and safety warnings
The engine oil must be changed regularly in accordance with the data given in the service schedule.
The engine oil and filter change should always be carried out by a qualified workshop due to the special tools and knowledge required. This also applies to the disposal of used oil. Volkswagen recommends using a Volkswagen dealership for this purpose.
More details on the service intervals can be found in the service schedule.
Additives in the engine oil can cause new engine oil to discolour quickly. This is normal and does not mean that the engine oil should be changed more frequently.

WARNING
Before changing the engine oil, first find out where old oil can be disposed of properly near you.
Used oil must be disposed of in accordance with regulations governing the protection of the environment. Never dispose of old oil in locations such as gardens, woods, sewerage systems, on streets and roads, or in rivers and waterways.
