There are a number of advantages to using biodiesel. Biodiesel is more viscous than diesel and it is a better lubricant for reducing fuel injection wear. Biodiesel has almost no sulfur emissions, has a higher boiling point, and low vapor pressure. Biodiesel and water do not mix (i.e., are immiscible). Biodiesel vaporizes at a lower temperature (>130 degrees Celsius, >266 degrees Fahrenheit) than diesel (64 degrees Celsius, 147 degrees Fahrenheit) and gasoline (minus 45 degrees Celsius, minus 52 degrees Fahrenheit). There are also a number of different blends of biodiesel, listed as a B followed by the percentage of biodiesel it contains. For example, a B100 blend means that it is 100 percent biodiesel and no diesel fuel. A B2 blend would have 98 percent diesel and 2 percent biodiesel, and a B20 blend would have 20 percent biodiesel. These blends enable biodiesel to be used in various diesel-operated automobiles and equipment, such as diesel-based generators, most marine vessels, and even diesel-operated all-terrain vehicles (ATV). It can also be used for heating oil with a B5 blend.
