Fuel grade
Petrol engine
Never use fuel containing lead, otherwise
the catalytic converter will be perma-
nently damaged.
<
Ultra low sulphur petrol may also be used. Since
the engine has a knock control function, it can
run on different grades of fuel.
>
The engine of your BMW is rated to run on:
Super Plus/premium plus fuel, octane
number 98 RON.
Fill up with fuel of this grade whenever pos-
sible, so that the nominal performance and
fuel consumption values are achieved.
>
You can also run the engine on:
Premium-grade unleaded fuel, octane
number 95 RON.
This fuel is also sold under the following
designations:
DIN EN 228 or Eurosuper.
>
The minimum permissible grade is:
Regular-grade unleaded fuel, octane
number 91 RON.
If this grade of fuel is being used, the engine
may tend to make a knocking sound while
being started at high ambient tempera-
tures. This has no influence on the engine's
operating life.
National-market versions supplied
to run on leaded fuel*
With this specification, in addition to the grades
listed above, you can run the engine on leaded
fuel. The minimum grade is likewise 91 RON.
Diesel engine
Do not use rapeseed methyl ester RME,
biodiesel or petrol. If the wrong type of
fuel has been added, do not start the engine,
otherwise you risk causing damage to it.
<
Contact BMW Service if the wrong type of fuel
has been added.
>
Your BMW's engine is rated to run on:
Diesel oil to DIN EN 590 standard.
Winter-grade diesel oil
To ensure that the diesel engine operates relia-
bly during the cold season of the year, it must
be run on winter-grade diesel oil, which garages
usually sell during the period in question. Fuel
filter heating is installed as standard equipment
to prevent the fuel solidifying during operation.
Do not incorporate any additives, includ-
ing petrol, as these could cause damage
to the engine.
