Diesel Fuel; Filling The Tank - Seat Leon Owner's Manual

Diesel Fuel

Please note the information on the inside of the fuel tank
flap.
We recommend the use of Diesel fuel which complies to European standard
EN 590. If diesel fuel which meets European standard EN 590 is not availa-
ble, the Cetane number (CZ) must, at minimum, be 51. If the engine is
equipped with a particulate filter, the sulphur content of the fuel must be
below 50 parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it is more difficult to start the
engine. For this reason petrol stations in some countries also offer winter
diesel with improved fluidity when cold.
CAUTION
● The vehicle is not designed for the use of biodiesel (FAME fuel). The fuel
system would be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called "thinners", petrol or similar ad-
ditives with diesel fuel.
● If poor-quality diesel fuel is used, it may be necessary to drain the fuel
filter more frequently than is specified in the Service Plan. We recommend
having this done by a specialised workshop. If water is allowed to collect in
the filter, this can cause engine performance problems.
