What You'll Learn
Gasoline is derived from the words 'gas' and chemical suffixes '-ole' and '-ine'
The term 'gas' in the context of car fuel is derived from the word 'gasoline'. Gasoline, according to English dictionaries, originates from the word 'gas' combined with the chemical suffixes '-ole' and '-ine'. The term 'gasoline' itself was derived from a brand name, much like how the brand name 'Scotch' is often used to refer to cellophane tape.
The use of the term 'gas' for car fuel is predominantly an Americanism, with most other countries using the term 'petrol', derived from the Medieval Latin word 'petroleum', which comes from 'petra' (rock) and 'oleum' (oil).
The early fuel companies competed to showcase their products, and one company advertised its fuel as being a 'gas', implying that it was lighter and would thus allow for greater vehicle speed. This was a false claim, but it caught on in the United States, where short, catchy slogans were popular. The term 'gas' was also used as it is shorter and catchier than 'petrol' or 'gasoline'.
The term 'gas' in reference to car fuel is unrelated to the state of matter of the substance, as it is a liquid. The use of the word 'gas' in this context is an example of 'forward-looking grammar', a linguistic technique where matter is described in its future state.

Gasoline is a mixture of hydrocarbons
The term 'gas' in the context of car fuel, is derived from the word gasoline. Gasoline is a mixture of various hydrocarbon compounds with heavier molecular weights than propane. Hydrocarbons are organic compounds consisting of hydrogen and carbon atoms, and they are the primary constituents of crude oil and natural gas. The Shukhov cracking process, introduced in 1891, was the first commercial method to break down these heavier hydrocarbons into lighter products, marking a significant step towards the development of modern gasoline.
Commercial gasoline, or car fuel, is a complex mixture of hydrocarbons produced in oil refineries. Approximately 72 liters of gasoline can be derived from a 160-liter barrel of crude oil through distillation. This process separates the different components of crude oil, and the resulting material, known as virgin or straight-run gasoline, does not meet the specifications for contemporary engines. Thus, it undergoes further refinement to enhance its performance characteristics.
The composition of gasoline varies with the season, requiring less volatile blends during the summer to minimize evaporative losses. Additionally, substances are often added to improve combustion, prevent corrosion, and enhance overall performance. For instance, ethanol is sometimes added to gasoline to improve combustion, but it is more susceptible to absorbing atmospheric moisture, which can lead to the formation of gums and solids that hinder engine performance.
To ensure optimal engine performance and prevent issues like "stale fuel," gasoline should be stored correctly. This includes using airtight containers to prevent oxidation and water vapor mixing, maintaining stable cool temperatures, and considering the vapor pressure capabilities of the container to prevent the loss of volatile fractions. Proper storage conditions help prevent the formation of gums and solids, which can corrode system components and impair engine functionality.

Gasoline is stored in airtight containers to prevent oxidation
The term 'gas' in the context of car fuel, originates from the word ''gasoline', which comes from 'gas' plus the chemical suffixes '-ole' and '-ine'. Gasoline is a highly flammable liquid and vapour that, when ignited, powers the internal combustion engines of cars.
Now, gasoline must be stored in airtight containers to prevent oxidation and evaporation, which can alter its combustibility. Oxidation occurs when oxygen, heat, and humidity come into contact with gasoline. This process can cause the fuel to degrade and form gum and solid residues that can corrode engine components and accumulate on wet surfaces. This condition is known as 'stale fuel'.
To prevent oxidation, gasoline should be stored in airtight, approved containers that can withstand vapour pressure without venting. These containers are designed to prevent the loss of volatile fractions and reduce the risk of dangerous pressure build-up. They also ensure the safe storage of gasoline, preventing spills and leaks. It is crucial to keep these containers tightly sealed, stored upright, and away from direct sunlight and heat sources.
Additionally, gasoline should be stored in a detached garage or shed, at least 50 feet away from ignition sources. It is not recommended to store gasoline in vehicles, and any spills or leaks should be properly cleaned and disposed of to prevent fires or environmental contamination. Proper storage can help maintain the quality of gasoline for up to six months.
Overall, storing gasoline in airtight containers is essential to prevent oxidation, maintain fuel quality, and ensure safe handling and storage.

Gasoline contains additives to improve combustion and engine performance
The term 'gas' in the context of car fuel, comes from the word gasoline, which is derived from 'gas' plus the chemical suffixes '-ole' and '-ine'. Gasoline is a mixture of over 150 hydrocarbons, including paraffins, olefins, and aromatics.
To meet modern performance, environmental, and safety standards, refiners, distributors, and consumers often mix various chemicals and additives into gasoline. These additives are blended with gasoline to improve engine performance, enhance fuel combustion, and meet environmental standards.
Some additives are aimed at improving engine performance, such as antiknock agents, which reduce engine knocking for smoother performance. Cetane and octane boosters improve the combustion quality of gasoline, allowing fuel to burn more efficiently and reducing the risk of engine knocking. Detergent additives help maintain engine cleanliness by reducing carbon deposits on fuel injectors and intake valves, ensuring efficient vehicle performance and reduced emissions. Lubricity additives improve the lubrication of moving parts, reducing wear and prolonging engine life.
Other additives help fight corrosion and engine wear, such as metal deactivators, which neutralise the catalytic effect of trace metals that accelerate fuel degradation. Corrosion inhibitors, like amines or phosphates, protect fuel systems from rust and corrosion. Antioxidants, such as phenylenediamines and phenols, slow oxidation that can form gums and varnishes.
In addition to conventional fuel additives, unconventional additives such as isopropyl ether, aniline, diethylamine, dimethyl malonate, and p-tert-butylphenol have shown potential in improving fuel combustion and engine performance.

Gasoline is produced in oil refineries
The term gasoline is derived from the combination of the word "gas" and the chemical suffixes "-ole" and "-ine". It is a complex mixture of hydrocarbons, produced in oil refineries from crude oil.
In oil refineries, crude oil is heated in a furnace until it vaporizes into a gas. The liquids and vapours then enter an atmospheric distillation tower, where they are separated into different streams or fractions based on their boiling points. This process, known as distillation, results in the separation of material from crude oil, called virgin or straight-run gasoline. However, this material does not meet the specifications for modern engines. To create gasoline that does, refinery technicians carefully combine a variety of streams from the processing units, taking into account octane level, vapour pressure ratings, and other factors.
The performance specifications of gasoline vary with the season, requiring less volatile blends during the summer to minimize evaporative losses. Additionally, other substances are often added to improve chemical stability and performance, control corrosion, and provide fuel system cleaning. For instance, gasoline may contain oxygen-containing chemicals like ethanol, MTBE, or ETBE to enhance combustion. It is important to note that gasoline should be stored in an airtight container to prevent oxidation and water vapour mixing.
The Shukhov cracking process, introduced in 1891, was the first commercial method to increase the percentage of lighter products from crude oil. This process involves using heat, pressure, and catalysts to break down heavier hydrocarbons into smaller, higher-value molecules like gasoline. Reformers also play a role in converting lower octane naphtha into higher octane gasoline through small chemical changes.
