Fuel
Introduction
This chapter contains information on the followingsubjects:
⇒ Petrol
⇒ Natural gas
Different engines require different fuels. The factory-fitted sticker on the inside of the tank flap
indicates the fuel type that is required for your particular vehicle.
Volkswagen recommends using low-sulphur or sulphur-free fuels, to help reduce fuel consumption
and prevent damage to the engine.
If the engine is not running smoothly or begins to judder, this can indicate poor or inadequate fuel
quality, e.g. water in the fuel. If these symptoms appear, reduce the vehicle speed immediately and
drive to the nearest qualified workshop at medium engine speeds, avoiding high engine loading. If
these symptoms occur immediately after the vehicle has been refuelled, switch the engine off as
soon as it is safe to do so and seek expert assistance. This can help to prevent further damage.

than the engine requires. However, this does not provide any advantage in terms of fuel
consumption or engine output.
Volkswagen recommends using fuel with a low sulphur content or sulphur-free fuel for petrol
engines in order to achieve reduced fuel consumption.
Petrol additives
The quality of petrol influences the running properties, performance and service life of the engine.
This is why the vehicle should be refuelled with good quality petrol that has only non-metallic
additives pre-added by the petroleum industry. These petrol additives help to prevent corrosion,
keep the fuel system clean, and prevent the build-up of deposits in the engine.
If good quality petrol containing non-metallic additives is not available, or if engine problems arise,
the necessary petrol additives must be added to the petrol when refuelling ⇒.
Not all petrol additives are effective. The use of unsuitable petrol additives can cause considerable
damage to the engine and catalytic converter. Metallic additives should be avoided at all times.
Petrol additives on sale that are intended to improve knock resistance or increase the octane
number can also contain metallic additives ⇒.
Volkswagen recommends genuine Volkswagen or Audi fuel additives for petrol engines. These
additives and information on how to use them are available from your Volkswagen dealership.
Natural gas engines
Run the petrol tank empty every 6 months until the indicator lamp lights up. This is necessary to
maintain the required system function for petrol mode and fuel quality.
Natural gas
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Natural gas
Natural gas can be delivered in compressed or liquefied form.
Liquefied Natural Gas (LNGyf L V S U R G X F H G E \ U D S L G F R R O L Q J R I W K H Q D W X U D O J D V 7 K L V G H F U H D V H V W K H

natural gas engine may not be refilled directly with liquefied natural gas as the gas would expand
too much once in the tank in the vehicle.
Vehicles fitted with a natural gas engine may therefore only be refilled and driven using
compressed natural gas ⇒.
Natural gas quality and consumption
Natural gas is available in two grades: H-gas and L-gas.
H-gas has a higher calorific value and a lower nitrogen and carbon dioxide content. The higher the
calorific value of the natural gas the lower the levels of consumption.
The calorific value and the nitrogen or carbon dioxide values may, however, vary within one quality
group. For this reason, the vehicle consumption may vary when using natural gas of the same
quality.
\f

The vehicle engine management will automatically adapt to the different natural gas qualities. Both
natural gas qualities can therefore be mixed in the fuel tank. You do not need to empty the tank
before refuelling with a different grade.
Natural gas
The vehicle can run on natural gas. Further information is available from your local Volkswagen
dealership.
Safe handling of natural gas
If you can smell gas or think there may be a leak in the natural gas system ⇒:

Park the vehicle on a level and stable surface.
Depress and hold the brake pedal until the engine has stopped.
Apply the handbrake firmly Braking, stopping and parking.
Select the neutral position or move the selector lever to N Changing gear.
Stop the engine and remove the vehicle key from the ignition Starting and stopping the
engine.
Allow the engine to cool sufficiently.
Children and other people should be kept well away from the engine compartment.
Ensure that the vehicle cannot roll away unexpectedly.
Service fluids leaks are harmful to the environment. So you should regularly check the
ground underneath your vehicle. If there are spots of oil or other fluids on the ground, the vehicle
should be inspected by a qualified workshop. Any spilt service fluids must be disposed of properly.
Preparing the vehicle for working in the engine compartment
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
The following steps should always be carried out in the specified order before working in the
engine compartment ⇒:
There are rotating components in the engine compartment that can cause serious injury.

If possible, only use Volkswagen-approved engine oil ⇒. The engine oils listed are multigrade
high-lubricity oils.
Engine oils are constantly being developed and improved. A Volkswagen dealership is always kept
up to date on innovations. Volkswagen therefore recommends having engine oil changes done by a
Volkswagen dealership.
The quality of the engine oil is not only tailored to the requirements of engines and exhaust gas
treatment systems, but also to fuel quality. Due to the way in which a combustion engine works,
engine oil always comes into contact with combustion residues and fuel, which has a knock-on
effect on the ageing process of the oil.
The quality of fuels can vary greatly between individual markets and this must be taken into account
when selecting the correct engine oil.
The use of engine oils compliant with the VW 504 00 requires a fuel quality compliant with EN 228
(petrolyf R U I X H O R I D Q G H T X L Y D O H Q W T X D O L W \ Engine oils compliant with VW 504 00 are therefore
unsuitable for use in a large number of markets.
