What does a brown stain indicate about engine fluid?

A brown stain is indicative of oil leakage in a vehicle. Engine oil is typically a dark brown or black color, especially as it ages and is used. When oil leaks, it can leave a brown stain on driveways or parking surfaces, which is an important indicator for vehicle maintenance. Identifying oil leaks is crucial because they can lead to significant engine problems if not addressed promptly. Regular checks on engine oil levels and monitoring for any stains can help drivers maintain their vehicle's health and prevent serious issues down the line.
