Water and oil do not combine because water molecules are polar in nature, while oil molecules are non-polar. Oil also floats on water, because oil molecules have a lower density than water molecules.
Polarity means that one end of a given molecule is positively charged, while the other end is negatively charged. Polar solvents such as water will only successfully dissolve other polar molecules, which excludes oil molecules.
