Always ensure that the biodiesel used in fuel blends meets the latest ASTM D6751 specification. ASTM D6751 is based on the physical and chemical properties needed for safe and satisfactory diesel engine operation and ensures the quality of biodiesel.

The BQ-9000 program, an added level of quality assurance, ensures that producers are following industry standards for storage, sampling, testing, blending, shipping, distribution, and fuel management. SeQuential is a BQ-9000 approved and certified producer and marketer. All our fuel also meets ASTM D6751 guidelines, so you can feel confident in its quality and safety.

Biodiesel is a considered a “drop-in” fuel meaning that it can be used in any diesel engine without modification, and you may fully replace petroleum diesel with 100% biodiesel or biodiesel blends.

B20 (20% biodiesel and 80% petroleum diesel) is the most commonly available biodiesel blend in the U.S. This ratio delivers a good balance of cost, emissions, performance, and compatibility, and is ideal for most consumers.

Engine warranties do not usually specify types of biofuels to use in an engine. However, biodiesel blends up to B20 are widely supported by engine OEMs. View an updated OEM support summary and additional OEM information from the National Biodiesel Board website.

Guidelines for the storage and handling of biodiesel are comparable to those for petroleum diesel and require the same level of care.

Make sure tanks are free of water, sediments, and other contaminants. In general, B20 tends to have a longer storage life than B100. Heat and sunlight can accelerate oxidation, so clear totes are not advisable. Exposure to oxygen reduces storage life. It is best to use biodiesel fuels within 6 months – take precautions for long-term storage like using nitrogen blankets and/or stability additives.

• Follow the same anti-gelling protocols used for petroleum diesel
• Treat B20 and higher blends with a winterizing agent when temperatures fall below 25 degrees
• If using higher biodiesel blends when temperatures are consistently below freezing, consider using a tank heater
