Identication of fuels

Fig.202 Identication of fuels according to
European Union (EU) Directive 2014/94/EU
Fuels are identied by dierent symbols on
the pump and on your vehicle's tank ap.
This identication avoids confusion when se-
lecting the fuel
Means petrol with a maximum of 5%
Ethanol.
Means petrol with a maximum of 10%
Ethanol.
Means petrol with a maximum of 20%
Ethanol.
Diesel according to EN590 standard. The
number indicates the maximum percent-
age of Biodiesel in the fuel. “B7” means a
maximum of 7% Biodiesel.
Synthetic diesel according to EN15940
standard.
Natural gas: “CNG” means Compressed
Natural Gas
Type of petrol
The correct grade of petrol is listed inside the
fuel tank ap.
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. Follow the regu-
lations of the country you are driving in. 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 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.
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 deteri-
oration 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
