No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
Salad oil is not soluble in water. It is primarily composed of fats, which do not mix with water due to their nonpolar nature. Water is a polar solvent, and as a result, oil and water will separate when combined, with oil floating on top.
Oxygen combined with one other element is an oxide.
The element combined with aluminum in Al2O3 is oxygen.
Water is not an element, it is a compound composed of oxygen and hydrogen. The chemical formula for it is H2O. That is 2 hydrogens and 1 oxygen atoms combined.
In the android game Alchemy, the colors of the words represent the current status of combining elements. Light grey means the element cannot be combined further, red means the element cannot be combined with any other element, and black means the element can be combined with another element.
Water is not an element (H is an element, O is an element, when combined together it is not an element). See related question below.
Oil and water are both compounds, not elements.
water+coal=oil
Emulsions
No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
sodium, combined with chlorine, it makes salt, but in pure form, it explodes in water
the result is an emulsion.
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).
It is neither, it is an element

It is oil, and therefore does not mix well with water, but it can eventually be broken down when combined with water for a long period of time, and dissolve into the water.
