Engine oil starts as an amber color and gets progressively darker as it runs through your vehicle. It's time for an oil change if it gets to the point of being dark brown or black.

These darker colors are due to sludge buildup, and oil sludge can cause severe damage to other components if it continues to travel through your engine. You may also notice a change in the oil's viscosity or its resistance to flow. If your oil is sludgy and drops in blobs from the dipstick, it is too thick.
