What is a characteristic of straight mineral oil?

• A. It is the lubricating oil obtained by fractional distillation of crude oil with no additives.
• B. It contains ash-forming additives.
• C. It is synthetic oil.
• D. It is designed for automotive engines.

Answer: (A)

Straight mineral oil is defined by being the lubricating oil obtained directly from crude oil by fractional distillation and used without any additives. This means it is the base oil with no ash-forming detergents, anti-wear agents, or other additives that formulated lubes contain. It is not a synthetic oil, since synthetic products are chemically engineered rather than simply distillate-derived base oils. And while oils for automotive engines are typically formulated with additives, straight mineral oil by itself isn’t characterized as specifically designed for automotive engines.
