What is biodiesel?
Biodiesel is a renewable fuel that is predominantly domestically produced. It can come from various sources including animal fats, new and use vegetable oil, soybean oil, and restaurant grease.
Biodiesel can be utilized in vehicles in either its pure form or as a blend with petroleum diesel. Pure biodiesel, 100% biodiesel fuel, is referred to as B100 where as a blend of 20% biodiesel and 80% petroleum diesel is labeled as B20. B20 is the most common biodiesel blend in the United States; other common blends include B5.
Blends up to B20 may be used in any diesel engine manufactured after 1993 with little impact on performance. Most original equipment manufacturers (OEMs) approve the use of biofuel blends up to B5 in their vehicles without voiding parts or workmanship warrantees. Please check your OEM’s website or contact your dealer to determine what types of biofuels should or should not be used in your vehicle.
B20 and lower-level blends of biodiesel have not shown to have negative long-term effects on engines. Biodiesel has a higher lubricity than traditional petroleum diesel and thus can reduce the wear and tear on engines and, in some cases, extend oil change intervals.
What are the benefits of biodiesel?
While biodiesel has many similar characteristics to petroleum diesel, it burns much cleaner, is biodegradable and non-toxic, making it overall safer for the environment and human health. The burning of biodiesel creates fewer emissions of CO2 particulates, and other polluting compounds in comparison to regular diesel fuel. In addition, because it is both biodegradable and non-toxic, there is no possibility of it contaminating the soil or water as normal diesel can.
