Biodiesel Best Practices

Using Biodiesel

Biodiesel can be used in any diesel engine. It can be used as a “drop-in” to fully replace petroleum diesel, or blended to any percentage. B20 blends, consisting of 20% biodiesel and 80% petroleum diesel are commonly used across the United States.

As with all liquid fuels, proper management of your assets helps ensure you have the best experience with the product. We recommend the following best practices for maintaining the quality and integrity of your fuel:

Quality Control

Any biodiesel you use should meet the current ASTM D6751 specification to ensure it is safe for use. Additionally, we recommend you purchase your fuel from a BQ-9000 certified producer or supplier. BQ-9000 is a third party quality assurance program that requires participants to document that they follow industry standards for storage, sampling, testing, blending, shipping and distribution. SeQuential is a BQ-9000 certified producer and marketer.

Storage and handling guidelines for biodiesel are essentially the same as those for petroleum diesel.

  • Turn tanks every 6 months
  • Clean tank collars every 6 months
  • Stick tank to measure water content once every 6 months
  • Be mindful of cold weather:
    • Replace B99 with a B50 blend when temperatures fall below 50 degrees
    • Treat B20 blends with a winterizing agent when temperatures fall below 25 degrees
    • When temperatures are consistently below freezing, follow the same anti-gelling protocols you’d follow for petroleum diesel, such as using tank heaters or adding winterizing agents
