Volkswagen Touran Owners Manual: Petrol

First read and observe the introductory information and safety warnings 

Petrol types

Vehicles with a petrol engine must be run on unleaded petrol in compliance with the European standard EN 228  .

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.

Petrol additives

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  .

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  .

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.

NOTICE

• Use only fuel that complies with EN 228 and has the correct octane number. Otherwise, the engine and the fuel system could suffer severe damage. The engine could also lose power or fail.

• The use of unsuitable petrol additives can cause damage to the engine.

• If, in an emergency, you have to use petrol with an octane number lower than the recommended one, drive at medium engine speeds and avoid high engine loading. Risk of engine damage. Avoid high engine speeds and heavy engine loads. Otherwise, this may result in damage to the engine. Refuel with petrol with the correct octane number as soon as possible.

• Do not use fuels if they contain metal. This information is available at the filling station. LRP fuel (lead replacement petrol) also contains high concentrations of metal-based additives. Danger of damage to engine!

• Just one tankful of leaded fuel would seriously impair the efficiency of the catalytic converter and will also cause considerable damage to it.
