Fuel
Types of petrol
The correct grade of petrol is listed inside the fuel tank flap.
The vehicle is equipped with a catalytic converter and must only be run on
unleaded petrol. The petrol must comply with European Standard EN 228 or
German standard DIN 51626-1 and must be unleaded. You can refuel with a
maximum ethanol proportion of 10 % (E10). The types of petrol are differen-
tiated by their octane rating (RON).
The following titles appear on the corresponding adhesive on the fuel tank
flap:
Super unleaded 95 octane or normal 91 octane unleaded petrol
We recommend you use super 95 octane petrol. If this is not available: nor-
mal 91 octane petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95 octanes
You should use super petrol with a minimum of 95 octanes.
If super is not available, in an emergency you may refuel with normal 91 oc-
tane petrol. In this case only use moderate engine speeds and a light throt-
tle. Refuel with super as soon as possible.
Super unleaded 98 octane or super 95 octane unleaded petrol
We recommend you use super plus 98 octane petrol. If this is not available:
super 95 octane petrol, with a slight decrease in power.
If super is not available, in an emergency you may refuel with normal 91 oc-
tane petrol. In this case only use moderate engine speeds and a light throt-
tle. Refuel with super as soon as possible.
Petrol additives
The quality of the fuel influences the behaviour, performance and service
life of the engine. This is why the petrol you use should carry suitable addi-
tives already included by the petrol industry, free of metals. These additives
will help to prevent corrosion, keep the fuel system clean and prevent de-
posits from building up in the engine.
If good quality petrol with metal-free additives is not available or engine
problems arise, the necessary additives must be added when refuelling
⇒
.
Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives may cause significant damage to the engine and the
catalytic converter. Metal additives should never be used. Metal additives
may also be contained in petrol additives for improving anti-detonation rat-
ings or octane ratings ⇒
.
SEAT recommends “Genuine Volkswagen Group fuel additives for petrol en-
gines”. These additives can be bought at SEAT Authorised Services, where
information on how to use them can also be obtained.
CAUTION
● Do not refuel 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!
● Never refuel with fuels containing a large proportion of ethanol (for ex-
ample, E50, E85). This could damage the fuel system.
● Just filling one full tank of leaded fuel or fuel containing other metal ad-
ditives would seriously impair the efficiency of the catalytic converter.
