Checking and refilling levels
Natural gas: “CNG” means Compressed
Natural Gas.
Type of petrol
3 Valid for: vehicles with petrol engines
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
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled
(E10)1). The types of petrol are differentiated
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 oc-
tane petrol (91 AKI). If not available, normal 91
octane 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.
3If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 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 is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
CAUTION
Fuels high percentage of ethanol, e.g.
E30 - E100 button must not be used. The
fuel system would be damaged. Exception:
vehicles with Totalflex engine ›› page 326,
Ethanol fuel.
A single refuelling with leaded fuel or
other metal additives entails a permanent
deterioration of the effectiveness of the
catalytic converter.
Only use fuel additives that have been
approved by SEAT. The products that con-
tain substances to increase the octane rat-
ing or decrease knocking may contain met-
al additives 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 required by the engine can be used.
In countries in which there is no sulphur-
free fuel, it is also allowed to use low sul-
phur content fuel.
1) Follow the regulations of the country you are
driving in.
