Hydrophobic.
No, oil does not contain water. Oil and water are immiscible, meaning they do not mix together. Oil is a hydrophobic substance, which means it repels water.
Hydrophobic repels water.
Petroleum isn't a single product, but rather a range of substances. Many will float on water, but not all.
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).
One substance with a specific gravity less than water is oil. This is why oil tends to float on top of water.

Hydrophobic repels water.
water is charged positively on the oxgen end, and negativelyon the hydrogen end. Oil does not have a charge ( it's netrual), so the oil does not mix with the water. (EDIT by Dr.J.) - Close, but actually water is charged NEGATIVELY on the oxygen and POSITIVELY on the hydrogen. So, it is POLAR, and oil is not polar, so they don't "mix".

Oil leaves a film on the surface that repels water and air, the two things needed for rust.

No, the ionic end of soap dissolves in water, not oil. The ionic end of soap is hydrophilic, meaning it is attracted to water molecules. It is the nonpolar end of soap that dissolves in oil, as it is hydrophobic and repels water.
No, oil does not contain water. Oil is a hydrophobic substance, meaning it repels water. Water and oil are immiscible, which means they do not mix together. This is due to the difference in their molecular structures and polarities. Oil is made up of hydrocarbons, while water is a polar molecule composed of hydrogen and oxygen.
oil.
Oil is insoluble in water because it is a nonpolar substance, while water is a polar substance. This means that oil molecules do not mix or dissolve in water, leading to the separation of the two substances.
