Engine oil, or motor oil, is a lubricant for internal combustion engines, found in cars and even lawnmowers. The lubrication increases the efficiency of moving parts which move against each other. Lack of it increases fuel consumption and can lead to engine failure.
Rubbing of engine parts can lead to microscopic metallic parts deposited and circulated in the oil. Therefore an oil filter is often used to clean the oil.
