It is a mixture.
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
Petroleum is a mixture of hydrocarbons, which are compounds made up of hydrogen and carbon atoms. It is not a pure substance because it consists of multiple types of molecules with different properties.
A heterogeneous mixture with one substance present and two phases present is a suspension. In a suspension, the particles of one substance are physically mixed in another substance but are not dissolved, resulting in two separate phases. Examples include sand in water or oil in water.
Water and oil can be naturally mixed together through a process called emulsification, where small droplets of one substance are dispersed throughout the other substance. This can happen when a substance called an emulsifier is present, which helps to stabilize the mixture and prevent the oil and water from separating.
To determine the mole fraction of a substance in a mixture, you divide the moles of the substance by the total moles of all substances in the mixture. This gives you a ratio that represents the proportion of that substance in the mixture.

No. It is a mixture.
Crude oil is a complex mixture of hydrocarbons, as well as small amounts of sulfur, nitrogen, and other elements. Therefore, it is considered a mixture rather than a pure substance.

An insoluble mixture is defined as a mixture of substances where one substance will not dissolve into the other. Oil and water is an example of an insoluble mixture.
