According to owner Doug Odell, they have seen no difference in the performance of their two diesel-powered delivery trucks since switching to biodiesel (B20) a year and a half ago.  The fuel has performed well year-round in cold Colorado temperatures. Odell said using biodiesel “not only helps to reduce our dependence on foreign oil, but because our (biodiesel) supplier contracts with local farmers for oil seed, helps the sustainability of Colorado farmers.”
