Use of higher (10-20%) biodiesel proportions requires changes in the engine and its maintenance as
follows:
• You must change oil, oil filter and fuel filter elements twice as often than with less than 10% biodiesel
content.
• Engine must have an additional fuel pre-filter or water separator in the fuel line between the fuel tank
and the engine. The water separator requires frequent checks.
• The additional fuel pre-filter (inclusive water separator) must be specified and approved by AGCO
Power.
Use of higher biodiesel proportions are not allowed!
Consequences of use of fuels with 1st generation biodiesel blends
If you use biodiesel blends from 10% to 20%, you must consider the risks:
• Possible power and fuel economy reduction even up to 6%.
• Reduced fuel flow in cold environment.
• Possible fuel filters restriction and plugging.
• Possible fuel leakage through damaged seals and hoses.
• Possible coking of fuel injector nozzles.
• Possible engine oil dilution.
• Possible high acid levels within fuel system.
• Possible compatibility issues with other materials (including copper, lead, zinc, tin, brass and bronze)
used in fuel handling process.
• Reduction of service life on engine and exhaust system systems (SCR and cEGR).
• Increase of engine emissions that can lead engine to de-rate on SCR engines.
All the above mentioned risks are bigger with higher than 20% biodiesel blends. In addition higher
biodiesel blends cause other problems:
• Blockage of injector nozzles, resulting loss of power and engine malfunction.
• Crankcase oil soot formation, which results in shorter oil and oil filter lifetime.
• Corrosion of fuel injection equipments.
• Seizure of engine or internal components of the injection system.
2nd generation biodiesel
Use of the paraffinic diesel BTL/HVO (renewable diesel) according to the standard EN 15940 is permitted.
It can be used 100% in all AGCO POWER engine models. Fuel filtration and maintenance intervals remain
normal.
