Well,to change your oil,You have to first drain the old oil from the oil pan it is located under you engine, The oilpan will then release the old oil from your car.Wait until the remaining oil are emptied.When the drops are gone close the bottom oil pan before putting new oil these will help to prevent oil spillage.The container depend on the model of engine,but usually its located near the cylinder head,the upper part of the engine.Make sure also that your
Mercedes Benz oil filter is still in good quality when you will change your oil.I hope my advise can help you.
