People mostly think that driving their cars or trucks on biodiesel requires them to make major engine changes, this is a misconception as your existing car can run on biodiesel without any modifications. The best you can add is a heating kit and that too if you live in a cold country.
Still a better option is going for a blend of biodiesel and petroleum diesel. Diesel engines are already up to 40% more fuel-efficient that gasoline engines and adding biodiesel to it makes them more eco-friendly as biodiesel emits 78% less carbon dioxide than petroleum diesel. Biodiesel blends are available in three different flavors – B5, B10, and B20. The number next to ‘B’ represents the percentage of biodiesel that is added to petroleum diesel.
Using any of the above mentioned blends needs no engine changes, however as a precaution, it is better to go for B5 or B10 if you are living in very cold climate since pure biodiesel tends to get viscous at low temperatures and need some sort of diluting before they can be put to use.
Ideally chose biodiesel that has been made from recycled oils, which consume a waste product, instead of those that are made from dedicated fuel crops such as corn or soybeans. The later type is not favored given the amount of industrial farming we have.
Biodiesel blends are provided by more than 1,000 stations across the U.S. and you can even use the internet to locate a station.
