• Lubrication
Due to their non-polarity, oils do not easily adhere to other substances. This makes oils useful as lubricants for various engineering purposes. Mineral oils are more suitable than biological oils, which degrade rapidly in most environmental conditions due to oxidation.
• Painting
Color pigments can be easily suspended in oil, making it suitable as a supporting medium for paints. The slow drying process and miscibility of oil facilitates a realistic style. This method has been used since the 13th century.
