Genetic engineering could improve biofuel performance — Introduction of novel oil traits through genetic engineering is under investigation as a way to produce industrial products in oil seeds, such as soybean. It has been suggested that oil high in oleic acid and low in saturated and polyunsaturated fatty acids can enhance overall performance. Researchers have identified what they term a "soybean event" that has about 85 percent oleic acid with a "concomitant reduction in both saturated and polyunsaturated fatty acids."

Reducing emissions still a challenge — One of the problems with introducing more biodiesel use for transportation is the observed increase in NOx (nitrogen oxides) emissions, compared to conventional diesel fuels derived from petroleum. Tests in a light-duty diesel engine of a hydrogenated biodiesel fuel with a higher percentage of oleic acid methyl ester and less linoleic and linolenic methyl esters demonstrated a decrease in NOx levels in some engine modes and an increase in other modes.
