Fluid Leak Diagnosis - Ford Explorer 2020
A brown/black fluid leak, even if just a few drops, typically indicates engine oil or transmission fluid leakage. Given the color and consistency, it's likely engine oil from a worn gasket or seal, or possibly transmission fluid if it has a burnt smell. The leak is small but should be inspected promptly to prevent worsening.

Engine oil leak from valve cover gasket, oil pan gasket, or oil filter housing.
