substance.
● Observe current safety instructions and lo-
cal regulations concerning the handling of

pend on the vehicle's engine. You will find a

Petrol types
Vehicles with petrol engines must refuel us-
ing unleaded petrol according to European
›››
norm 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 high octane num-
ber than the one recommended for your en-
gine. However, this has no advantage in
terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sul-
phur content or sulphur-free petrol to reduce
fuel consumption for petrol engines.
Petrol additives
Further in-
The quality of the fuel influences the behav-
formation
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the

fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives 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 unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane

ratings .
SEAT recommends "genuine Volkswagen
Group Fuel Additives for petrol engines".
These additives can be bought at SEAT deal-
ers, 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
