Oil and water are often separated by density--the oil floats to the top and the water is drained from the bottom.

Oil and water can be separated by temperature--Oil usually boils at a higher temperature. Also oil and water freeze at different temperatures. Oil might solidify and is easy to remove in clumps.

Oil can be separated from a surface by skimming. A rotating disk lifts up the oil and a blade skims it off the disk.

There are filters that pass only water, not oil, and others that work in the reverse.

A wick floating on the surface oil will burn off the oil.

Lots more ways.

(1) Leave the oil alone so that it breaks down by natural means. If there is no possibility of the oil polluting coastal regions or marine industries, the best method is to leave it to disperse by natural means. A combination of wind, sun, current, and wave action will rapidly disperse and evaporate most oils. Light oils will disperse more quickly than heavy oils.

The only quick way to do this is to let the water & oil mixture rest until the oil has separated from the water. Then, you would skim the water or oil out of the top layer. Another option would be to boil the mixture until the drinking water has evaporated, but that isn't a very wise option.
