Which fuel is the friendliest to the environment gasoline, biodiesel or petroleum diesel?

produces the least pollutant (eg. soot).
my calculations show that gasoline produced the least amount of soot, after burning each fuel with a wick and collecting the soot. but after reading wiki, im in doubt. can someone please clarify?

    If you compare gallons burned, the gas would produce less pollution, but normally a diesel will produce more power from each gallon burned so it uses less fuel which produces less pollution per mile driven.

    For example, a Toyota Corolla gas will get about 38MPG. The same car with diesel will get over 50MPG, so it burns much less fuel and produces less pollution overall.

    The diesel engine also has the advantage that it can burn Bio-diesel as well. The gasoline engine cannot.
