Volkswagen Golf Owners Manual: Petrol

First read and observe the introductory information and safety warnings

Petrol types

Fuels with a maximum ethanol content of 10% (E10) can be used for refuelling.

Petrol types are categorised according to their octane number, e.g. 91, 95, 98 or 99 RON (RON = Research Octane Number). The vehicle may be filled with petrol that has a higher octane number 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 mixed with 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.
