Is it true that Baishun maintains gray shell engine oil?

It's true. Baishun auto oil, if it is in the formal channel, the regular manufacturer has his qualified mark, preferably a big dealer, and the big auto parts city has channels with anti-counterfeiting marks. It is really possible that it is normal and can be used with confidence. If it is bought through real shady channels or many repair shops with bad reputation, it may not be true. This kind of fake is widespread in society, so we should pay attention to identification.
