1.4 Fuels and lubricants
1.4.1 Biodiesel
NOTE:
Also see Service Bulletin 04/2016
Fuel quality
Use RME or PMW in accordance with DIN EN 14214.
RME
Rapeseed methyl ester
PME
Plant oil methyl ester
NOTE:
Cold-pressed rapeseed oil is
not
approved for use with standard tractors and forage harvesters.
Only cold-pressed rapeseed oil fuel in accordance with DIN V 51605 is approved for Greentec tractors.
Instructions for use
• Biodiesel is suitable for winter temperatures down to approx. -10 °C.
• At temperatures below --10 °C, diesel fuel needs to be added to prevent flocculation of the biodiesel.
The ratio of the two must be approx. 50:50. Only diesel fuel may be used at temperatures below -16 °C.
• Biodiesel can be mixed in any proportion with diesel fuel.
• Engine performance is reduced by 10–15 percent.
• There is a slight change in fuel consumption.
• If the engine is not going to be run for some time (3 months or more), fill with diesel fuel to prevent the
injection components from seizing.
Maintenance intervals
• Oil and oil filter change intervals must be halved.
• If conventional diesel fuel has been used in the past, the fuel filter must be replaced after fuelling with
biodiesel a few times. Since biodiesel acts as a solvent, any diesel residue may block the fuel filter.
Special features of biodiesel
• Biodiesel is obtained from vegetable oil (mainly rapeseed oil) by means of a chemical process, where
the vegetable oil is mixed with methanol and converted to biodiesel using a catalyst.
• Biodiesel is virtually sulfur-free and therefore produces almost no sulfur dioxide during combustion.
Biodiesel is more easily biodegradable and has less of an effect on the ground and groundwater in the
event of accidental spills.
IMPORTANT:
In spite of the high environmental compatibility of biodiesel, accidental spills must always be reported.
1.4.2 Biodegradable hydraulic oil
Oil quality
Use biodegradable hydraulic oil of type HEES with a rapeseed oil and synthetic base of viscosity ISO VG 32
or ISO VG 46.
NOTE:
Polyglycol-based synthetic oils cannot be used.
Instructions for use
Biodegradable hydraulic oil is suitable for winter temperatures down to approx. -15 °C.
