There are several cleaning methods for black engine oil: using alcohol, using olefins and turpentine, using special cleaning agents or detergents for gasoline, and using wind oil essence.

Use alcohol: alcohol can be dissolved in organic solvents, water and engine oil, and the best alcohol is anhydrous alcohol.
