Engine oil
Vehicles with a diesel particle filter:
If the vehicle is mostly driven for short distances, it is possible that malfunctions may occur during the automatic cleaning of the diesel particle filter. This can lead to engine damage. Therefore, if you frequently drive short distances, make sure to drive on highways or inter-urban roads for 20 minutes at least every 310 miles (500 km).
