Fuel grade
Use unleaded fuel

fuel, which may be of the ultra-low sulphur
type. Since the engines have a knock
control function, they can run on different
grades of fuel.

number 98 RON.
Fill up with fuel of this grade w henever
possible, so that the nominal performance
and fuel consumption values are achieved.
You can also run the engine on:
>
Premium-grade unleaded fuel octane
number 95 RON.
This fuel is also known as:
DIN EN 228 or Euro-Super.
The minimum permissible grade is:
