The fuel that powers cars, known as gasoline or petrol, is a product derived from crude oil. This oil is extracted from underground and underwater reservoirs, where it is formed from the remains of tiny plants and animals that lived millions of years ago. After being extracted through wells, the oil is stored in large tanks and transported to refineries, where it is heated to a high temperature and transformed into a variety of raw materials. These materials are then selectively reconfigured into new products, including gasoline, which undergoes further processing and blending before being delivered to retail fueling stations.

Crude oil extraction
The extraction of crude oil is a complex process that involves multiple steps and requires a range of specialised equipment and expertise. Geologists and geophysicists play a crucial role in this process, using seismic surveys and other instruments to locate underground reservoirs that may contain oil. Once a potential reservoir has been identified, the drilling process can begin.
The first step in the drilling process is to prepare the site by constructing the necessary infrastructure, including pads, access roads, and safety features such as noise barriers. Next, the drill rig is transported to the location and assembled. After assembly, the drilling can begin. A long hole, or "surface hole", is drilled down to a certain depth, and a steel casing is placed inside to provide structural support. This casing is typically cemented in place.
Once the drilling reaches a certain depth, usually about 1000 feet above the target area, the direction of the drilling changes. The hole is turned horizontal and extended outward, following the same rock bed. This technique, known as horizontal drilling, minimises the impact on the land above and allows access to oil and gas across a longer distance. It also reduces the number of well sites required.
After drilling, the oil is unlocked from the rock using a process called fracking. Fracking fluid, which is primarily composed of water and sand with a small percentage of chemicals, is pumped at high pressure through the holes created by drilling. This creates tiny cracks in the shale rock, releasing the oil and gas trapped inside. The fracking fluid is then recovered and recycled for future use. Once fracking is complete, production begins, with the oil and gas flowing up from the wellbore for collection and subsequent processing and distribution.
Overall, the extraction of crude oil is a complex and technologically advanced process that requires careful planning and monitoring to ensure safety and environmental sustainability.

Petroleum refining
The car fuel we use comes from a long and complex process, starting with crude oil, a fossil fuel, being extracted from underground and underwater reservoirs. Crude oil is a mixture of liquid hydrocarbons, created from the remains of tiny plants and animals that lived millions of years ago. These remains were covered by sediment and subjected to intense heat and pressure, forming the substance we call petroleum or crude oil.
The process of turning crude oil into fuel begins with extraction. Crude oil is extracted through wells and stored in large tanks before being transported to refineries. This is done via pipelines, ships, barges, and trains. Once the crude oil reaches the refinery, it undergoes fractional distillation, where it is heated to around 600 degrees Celsius. The oil is boiled, and the vapour created is injected into a distillation tower. This process separates the crude oil into a variety of raw materials, which are selectively reconfigured into new products. These new products include gasoline, which is used as fuel for spark-ignited internal combustion engines.
The specific processes and additives used to create the final product can vary, and the exact origin of the gasoline sold at fuelling stations is often challenging to identify. However, the fundamental steps of refining, transport, storage, and blending remain consistent. The finished motor gasoline is then delivered to retail outlets and fuelling stations via tanker trucks.
The development of the internal combustion engine in the late 19th century sparked interest in gasoline-like fuels. The early engines used a volatile hydrocarbon obtained from coal gas, but the invention of the "spray nozzle" carburetor allowed for the use of less volatile fuels. The Shukhov cracking process in 1891 was a pivotal moment, as it enabled the breakdown of heavier hydrocarbons in crude oil, increasing the yield of lighter products through a process more efficient than simple distillation.

