Diesel fuel with a FAME content of max. 5% in compliance with DIN EN 590 may be used. Such
fuel may also be used in engines which have not been approved for operation with FAME, without
affecting oil drain intervals.
It is intended that future engine series will be approved for operation with 100% FAME. Further
details will be published at the appropriate time.
Fuel
• The fuel must comply with DIN EN 14214. Operation with fuels of lower quality can
lead to damage and malfunctions.
• Either FAME or diesel fuel may be used. The various mixtures of FAME and normal diesel fuel
which may occur in the fuel tank as a result, present no problems.
Engine Oil and Servicing
• For operation using 100% FAME, engine oils are to be preferred which comply with MB Fluids and
Lubricants Specifications, Sheet 228.5 or Oil Category 3 in accordance with MTU Fluids and Lubricants
Specifications. Engine oils in accordance with Sheet 228.3 or Oil Category 2 as per MTU Fluids and
Lubricants Specifications may also be used p rovided that oil drain intervals are reduced.
• A certain amount of fuel always finds its way into the engine oil via the pistons and cylinders. Its high boiling
point means that FAME does not evaporate but remains in the engine oil in its entirety. Under certain conditions
chemical reactions may take place between FAME and the engine oil. This can lead to engine damage.
• For this reason, engine oil and filter change intervals must be shortened for operation both
with pure FAME and with FAME-diesel mixtures.
