Why Does Oil Turn Black in a Car?
Oil turns black in a car due to various reasons, including contamination, oxidation, and breakdown of the oil’s additives. When oil is contaminated with dirt, dust, and other debris, it can turn black. The contamination can come from various sources, including the air filter, PCV valve, and engine gaskets.
