Type of petrol
The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with the standard
EN 228 and be sulphur-free. Fuels with a 10%
ethanol ratio can be refuelled (E10)
2)
. The types
of petrol are dierentiated by using the octane
numbers (RON) or via the anti-knock index
(AKI).
Super unleaded petrol 95 octane petrol or
normal 91 octane petrol at least
We recommend refuelling with super 95 octane
petrol (91 AKI). If not available, normal 91 oc-
tane petrol (87 AKI) (with a slight power loss)
may be used.
Super unleaded petrol, 95 octanes at least
You should use super 95 octane petrol (91 AKI)
at least.
If super petrol is not available, if necessary, use
normal 91 octane petrol (87 AKI). In this case
only use moderate engine speeds and a light
throttle. Refuel with super as soon as possible.
Unleaded super plus 98 octane petrol or su-
per 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super 95
octane petrol (91 AKI) (with a slight power loss).
If super petrol is not available, if necessary, use
normal 91 octane petrol (87 AKI). In this case
only use moderate engine speeds and a light
throttle. Refuel with super as soon as possible.
NOTICE
●
Fuels with a high percentage of ethanol,
e
.g. E30 - E100 button must not be used. The
fuel system would be damaged.
●
A single refuelling with leaded fuel or other
metal additives entails a permanent deterio-
ration of the eectiveness of the catalytic
converter.
●
Only use fuel additives that have been ap-
proved by SEAT. The products that contain
substances to increase the octane rating or
decrease knocking may contain metal addi-
tives that damage the engine and catalytic
converter. This type of products must not be
used.
●
Do not use fuels shown in the pump as
containing metals. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Risk of engine damage!
●
High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
Note
●
Fuel with an octane rating higher than the
one r
equired by the engine can be used.
●
In countries in which there is no sulphur-
free fuel, it is also allowed to use low sulphur
content fuel.
Ethanol fuel
✓ Valid for: vehicles with Totalflex engines
You can recognise vehicles with Totalflex en-
gines
3)
by label on the fuel tank lid with the
marking “Petrol/ethanol”.
Vehicles with Totalflex engine can run with un-
leaded petrol (95 octane / 91 AKI) according
to ANP No. 57 and with fuels with any high per-
centage of ethanol. The vehicle is refuelled in
the same way as petrol refuelling.
