Mercedes Engines and Biodiesel

Attached document covers the requirements for running on DIN EN 14214 compliant FAME.   Customer should be made aware of the oil change interval recommendations from Mercedes which are significantly reduced, and the requirements if the engine is stood down for a period of time.The quoted impact on engine power of 8% refers to a B100 mix so B30 will be much less noticeable. If they have a fuel supplier in mind already then a sample, or specification data would be helpful and we could seek a more specific comment from the OEM.In certain regions, diesel fuel according to EN590 or FAME fuel in accordance with ASTM D7467 isnot available but only fuels exceeding the maximum (ASTM D7467) biofuel content up to 30%.For engine types OM 906 / OM926 in Emission stage EM3a, the Service bulletin 2012-006 onDaimler -OEM-Powertrain-portal remains valid.In addition, we offer Code Option MK21 – ZPD unit pumps, which further reduces the Risk of Oildilution due to high FAME-content fuel up to 100% DIN EN 14214.It is necessary to monitor the Oil dilution closely with higher FAME content used.The oil change interval has to be adopted according to SI 2012-006
