Vehicles using biodiesel blends have logged millions of miles, including three one million mile tests.  In these tests, performance, fuel mileage and drivability with biodiesel blends were similar to conventional diesel, except opacity levels and exhaust odor were less offensive.  The exhaust smells similar to French fries.  No adverse durability or engine wear problems were encountered.

No special facilities are necessary to blend biodiesel.  It blends easily, stays mixed and requires no special handling.

Biodiesel operates compression ignition engines.  According to preliminary studies conducted by certain engine manufacturers, no engine modifications are needed for blends up to B5.  There are no standards at present for engines using up to B20, but some are being proposed.

No special storage is needed.  It can be stored wherever petroleum is stored, except concrete lined tanks.

Biodiesel reduces emissions significantly.  Compared to petrodiesel fuels, biodiesel substantially reduces emission of unburned hydrocarbons, carbon monoxides and particulate matter.

Biodiesel reduces U.S. dependence on foreign oil - positive energy factor.  Every gallon of biodiesel has the potential to extend oil reserves by four gallons.  This is because every unit of fossil fuel used to make biodiesel results in a 3.2 unit energy gain and petroleum diesel has a negative energy factor of .88.
