Is There a Difference between Biodiesel And Diesel

When it comes to fueling vehicles, the choice between biodiesel and diesel is an important one. While both fuels serve the purpose of powering engines, there are key differences that set them apart.

Diesel Fuel

Diesel fuel, also known as petrodiesel, is a traditional fuel made from petroleum. It has been the primary fuel for diesel engines for many years. Diesel fuel contains sulfur and carcinogenic benzene, which are regulated by state emissions boards and the EPA.


Biodiesel, on the other hand, is a renewable substitute for petroleum diesel. It is domestically produced, clean-burning, and environmentally friendly. Biodiesel is nontoxic and biodegradable, making it a preferred fuel type for the U.S. government.

Key Differences

One of the key differences between biodiesel and diesel is lubricity. Biodiesel has higher lubricity than diesel, especially ultra-low sulfur diesel. This higher lubricity reduces wear on engine parts and contributes to longer overall engine life.

Another important distinction is emissions. Biodiesel produces lower emissions compared to diesel, which aligns with the national goal of reducing reliance on petroleum and promoting cleaner fuels for a healthier environment.

Can Biodiesel be Used in a Regular Diesel Engine?

While most diesel engines are not specifically designed to run on biodiesel, the two fuels are similar enough that they can be used interchangeably. Biodiesel is considered a replacement fuel for diesel engines, offering a renewable and cleaner alternative.

Renewable Diesel vs. Biodiesel

Renewable diesel is another alternative to traditional diesel fuel. While not identical to petroleum diesel, renewable diesel is considered a “drop-in” replacement for petroleum diesel. It offers similar benefits to biodiesel in terms of reducing emissions and promoting sustainability.


In conclusion, biodiesel and diesel have distinct differences in terms of production, environmental impact, and performance. Biodiesel offers a renewable and cleaner alternative to traditional diesel fuel, with benefits such as lower emissions and improved lubricity. While most diesel engines can run on biodiesel, it is essential to consider the compatibility and potential advantages of using biodiesel for a more sustainable future.
