13 Sep Is it possible to add lubricating oil without changing the previous one?
Having a pure black lubricating oil decomposition agent is normal and there is no need forany changes. However, there is still a need to change once in a while! Supplement will not only make up for the inadequacy of the oil quantity, but it also makes up for the loss of the lubricating performance. Lubricating oil in use process, due to pollution, such as oxidation quality will be worse, at the same time there will be some consumption, reducing the number. Give full usage to its performance of lubricating oil, use after a period of time will still need to be replaced.
