it is a mixture
Crude oil is a mixture of short to long chain hydrocarbons. It has to be separated into many different fractions to become usable. It may also contain mineral impurities due to it being underground
It is a mixture of hydrocarbons, which can be separated by fractional distillation. Oil is NOT an element.
Crude oil contains a mixture of hydrocarbons molecules
because crude oil is made out of two differents elements

gasoline is from crude oil so it's not a pure substance
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).
