Vehicles with a petrol engine must be run on unleaded petrol in compliance with the European standard EN 228 вЂ‰.
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 refuelled with petrol that has a higher octane number than the engine requires. This does not, however, provide any advantage as regards the fuel consumption or the engine output.
We recommend petrol with a low sulphur content or sulphur-free petrol for use with this engine. This reduces petrol consumption.
The quality of the petrol influences running behaviour, performance and service life of the engine. For this reason, refuel with quality petrol containing suitable petrol additives. These additives will help to prevent corrosion, keep the fuel system clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available, or if engine problems arise, the necessary petrol additives must be added to the petrol during refuelling вЂ‰.
Not all petrol additives are effective. The use of unsuitable petrol additives can cause considerable damage to the engine and can damage the catalytic converter as well. 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 вЂ‰.
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.
