Yes! Biodiesel!
Biodiesel blends offer an immediate, practical, affordable response to the need to reduce emissions. For too long, we have relied on petroleum products to fuel our vehicles. And our dependency on pure petroleum diesel creates an even greater cost due to its exclusive use by the trucking, public transportation and other major commercial vehicles. But by responding the Federal and state mandates, business, government and the public can all benefit by making the change to biodiesel.
Biodiesel is a liquid fuel made up of fatty acid alkyl esters, fatty acid methyl esters (FAME), or long-chain mono alkyl esters. It is produced from renewable sources such as new and used vegetable oils and animal fats and is a cleaner-burning replacement for petroleum-based diesel fuel. Most importantly, biodiesel is nontoxic and biodegradable.
Many people don't realize that biodiesel nevertheless has physical properties similar to those of petroleum diesel:
| Biodiesel's Physical Characteristics |
| Specific gravity |
0.88 |
| Kinematic viscosity at 40°C |
4.0 to 6.0 |
| Cetane number |

| Higher heating value, Btu/gal |
127,042 |
| Lower heating value, Btu/gal |
118,170 |
| Density, lb/gal at 15.5°C |

| Sulfur, wt% |
0.0 to 0.0024 |
| Cloud point, °C |
-3 to 15 |
| Pour point, °C |

Like petroleum diesel, biodiesel is used to fuel compression-ignition (diesel) engines. Various blends of biodiesel with petroleum diesel also provide benefits.
