Vehicles with a catalytic converter in the exhaust system
Engine 55 kW. Unleaded gasoline, octane rating of at least 91.
Engines 66 and 110 kW. Unleaded gasoline, 95 octane or higher
Engines 85 kW. Unleaded gasoline, octane rating 95 or 91. The use of gasoline with an octane rating of 91 results in a slight loss of engine power.
Engine 128 kW. Unleaded gasoline, octane rating 95 or higher. When using unleaded gasoline with an octane rating of 98, the engine develops more torque at the same rated power.
Engine 135 kW. Unleaded gasoline, 98 octane.
The use of unleaded gasoline with an octane rating of at least 95 is allowed without restrictions. Correction of the ignition timing depending on the quality of the fuel (octane correction) is carried out automatically, however, under unfavorable operating conditions, this can lead to a slight loss of power. Partially the loss of power can be compensated by using gasoline with an octane rating of 98.
Vehicles without a catalyst
Carburetor engine 66 kW. Unleaded or leaded gasoline with an octane rating of at least 95.
Carburetor engine 85 kW. Unleaded or leaded gasoline, 95 or 91 octane. Use of 91 octane gasoline may result in a slight loss of power.
Directions:
- Unleaded fuel must comply with DIN 51 607 or DIN 51 600.
- If, for any reason, the tank is filled with fuel with an octane rating lower than that required by the engine, the engine should be run predominantly at medium speeds and with a light load.
- Under heavy load or high RPM, severe detonation can damage the engine. Refuel with the correct octane rating as soon as possible.
- Fuel with an octane rating higher than recommended can be used without restrictions, however, this does not provide any advantages in terms of engine power or fuel consumption.
- Vehicles with a catalytic converter should only be refueled with unleaded fuel.
- Even one refueling containing tetraethyl lead impairs the performance of the catalyst. In vehicles with an oxygen sensor, this also has an effect on the formation of a combustible mixture.
- To protect the environment and your own health, it is recommended that vehicles without a catalytic converter also use unleaded fuel whenever possible.
Additives
Driving performance, power and engine life are determined to a large extent by the quality of the fuel. The additives used are of particular importance (additives). Therefore, it is recommended to refuel only high-quality gasoline containing additives.
In case of fuel system malfunctions (for example, the engine does not start well, stalls at idle, or loses power) sometimes special additives that need to be mixed with gasoline help. These additives are designed to protect against corrosion, clean the fuel system and remove deposits (soot) from the engine.
Not all existing additives to gasoline have proven to be effective. At Volkswagen service stations, you can purchase additives that have passed factory tests and are recommended for use by car manufacturers, as well as information on their use.
