This is not a well defined question because there are many different types of oils (motor oil, cooking oil, mineral oil, etc.) and the answer will depend on what type you're talking about.

Start with Wikipedia:
Wikipedia said:
Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils enhanced with additives, particularly antiwear additive plus detergents, dispersants and, for multi-grade oils viscosity index improvers. In addition to that, almost all lubricating oils contain corrosion (GB: rust) and oxidation inhibitors.
Wikipedia said:
Motor oils today are blended using base oils composed of petroleum-based hydrocarbons, that means organic compounds consisting of carbon and hydrogen, or polyalphaolefins (PAO) or their mixtures in various proportions, sometimes with up to 20% by weight of esters for better dissolution of additives.
Does that sound like a pure substance or a mixture?

Blend, or a solution. "Mixture"? Maybe. Motor oil is not just one compound collected as a liquid mass. MORE than one single compound collected as a liquid mass.
