You're talking about super black armor, all made in synthetic engine oil, and its performance is similar to that of domestic licensed Castrol guard bars. Super black armor is made in the United States, and all the domestic products are smuggled parallel imports. So there is no Chinese on the bottle, and the volume doesn't matter how much it rises. On the other hand, 1 quarto is about 0.946 liters. The performance of this oil is still very good, but be careful not to buy fakes or futures. That friend doesn't know what Heijia is at all, so he dares to say that he is not as good as the yellow shell. This kind of person is too irresponsible to talk, and doing things is being a man. Dare to say "feeling is not as good as", answer questions accurately, and knowledge theory can't make you feel and imagine. Black armor 0w40 is fully synthetic, how can it be worse than yellow shell? Even the blue shell is inferior to it! Even the gray shell is at best tied with it.
