What is synthetic oil?

Explanation:
Synthetic oil is a lubricating oil created by chemically modifying the base stock to achieve specific performance characteristics, such as enhanced high-temperature stability, oxidation resistance, and shear stability. This engineered oil is well suited for turbine engines because they operate under demanding, high-heat conditions, and synthetic oils can provide reliable lubrication and longer service life than standard mineral oils. It isn’t simply fossil-based oil with no additives, and it isn’t limited to automotive use. Also, no oil has a truly fixed viscosity across all temperatures; synthetic oils are designed to maintain more stable viscosity over temperature, though viscosity still changes with temperature. So the best description is that synthetic oil is a lubricating oil made by chemically changing the base to provide the needed characteristics, and it is commonly used as the primary oil for turbine engines.
