        what's so illegal about using cooking oil in your car?
        \_ People who use biodiesel they make themselves (namely, poring in
           cooking oil) may potentially cause more pollution.  But
           the real concern is that the guvernment doesnt' get the tax
           on diesel, which is a lot higher in teh UK than the US.
