| What is biodiesel? |
| |
Biodiesel is an alternative fuel source, produced from natural substances (such as regional corn crops), that is both biodegradable and environmentally sustainable. Typical blends of biodiesel fuel include B2, B5, B10, or B20. The B factor states the amount of biodiesel in any fuel mix. For example, fuel containing 20 percent biodiesel is labeled as B20.

| Can biodiesel be used in standard diesel engines? |
| |
Diesel engines require a few modifications to run on biodiesel fuel blends:
- The biodiesel must meet the minimum specifications for the country in which they are used and should only be purchased from recognized and authorized diesel fuel suppliers.
- In Europe, biodiesel fuels must comply with the European Standard EN14214.
- In the United States, biodiesel fuels must comply with the American Standard ASTM D-6751.
- Without proper alterations, biodiesel can harm fuel system components, primarily hoses, pump seals, and filters.
- Biodiesel gels in cold conditions, similar to petroleum diesel fuel. Higher biodiesel blends typically gel faster, although biodiesel blends up to B20 require the same fuel management as petroleum diesel.

| Known issues |
| |
While there are many advantages of biodiesel, be aware of some potential concerns:
- At temperatures below approximately 5°C (41°F) ambient temperature, a fuel heater may be required. Higher-viscosity fuel, from cold temperatures, may result in fuel delivery problems, such as injection pump seizure and/or poor injection nozzle spray atomization.
- John Deere recommends using only the fuel hoses listed in the parts catalog for the machine being repaired or serviced. Use of other hoses from different applications within John Deere or from outside hose suppliers may not be compatible with biodiesel fuels.
- Biodiesel fuels should be purchased only from recognized and authorized diesel fuel suppliers.
- Even biodiesel fuels that comply with a suitable standard as delivered require additional care and attention to maintain the quality of the fuel in the equipment or other fuel tanks. It is important to maintain a supply of clean, fresh fuel.
- The National Biodiesel Board (NBB) is the national trade association representing the biodiesel industry as the coordinating body of research and development in the United States. The NBB's direct phone number is 1-800-841-5849 and their Web site is www.biodiesel.org.
- John Deere will continue to monitor available information on biodiesel products. Future testing of different fuels may be done as their popularity increases.
- Painted surfaces may be damaged by biodiesel fuel/blend contact.
- Any on-site fuel tank must be equipped with a 10-micron (or finer) filter.
- To maintain fuel quality, no more than a 3-month fuel supply should be kept on-site.
- Biodiesel concentrations of 5 percent or lower are recommended for winter (or cold weather) operation. As with a 2D petroleum-based fuel, blending with 1D fuel and/or cold weather additives (pour point depressants) is required.
- All seals, hoses, gaskets, and wire coats must be monitored as they may swell, crack, or become tacky over time.
- Following the conversion of a unit that has previously run on petroleum/diesel-based fuel, one or two instances of premature fuel filter plugging can be expected. This is caused by the dissolution and washing of fuel deposits into the filter and is considered normal.
- Aging and oxidation lead to increased acids and the formation of gum that may plug the filters.
- Biodiesel should not be left in the system. If product is going to be stored for more than 3 months, drain the fuel tank and lines to the engine, put in a sufficient quantity of petroleum diesel fuel, and purge the engine of all biodiesel.
