When ordinary users use engine oil, they recognize and locate a brand and even the appearance and properties of the oil. They think that the oil of this brand has this color. If it becomes darker or lighter in the future, they will think it is fake oil. Because of this perception, many lubricating oil manufacturers have encountered complaints about color problems, and some customers have even returned batches of products just because of color problems. It would be best if the quality of a brand’s engine oil is constant, as well as the appearance color. However, in actual production, it is difficult to achieve constant quality for many years. The main reasons are:
(1) The source of base oil cannot be constant. Even if the base oil is purchased from a certain refinery on a constant basis, the color of the lubricating oil produced in different batches will change due to the crude oil used by the refinery from different sources and changes in processes. Therefore, due to the different sources of base oil and various changing factors, the color differences in different batches appear to be normal.
(2) The source of additives cannot be constant. Competition in the additive market is fierce, and the development of additives is also changing with each passing day. Of course, manufacturers will shop around and try to use additives with high technical levels and affordable prices, and will often continue to change and improve with their development. For this reason, engine oil may vary from batch to batch. There are differences in different colors.
Color does not indicate quality. On the contrary, if the production company simply wants to maintain the color of the oil and cuts corners on the premise that the raw materials have changed, or passes off inferior products, then the color of the oil is guaranteed, but the quality is not. Do you dare to use it?
