Deisel can run on biodiesel without modifications... some modern engines can as well... here is a map to all the gas stations that have it... http://www.biodiesel.org/buyingbiodiesel/distributors/

it can also use vegtable oil from old fryers or resturaunts... that's a little harder... But still better than oil...