Transport and storage
The transport and storage of car fuel is a complex process that involves multiple stages and a range of different vehicles. Firstly, the extraction of crude oil through wells is the initial step in the fuel production process. The crude oil is then stored in large tanks before being transported to refineries via pipelines, ships, barges, and trains. This step is crucial in ensuring a steady supply of oil for the refining process.
Once the crude oil reaches the refineries, it undergoes fractional distillation, where it is heated to around 600 degrees Celsius. This process separates the crude oil into various raw materials, which are then further refined to create different products, including base gasoline. The base gasoline is then transported through pipelines, ships, and barges to distribution centers, where it is stored in large tanks. These distribution centers serve as hubs for the fuel to be delivered to gasoline stations.
At the gasoline stations, the base fuel is blended with special additive packages, creating branded gasolines with unique characteristics. This process allows for differentiation in the market and caters to different vehicle types and performance requirements. The gasoline is then stored in separate underground tanks for regular and premium grades, as well as diesel, depending on the retailer. Some retailers also offer mid-grade gasoline, which is made by blending regular and premium gasoline at the pump.
In addition to gasoline, alternative fuels such as ethanol, biodiesel, and natural gas are also gaining popularity in the market. Ethanol and biodiesel were some of the first fuels for automobiles but were later replaced by gasoline and diesel made from crude oil. Today, most motor gasoline contains up to 10% ethanol, and biodiesel is often blended with petroleum diesel. Natural gas, on the other hand, is transported through high-pressure, long-distance pipelines to consumers. It undergoes a complex processing and purification procedure to remove contaminants and impurities, ensuring that it meets specific quality measures for safe transportation and use.

Blending and additives
The process of converting crude oil into gasoline involves several stages, including refining, transportation, storage, and blending. Crude oil is extracted from underground and underwater reservoirs and transported to refineries, where it undergoes fractional distillation. Following distillation, the gasoline is typically pumped through pipelines to large storage terminals. From these terminals, the product is loaded into tanker trucks and delivered to blending terminals for processing into finished motor gasoline.
At the blending terminals, fuel ethanol is often added to the gasoline. This blending process is crucial to enhance the octane rating of the gasoline, which measures its ability to resist premature ignition or "knocking". Knocking reduces efficiency in reciprocating engines. Historically, tetraethyl lead was used to increase the octane rating, but due to health hazards, it has been discontinued from automotive gasoline. However, leaded gasolines are still used in aviation, off-road motor vehicles, and racing car engines.
The blending process also allows for the addition of unique additives to the base gasoline. These additives are used to meet higher standards, such as the Top Tier™ detergent gasoline specification. A study by AAA in 2016 revealed that gasoline meeting this higher standard can keep engine components significantly cleaner compared to fuels with the minimum required detergent level.
It is important to note that the specific sources and blends of crude oil can vary among refiners, and the final product may be a mix of crude oils from various domestic and foreign sources. This variation in sources and blends can be attributed to factors such as the relative cost and availability of crude oil from different suppliers.

Gas station distribution
The journey of gasoline from its origin as crude oil to the finished product in your car's fuel tank is a complex process. Gasoline, or petrol, is a petrochemical product derived from the fractional distillation of petroleum. Crude oil, a fossil fuel, is extracted from underground and underwater reservoirs through wells and stored in large tanks. It is then transported to refineries via pipelines, ships, barges, and trains.
At the refinery, the crude oil is heated to its boiling point of around 600 degrees Celsius, and the vapor is injected into a distillation tower. This separates the crude oil into various raw materials, which are then selectively reconfigured into new products. These products include gasoline, which is chemically enhanced with additives to improve its performance.
After the refining process, the gasoline is typically pumped via pipelines to large regional storage terminals. From these terminals, it is loaded into tanker trucks for delivery to specific gas stations. The United States, for example, has over 100,000 retail outlets that receive gasoline from these blending terminals.
Different companies that own service stations in the same area may purchase their gasoline from the same bulk storage and distribution terminal. Many gas stations are unbranded dealers, selling gasoline produced by various companies. Even branded stations may not necessarily sell the gasoline their company produces. Additionally, the gasoline may be blended with fuel ethanol at smaller terminals before being delivered to the gas stations.
