Oil is nonpolar hydrocarbons. They don't mix in water or polar substances. However, they mix in other nonpolar substances like oils and fats and ethyl chloride.

Oil can refer to vegetable cooking oil. Examples are corn oil and coconut oil.

Oil can refer to petroleum, a type of black oil which can be fractionally distilled into tar, asphalt, gasoline, propane, butane, and more. Also the United States gets their oil from other countries by buying it, seizing it, or going to war for it.

Oil is also slang for synthol and the idiots who inject synthol and it doesn't increase strength, it only makes you have fake looking muscles. They then lift small to medium weights and still can't handle it or they lift fake weights. These people are called oilers. They don't do real weight lifting.
Chemist: This oil and water don't mix. Oil is nonpolar while water is polar. This oil mixes in ethyl chloride. They're both nonpolar.

Chef: I am going to use corn oil to cook my food.

United States: Iraq has oil? Time to seize the oil!

Oilers: Time to inject synthol! This is good oil.

People: Ha ha! Those muscles look fake!

Get the Oil mug.
A hydrocarbon-based, flammable, highly-polluting liquid formed as a result of millions of years of decaying sediment composed of dead microscopic animals. This fossil fuel is the lifeblood of our Industrial civilization, and for as long as it can be cheaply extracted, we are hopelessly dependent upon it for transportation, agriculture, electricity, fashion, chemicals, fertilizers, cosmetics, plastics, medical, and technological needs.

Unfortunately for us, the geologists, analysts, mathematicians, and former oil-company employees have all repeatedly come up with proof that our oil supply will be almost gone by the end of the 21st century, and that oil production will peak within a few years from now, if it hasn't already sone so.
After it peaks the oil will then become more expensive to extract than to use. And immediately after that, prices will soar, businesses will shut down, people will panic like animals, economies will collapse, wars will break out, blood will soak the ground, and billions of people will die horrible deaths as our species shrinks back to the population of the 1700s, or even that of Medieval times.

All because of that cursed, smelly brown muck that was once found oozing from the round.
Our religious belief that our oil supply is infinite will be the death of billions of us when Nature eventually forces us to see how wrong we are. Too bad we STILL haven't advanced our alternative fuel sources to prepare for that inevitable day when the last drop of cheap oil can be extracted.
