Biodiesel is one of several alternative fuels designed to extend the usefulness of petroleum, and the longevity and cleanliness of diesel engines.
The ultimate goal is to contribute to building a stronger, more self-sufficient community by way of a community-based biodiesel production model.
However it should be noted that petroleum diesel fuel energy content can vary as much as 15% from one supplier to the next.
The lower energy content of biodiesel translates into slightly reduced performance when biodiesel is used in 100% form, although users typically report little noticeable change in mileage or performance.
Availability The presence of biodiesel pumps at fueling stations across the country grows daily. Pure biodiesel and biodiesel blended with petroleum diesel fuel provide very similar horsepower, torque, and fuel mileage compared to petroleum diesel fuel.
In its pure form, typical biodiesel will have an energy content 5%-10% lower than typical petroleum diesel.
Biodiesel provides excellent lubricity to the fuel injection system.
Recently, with the introduction of low sulfur and ultra low sulfur diesel fuel, many of the compounds which previously provided lubricating properties to petrodiesel fuel have been removed.
Biodiesel provides significantly reduced emissions of carbon monoxide, particulate matter, unburned hydrocarbons, and sulfates compared to petroleum diesel fuel.
Additionally, biodiesel reduces emissions of carcinogenic compounds by as much as 85% compared with petrodiesel.
