Petrol additives
The quality of the fuel has a decisive influence upon the running
behavior, performance and service life of the engine. The additives
which are mixed into the petrol are of particular significance. It is
therefore advisable only to use good q q u u a a l l i i t t y y p p e e t t r r o o l l c c o o n n t t a a i i n n i i n n g g

Properties of RME
• RME is chemically produced from vegetable oil (predominantly
rapeseed oil) in a process whereby the oil is mixed with methanol
and converted, via a catalyst, into RME.
• RME is almost totally sulfur free. The combustion of RME thus
emits practically no sulfur dioxide (SO
• Exhaust gas contains less
– carbon monoxide
– hydrocarbons
– particles (i.e. soot)
than with conventional diesel fuel.
All emission values are lower than legal requirements.
• RME fuel is biodegradable.
• Performance may be slightly lower.
• Fuel consumption may be slightly higher.
• RME can be used in temperatures down to approximately –10 °C.
• Diesel fuel must be added at ambient temperatures of less than
–10 °C to prevent deterioration to the biodiesel. The mixing ratio
of diesel to biodiesel must be approximately 50:50.
