Synthetic oil

Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials. The base material, however, is still overwhelmingly crude oil that is distilled and then modified physically and chemically. The actual synthesis process and composition of additives is generally a commercial trade secret and will vary among producers.^[1]

Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature.^[2] Aircraft jet engines, for example, require the use of synthetic oils, whereas aircraft piston engines do not.^[3] Synthetic oils are also used in metal stamping to provide environmental and other benefits when compared to conventional petroleum and animal-fat based products.^[4] These products are also referred to as "non-oil" or "oil free".

A polyalcanoate synthetic oil is widely used to lubricate pendulum clocks.
