Engine Oil Level Check Instructions

Model: Mercedes Classe S MK 3, W140 - Years 1991-1998
Part: Checks and maintenance

All engines are equipped with a dipstick that allows you to check the engine oil level. At the end of the dipstick, there is a level indicator between MIN (minimum) and MAX (maximum), and it is absolutely important that the level is always between these two limits, never below or above. To check the level, simply pull out the dipstick, clean the end, insert it back in fully, and pull it out to see how far it is stained with oil. It is preferable to perform this check when the engine is cold, as you can be sure that there is no oil circulating and that it has all settled in the oil pan; when the engine is hot, it is absolutely necessary to wait about 10-15 minutes to allow all circulating oil to flow into the pan. Between the minimum and maximum levels, there is approximately one quart of oil.
