An oil leak occurs when oil escapes from its intended container, such as a vehicle's engine or a storage tank. This can happen due to various reasons, including worn-out seals, damaged gaskets, or corrosion. Oil leaks can lead to environmental pollution and can also cause mechanical issues in machinery if not addressed promptly. Detecting an oil leak is important for maintaining equipment and preventing further damage. Signs of an oil leak may include dark puddles under vehicles or machinery, a drop in oil levels, or unusual engine noises. Regular maintenance and inspections can help identify and fix potential leaks before they become serious problems.
