Diesel (EN 590)

Fuel grade

G

WARNING

If you mix diesel fuel with petrol, the flash

point of this fuel mixture is lower than that of

pure diesel fuel. When the engine is running,

components in the exhaust system may over-

heat unnoticed. There is a risk of fire.

Never refuel with petrol. Never add petrol to

diesel fuel.

!

When refuelling, only use diesel fuel that

conforms to the European standard EN 590

or is of equivalent quality. Fuel that does

not conform to EN 590 can lead to

increased wear as well as damage to the

engine and exhaust system.

!

Do not use the following:

R

marine diesel

R

heating oil

R

bio-diesel

R

vegetable oil

R

petrol

R

paraffin

R

kerosene

Do not mix such fuels with diesel fuel and

do not use any special additives. This can

otherwise lead to engine damage.

!

Vehicles with a diesel particle filter: in

countries outside the EU, only refuel with

low-sulphur Euro diesel with a sulphur con-

tent under 50 ppm; otherwise the emission

control system could be damaged.

!

Vehicles without a diesel particle fil-

ter: in countries where only diesel fuel with

a high sulphur content is available, you will

need to carry out your vehicle's oil change

at shorter intervals. More information

about the interval for oil change can be

obtained from any qualified specialist

workshop.

Usually you will find information about the

fuel grade on the pump. If you cannot find the

label on the petrol pump, ask the filling sta-

tion staff.

Information on refuelling (Y page 159).

Low outside temperatures

In winter months, diesel fuel with an improved

cold flow quality is available. In Europe, the

EN 590 standard defines various climate-

dependent temperature categories. Malfunc-

tions can be avoided by refuelling with diesel

fuel that corresponds to the climatic specifi-

cations outlined in EN 590. At unusually low

outside temperatures, it is possible that the

flow characteristics of the diesel fuel could be

insufficient. Accordingly, diesel fuel from

warmer areas may not be suitable for opera-

tion in colder climatic conditions.

Further information on country-specific

fuel properties and fuel types with low-tem-

perature resistance can be obtained from

oil companies, e.g. at filling stations.

Fuel consumption information

Environmental note

CO

2

(carbon dioxide) is the gas which scien-

tists believe to be principally responsible for

global warming (the greenhouse effect). Your

vehicle's CO

2

emissions are directly related to

fuel consumption and therefore depend on:

R

efficient use of the fuel by the engine

R

driving style

R

other non-technical factors, such as envi-

ronmental influences, road conditions or

traffic flow

You can minimise your vehicle's CO

2

emis-

sions by driving carefully and having it serv-

iced regularly.

The vehicle will use more fuel than usual in

the following situations:

R

at very low outside temperatures

R

in urban traffic

R

on short journeys
