamborghini's Tractor

Origin
Ferruccio Elio Arturo Lamborghini (1916 - 1993) was an Italian industrialist who started with tractors before eventually turning his business into high-end sports cars. In 1947, Lamborghini, returning from the war, saw the need for agricultural and industrial revitalization. Using parts from abandoned military vehicles he built his first tractors. These tractors were based on the six-cylinder petrol engines of Morris trucks. However petrol (in Italy at least) was prohibitively-priced. Lamborghini augmented the engines with a fuel atomizer of his own creator which allowed diesel fuel to be used instead.

Effects
Turns normal diesel into the more expensive petrol.
