WARNING
Refuelling or handling fuel carelessly can cause an explosion or fire
resulting in serious burns and injuries.
Fuel is a highly explosive, easily flammable substance.
Observe current safety instructions and local regulations concerning
the handling of fuel.
Types of fuel
The type of fuel to use when refilling will depend on the vehicle's engine. You
will find a factory-fitted sticker containing information on the type of fuel for
your vehicle on the inside of the fuel tank flap.
SEAT recommends the use of sulphur-free or low sulphur fuel to reduce
consumption and prevent engine damage.

Petrol types
Vehicles with petrol engines must refuel using unleaded petrol according to
European standard EN 228 .
Petrol types are categorised according to their octane number (e.g. 91, 95, 98
or 99 RON (RON = "Research Octane Number"). You may use petrol with a
higher octane number than the one recommended for your engine. However,
this has no advantage in terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sulphur content or sulphur-free petrol
to reduce petrol consumption for petrol engines.
Petrol additives
The quality of the fuel influences running behaviour, performance and service
life of the engine. For this reason, you should use good quality petrol
containing a mixture of additives. These additives will help to prevent corro-
sion, keep the fuel system clean and prevent deposits from building up in the
engine.
If good quality petrol with 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 unsuit-
able petrol additives could damage the engine. These additives are available
from qualified workshops, who will inform you of their application.
Caution
Only use fuel with an octane rating that is in line with the norm EN 228,
otherwise significant damage could be caused to the engine and fuel system.
Furthermore, it could lead to a loss of performance with the consequent
engine failure.
The use of unsuitable petrol additives could damage the engine.
