Engine oil dilution
Dilution of the engine oil can occur due to a small amount of fuel entering the crankcase during the post-injection phase. For this reason, calculations based on driving style have been introduced to reduce oil change service intervals if necessary. The driver is notified of the need to change the oil by a message on the instrument panel.
The DPF software monitors the driving style and the frequency and duration of active regeneration. With this information, calculations can be made about the dilution of the engine oil. When the DPF software calculates that engine oil dilution has reached a predetermined threshold (fuel is 7% of the volume of oil), a service message is displayed on the instrument panel.
Depending on your driving style, some vehicles may require an oil change before the scheduled interval. If a service message is displayed, the vehicle needs a full service, after which the service interval counter will be reset.
Fuel consumption
During the DPF active regeneration process, fuel consumption increases. However, since active regeneration occurs infrequently and for a limited period of time, the overall fuel consumption increases by approximately 2%. The extra fuel used during the active regeneration process is added to the instantaneous fuel consumption and the average fuel consumption is displayed on the instrument panel.
