Question

Full synthetic oils are derived from crude oil or byproducts through a chemical process rather than the __________ process used for conventional oil.

• A. distilliation
• B. fractional distillation
• C. vacum distillation
• D. none of these

Answer 1

The correct option is A distilliation

Synthetic oil is a lubricant consisting of chemical compounds that are artificially made. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials. Full synthetic oils are derived from crude oil or byproducts through a chemical process rather than the distillation process used for conventional oil. The resulting synthetic oil has a more consistent molecular size and therefore tends to have somewhat more uniform properties.
