Reset oil service/time and distance-dependent inspection/extra work


On vehicle with flexible service interval, the service intervals are calculated, in addition to driven distance and time, also using fuel consumption and oil temperature. This calculation gives a value of the oil's degradation in relation to thermal loading. On vehicles with diesel engines the oil's degradation is calculated based on engine rpm, engine load, driven distance, and oil temperature. This gives values for thermal loading and soot deposits. Oil degradation is the decisive factor for when the next service shall take place.

In some models from model year 2008 and later, not only values for oil change interval are indicated but also values for time and distance-dependent inspection (extra work), e.g., air filter, spark plugs, etc.
