What should you do if the engine oil looks dirty?

When engine oil appears dirty, changing the oil immediately is essential for maintaining the health of the engine. Dirty oil indicates contamination from soot, carbon, metal wear, or other impurities that can hinder its ability to lubricate and protect engine components effectively.

If the oil is not changed, these contaminants can lead to reduced oil viscosity, increased wear, and even engine damage over time. Clean oil is crucial for optimal engine function, as it helps to keep the engine running smoothly and efficiently.

Ignoring the condition of the oil or mixing it with new oil will not resolve the underlying problem and may exacerbate wear and tear on the engine. Allowing the engine to cool down does not address the issue and can lead to further complications. Therefore, changing the oil promptly when it appears dirty is the best course of action to ensure the engine's longevity and performance.
