Synthetic diesels
Synthetic diesels.
XTL fuels are diesel fuels that are manufactured synthetically. These synthetic diesel fuels includeGTL
(Gas To Liquid), BTL (Biomass To Liquid) and HVO (Hydrotreated Vegetable Oils), where natural gas or biomass are
used as the initial energy carrier.
Fuel standard
—EN 15940.
—DIN EN 15940.
NOTICE
Using fuel that does not comply with these standards and is not approved may reduce performance and cause
damage to the engine and fuel system.
● Before refuelling, check whether the fuel identification specified on the pump meets the vehicle's requirements.
● Use only fuels that meet the required standards and labelling in order to prevent damage to the fuel system and
engine failure.
Petrol
The petrol types differ in their research octane number(RON). The vehicle may be filled with petrol that has a higher
RON than the engine requires. However, this does not provide any advantage in terms of fuel consumption or engine
output.
The fuel information label on the inside of the tank flap may show several types of petrol, e.g9. 5/92/97/93 RON. The
highlighted petrol grades, 95/92 in the example, are the preferred petrol grades for the vehicle. The other listed
petrol grades may only be filled if the highlighted ones are not available. In this case, choose the petrol grade with
the higher RON, e.g. 97 instead of 93 RON.
Fill vehicles with a petrol engine only with unleaded petrol or petrol with a maximum ethanol content of 10 %(E10)

The fuel quality affects the running properties, performance and service life of the engine. Refuel with fuel that
already contains suitable additives →

NOTICE
Errors during refuelling or unsuitable fuel additives may cause damage to the vehicle.
● Before refuelling, check whether the fuel standard specified on the pump meets the vehicle's requirements.
● Use only service additives that have been approved by Volkswagen Commercial Vehicles in the approved quantity.
● Refuel only with petrol that has the specified or a higher Research Octane Number(RON). If, in an emergency, you
have to use petrol with an octane number lower than the recommended number, drive at medium engine speeds
and avoid high engine loading. Avoid high engine speeds and heavy engine loads. Refuel with petrol with the
correct octane number as soon as possible.
