Operating with Biodiesel

  • Stories From the Field
    Performance On The Road
    Use biodiesel with confidence. Major U.S. vehicle manufacturers approve use of biodiesel blends up to 20 percent in diesel engines. Biodiesel offers consistent performance and contains higher cetane levels than regular diesel fuel for enhanced power.

    Seek Out BQ-9000
    All biodiesel must meet the ASTM D6751 standard to be legally sold at retail fueling stations. The National Biodiesel Accreditation Commission created a voluntary accreditation program – BQ-9000 – for biodiesel producers and marketers. Purchase biodiesel from companies with the BQ-9000 designation to ensure the highest quality fuel.

    Cold-Weather Operation
    Biodiesel is an all-weather fuel, operating successfully in both summer and winter months. As with any fuel, proper treatment during cold weather is critical. There is no significant difference in cold-weather treatment between #2 diesel fuel and biodiesel blends up to B20.

    Storing Biodiesel
    Regardless of the fuel you use, storage tank maintenance is important for trouble-free operation. Avoid temperature extremes and keep water out of storage tanks. Water can corrode fuel systems and promote microbial growth that damages fuel quality. Prevent water condensation by keeping tanks full, especially when temperatures change from day to night. Use stainless steel, aluminum, Teflon® or fiberglass fuel storage tanks.
