(1) Methods for testing S are based on the sulfur content in diesel fuel used for blending. Consult with the fuel supplier and ensure the correct method has been used
(2) Sulfur level must be per local regulations. Higher S levels may be used where allowed.
(3) Recommended cleanliness level for fuel as dispensed into the engine fuel tank is ISO 18/16/13 or cleaner per the test methods listed. Refer to the contamination control Chapter for more details.Note: Fuels that meet the most current revision level of "ASTM D6751" or "EN 14214" may be used for blending with an acceptable distillate fuel. The conditions, recommendations, and limits that are noted in this Biodiesel section apply.Referenced Documents
