How to find the engine oil maintenance point of an automobile engine

摘要

The invention relates to a method for determining engine oil servicing dates for a motor vehicle engine as a function of recorded engine operating parameters. According to the invention, the number of engine revolutions and at least one engine other operating parameter relevant to engine oil ageing are continuously recorded and, on the basis of this, a fictitious distance is determined by associating the recorded engine revolutions with the evaluation factors dependent on recorded engine operating parameter(s) relevant to engine oil ageing in accordance with a predeterminable association relationship. From this, a remaining operating distance until the next engine oil servicing date is then calculated by subtracting the determined fictitious distance from a specified total distance potential.
