What are common contaminants found in engine oil?

Engine oil is crucial for maintaining the performance and longevity of an engine, and it can become contaminated by various substances during operation. Dirt and carbon are common contaminants found in engine oil. Dirt can enter the engine through various pathways, such as during air intake or from the environment. Once inside, this dirt can mix with oil and cause wear on engine components.

Carbon, on the other hand, often originates from the combustion process. Fuel combustion can produce carbon deposits that can make their way into the engine oil. These contaminants can lead to reduced lubricating properties of the oil, increased wear on engine parts, and potentially cause engine malfunctions.

Recognizing these specific contaminants is vital for developing maintenance practices, such as regular oil changes and the use of filters, to ensure the engine runs efficiently and is protected from damage caused by buildup over time.
