Answer is: a mixture.

Crude oil is mixture (solution) consist of several different hydrocarbons (alkanes, alkenes...). This hydroalkanes can be separated from mixture (crude oil) using distilation (usually fractional distillation), because they have different boiling points.  

Proportion of hydrocarbons is diiferent in varios parts of the world.
