Petrol Types; Diesel - Seat Alhambra Owner's Manual

Petrol types

The correct petrol types are listed on a sticker inside the fuel
tank flap.
Only unleaded petrol, corresponding to the standard DIN EN 228, may be
used for vehicles with catalytic converters (EN = "European Norm").
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= "Regulation Octane Number, unit for determining the knock resistance of
petrol"). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power. If, in exceptional circumstances, the correct
octane rating is not available:
•
For engines which require Premium unleaded petrol (95 RON) the
following is valid: Regular unleaded fuel with 91 RON can also be used. This
can, however, result in a slight loss of power under certain driving conditions.
•
For engines which require Premium unleaded petrol (98 RON) the
following is valid: Premium unleaded fuel with 95 RON can also be used. This
can, however, result in a slight loss of power under certain driving conditions.
– If premium unleaded petrol is not available, the engine can be run on
regular unleaded petrol with 91 RON as an "emergency measure". In this
case only use moderate engine speeds and a light throttle. Avoid using full
throttle. Fill up with premium petrol as soon as possible.
Caution
•
Petrol that follows EN 228 may be mixed with small quantities of ethanol.
However, the so-called "bioethanol fuels" available at commercial establish-
ments with reference E50 or E85, which contain a high percentage of ethanol,
may not be used, as they will damage the fuel system.
•
Even one tankfull of leaded fuel would permanently impair the efficiency
of the catalytic converter.
Safety First Operating instructions
•
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.
For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.

Diesel

Diesel*
Diesel fuel must correspond to DIN EN 590 (EN = "European standard"). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒ page 206.
RME fuel*
Only vehicles fitted with special equipment may drive with
biodiesel fuel in accordance with standard DIN EN 14214.
The biodiesel fuel must comply with the DIN EN 14.214 (FAME) Standard.
•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is a German abbreviation for "Deutsches Institut für Normung e.V.",
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation "Fatty Acid Methyl Ester"
