These molecules are "saturated" with hydrogen atoms, making them very stable and clean-burning. Olefins, such as ethylene and propylene, feature double or triple bonds between carbon atoms, making them highly reactive.
Nitrogen Oxygen Compounds in Crude Oil Composition
Similarly, vast forests contributed plant matter that was swept into swamps. This mixture of organic material, primarily lipids and proteins, formed the initial kerogen, a waxy substance that is the precursor to fossil fuels.
Pressure, Heat, and Transformation Buried under thousands of feet of sediment, the kerogen was subjected to immense pressure and rising temperatures. Decoding the Hydrocarbon Mixture While often described as a simple fuel, what oil is made of is actually a sophisticated cocktail of hydrocarbons.
Nitrogen Oxygen Compounds in Crude Oil Composition
Impurities and Trace Elements Beyond the hydrocarbons, the composition of oil is not purely carbon and hydrogen. Crude oil contains various impurities that are separated during the refining process.

Looking at What is oil made of from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on What is oil made of can make the topic easier to follow by connecting earlier points with a few simple takeaways.
