In 2010, The California Air Resources Board (CARB) will be enforcing very strict clean air regulations for commercial truck operators operating throughout California.  Bio diesel is a "low particulate" emission fuel which is eco-friendly and thus will be in high demand due to its clean burning properties, better fuel economy and superior engine lubrication properties.
The benefits of bio diesel are enormous. Using B-20 grade bio diesel leads to a significant reduction in air pollution, increased mileage, and less wear and tear on engine components.  For example, a recent newspaper article in the San Francisco Chronicle, stated that Safeway Stores, a major grocery store chain have switched their entire 675 truck fleet from regular No.2 diesel to clean burning B-20 grade bio diesel.
B-20 grade bio diesel is a blend of recycled corn oil and low sulfur diesel fuel. Used corn oil is widely available in large quantities from the fast food industry and can be easily converted to bio diesel fuel.
