While sampling blended biodiesel fuels purchased from small-scale retailers, researchers at the Woods Hole Oceanographic Institution found that many of the blends do not contain the advertised amount of biofuel.

Cleaner engines, cleaner air and more uses for local farm products were the focus of a just-completed study of biodiesel as an alternative fuel source on selected Ontario farms. This province-wide initiative is the only one of its kind in Canada. It involved six farms to evaluate the effectiveness of using biodiesel in agriculture.
