Advice
If good-quality petrol with metal-free addi-
tiv
e
s
is not available or engine problems
arise, the necessary additives must be added
when refuelling ›››
.
Not
al
l
petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ›››

Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained.
CAUTION
●
Do not ref
uel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
●
Only use fuel with an octane rating that is
in line with the norm EN 228, otherwise sig-
nificant damage could be caused to the en-
gine and fuel system. Furthermore, it could
lead to a loss of performance with the conse-
quent engine fault.
●
The use of unsuitable petrol additives could
damage the engine.
●
If, in ex
ceptional circumstances, petrol with
a lower octane rating to that recommended is
used, only use moderate engine speeds and a
light throttle. Avoid using full throttle and
overloading the engine. Otherwise you may
damage the engine. Fill up with fuel of a suit-
able octane rating as soon as possible.
●
Just one full tank of leaded fuel would seri-
ously impair the efficiency of the catalytic
converter and could damage it.

uel must correspond to European
standard EN 590 (In Germany, EN 590 or
DIN 51628).
The use of diesel fuel with a high sulphur
percentage requires shorter service intervals

tell you which countries have diesel with a
high sulphur content.
Do not mix fuel additives (thinners, or similar
additives) with diesel fuel.
Winter-grade diesel
When using “summer-grade diesel fuel”, dif-
ficulties may be experienced at temperatures
below 0°C (+32°F) because the fuel thickens
due to wax separation. For this reason, “win-
ter-grade diesel fuel” is available in Germany,
for example, during the cold months. It can
be used at temperatures as low as -20°C
(-4°F).
In countries with different climatic condi-
tions, other types of diesel fuel are available
that are suitable to local temperatures. Tech-
nical service centres and filling stations in
the country concerned will inform you on the
types of diesel fuels available.
A cold diesel engine makes more noise dur-
ing winter temperatures than summer tem-
peratures. Furthermore, the exhaust gases
may turn slightly bluish while the engine is
heating. The quantity of exhaust gases will
depend on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a
fuel filter pre-heating system. This ensures
that the fuel system remains operational to
approx. -24°C (-11.2 ºF), provided you use
winter-grade diesel which is safe to -15°C
(+5.0°F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24°C (-11.2°F), simply place
the vehicle in a warm garage or workshop for
a while to heat up.
