Note when refuelling
When handling fuel, comply with
the safety regulations displayed by
garages and filling stations.<
When refuelling, insert the filler nozzle fully into
the filler neck. Avoid lifting the filler nozzle dur-
ing refuelling, otherwise
> the supply of fuel will be cut off prematurely
> fuel vapour and fumes will be fed back less
effectively
The fuel tank is full when the filler nozzle cuts
out for the first time.
Fuel tank capacity
If the remaining operating range is below
50 km, approx. 30 miles, it is imperative to
add fuel, otherwise the engine's functions are
not assured and damage may occur.<
Petrol engine
Approx. 63 litres, approx. 13.9 Imp. gal., includ-
ing a reserve of approx. 8 litres, approx. 1.8 Imp.
gal.
Diesel engine
Approx. 61 litres, approx. 13.4 Imp. gal., includ-
ing a reserve of approx. 6.5 litres, approx.
1.4 Imp. gal.
Fuel grade
Petrol engine
Never use fuel containing lead, as other-
wise the catalytic converter will be perma-
nently damaged.
Do not fill the tank with E85, i.e. fuel containing
85% ethanol, nor with flex fuel. Otherwise the
engine and fuel supply system will be dam-
aged.<
For optimal fuel economy, the petrol should be
sulphur-free or as low in sulphur content as
possible. Since the engine has a knock control
function, it can run on different grades of fuel.
> Super Plus/premium plus fuel, octane
number 98 RON.
Fill up with fuel of this grade so that the
nominal performance 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:
DINEN228 or Eurosuper.
> The minimum permissible grade is:
Regular-grade unleaded fuel, octane
number 91 RON.
335i: premium-grade unleaded fuel, octane
number 95 RON.
Do not fill the tank with any petrol below
the specified minimum grade. Otherwise
the engine could be damaged.<
National-market specification for
leaded fuel*
This specification enables you to run the car on
leaded petrol, in addition to the fuel grades
listed above. The minimum approved grade is
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.
The filler neck is designed for refuelling at
diesel pumps.<
Winter-grade diesel
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 from solidifying during oper-
ation.
