Saturated hydrocarbons, such as paraffin wax, contain only single bonds between carbon atoms, making them relatively stable and less reactive. These compounds are primarily derived from crude oil, a naturally occurring mixture of thousands of different organic molecules.
Decoding Oil Chemical Formula Structure and Understanding Its Composition
Each fraction has a specific range of molecular weights and corresponding chemical formulas. For example, detergents are added to prevent engine sludge, while antioxidants are included to inhibit the degradation caused by heat and oxygen exposure.
Short-chain molecules are typically gases, while longer chains form the viscous liquids we recognize as fuels and lubricants, and the solid waxes used in candles and sealing compounds. These chains can range in length from just a few carbon atoms to several dozen, leading to a dramatic variation in their characteristics.

Fraction Typical Carbon Range Common Use Refinery Gas C1 - C4 Heating and cooking Gasoline C5 - C12 Vehicle fuel Kerosene C10 - C16 Jet fuel and lighting Diesel C10 - C20 Truck and marine engines Lubricating Oil C20 - C50+ Engine and machinery lubrication Additives and Functional Chemistry While the base stock defines the core properties, modern oils are sophisticated formulations that include a variety of chemical additives. For instance, gasoline consists of hydrocarbons with roughly 5 to 12 carbon atoms, while diesel fuel contains molecules with 10 to 20 carbon atoms, and heavy lubricating oils are composed of even larger, more complex structures.
