Volkswagen Touran Owners Manual: Engine oil consumption

First read and observe the introductory information and safety warnings 

Engine oil consumption will be different from engine to engine and can change during the working life of an engine.

Depending on how you drive and the conditions in which the car is used, oil consumption can be up to 1.0 litre/2,000 km – and is likely to be higher for the first 5,000 km for new vehicles. For this reason the engine oil level must be checked at regular intervals, preferably when filling the tank and before a long journey.

When the engine is working hard the oil level must be kept within area  , for instance during long motorway cruising in summer, trailer towing or climbing on mountain passes.
