The
use of leaded petrol is very detrimental
to the functioning of the emission control
system
because the lead is deposited in the
catalytic converter.

Although unleaded fuel may again be used
afterwards the original efficiency of the
catalytic converter is never fully attained.
On
vehicles
with

Notes

• Unleaded petrol must comply
with
DIN3' 51 607 and leaded petrol
with
DIN 51 600.
• Only good quality petrol containing addi tives should be used - see also" Petrol addi

tives"
next column.
• If in an emergency the octane rating of the available petrol is lower than
that
required by the engine, only drive
with
me
dium engine speeds and low engine load
ing.
High
engine
loading
with
full

throttle
or
high
revs
can cause en
gine
damage.
Fill tank
with
petrol of the
correct rating as soon as possible.

Petrol
additives

The
quality of the fuel has a decisive influ
ence
upon the running behaviour, perform

ance
and service life of the engine. The addi
tives which are mixed into the petrol are of particular significance. One is advised
therefore only to use good
quality
pet
rol
containing
additives.

If such fuel is not available, or if engine
troubles such as starting difficulties, stalling during idling, vibration and loss of power
occur,
the appropriate additives should be
mixed
with
the petrol when filling the tank.
At temperatures between about 0 and 15
degrees
C, these additives prevent possible icing up of the carburettor, have an anti-cor
rosion effect, clean the fuel system and pre
vent deposits building up in the engine.

Petrol
additives available in accessory
outlets have not all shown themselves to be
effective. Therefore additives which have

been
tested for
Volkswagen
engines are av

ailable
from Volkswagen dealers in
Ger
many and in many export countries. The

Volkswagen
dealers are also informed
with
regard to the use of additives, and they know what to do in
cases
where deposits

have
already built up.
