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.
