Function of engine oil

The engine oil is crucial for maintaining the optimum function of an engine. Over time, the engine oil suffers wear, especially if the intervals for oil service are not observed or the vehicle is driven mainly on short trips.

This often leads to oil dilution due to unburned fuel. In diesel vehicles, unsuccessful regeneration of the diesel particulate filter can also lead to oil dilution, especially in vehicles with high mileage or older models. Therefore, regular oil changes are critical to maintaining engine performance and vehicle performance.
