According to the Maui News biodiesel is the cheapest motor fuel available there. At $2.29 a gallon it is $.10 cheaper/gallon than regular unleaded (the price difference is not pointed out in the story but unleaded is currently selling for $2.39). The biodiesel there is a blend of used cooking oil and diesel. Interesting story.
