Why don’t the higher density molecules of water descend in a bottle of wine? You don’t have the molecules of ethanol floating on top, do you?
(Hint: “higher-density molecules” doesn't mean anything.)
The oil and water have different densities, and are under the same force of gravity.
Any higher-density substance above a lower-density substance will have potential energy, that eventually must dissipate into thermal energy as the higher-density molecules descend and perturb other molecules.
