The journey of gasoline from oil rigs to fuel tanks is a complex process. Gasoline begins as crude oil, a fossil fuel that is formed from the remains of dead plants and animals exposed to heat and pressure over millions of years. Crude oil is transported via pipelines, ships, or barges to refineries, where it is refined into gasoline and other products. From the refineries, gasoline is transported through various means to distribution centres and then to retail outlets, where it is stored in tanks until dispensed into consumers' vehicles.

Gasoline is transported via pipelines, ships, railways, and tanker trucks
Gasoline is transported in several ways, including via pipelines, ships, railways, and tanker trucks. Each method plays a crucial role in ensuring the distribution of gasoline from refineries to local gas stations and, ultimately, to consumers.
Pipelines are a vital component of the fuel transportation system. They are responsible for transporting large quantities of hazardous liquids, such as gasoline, over long distances. The United States, for example, relies heavily on pipelines, with over 200,000 miles of pipelines dedicated to carrying natural gas, crude oil, and refined products. These pipelines are essential for delivering energy products to industries and consumers, powering the economy and our daily lives.
For regions without direct access to pipelines, railways often come into play. Railroads have been instrumental in transporting crude oil, especially in areas with limited pipeline infrastructure. In the United States, railroads have significantly increased the accessibility of energy resources and contributed to reducing the cost of gasoline and home heating oil. Technological advancements have led to increased crude oil production, and railroads have risen to the challenge, transporting over 265,000,000 barrels of Bakken crude in 2014.
In addition to pipelines and railways, ships are also utilized for gasoline transportation, particularly in marine environments. This mode of transportation is part of the broader energy infrastructure network, which includes pipelines, trucking, and railways.
Finally, tanker trucks play a crucial role in the final leg of the gasoline distribution process. These trucks are designed to carry liquids or gases on roads, delivering gasoline from storage facilities to local gas stations. They are often insulated, pressurized, and designed for single or multiple loads. The largest tanker trucks can carry over 44,000 litres of gasoline, ensuring efficient distribution to service stations.

Gasoline is stored in large tanks at storage facilities
The storage facilities are not the first stop in the gasoline's journey. Before arriving at the storage facilities, gasoline is transported via pipelines, ships, and railways from refineries. It is also sometimes transported by trains, although this method is less popular due to the high risk of spills and other accidents.
Once the gasoline arrives at the storage facilities, it is stored in large tanks until it is ready to be distributed to gas stations. These tanks are usually underground and separate for regular and premium gasoline, as well as diesel if the retailer sells it. The tanks at the storage facilities are much larger than those at the gas stations, as they are meant to hold a greater supply of fuel.
Finally, the gasoline is loaded onto tanker trucks for delivery to the gas stations. At this point, special additive packages are blended in, turning the base fuels into branded gasolines with unique characteristics. These additive packages are formulated by companies to create their own unique, high-quality blends.

Gasoline is blended with ethanol to meet EPA requirements
Gasoline is blended with ethanol to meet Environmental Protection Agency (EPA) requirements. Ethanol is a renewable fuel made from plant materials known as biomass. In the United States, 94% of ethanol is produced from the starch in corn grain. The addition of ethanol to gasoline boosts the octane level, and the resulting fuel is known as E10 (10% ethanol, 90% gasoline). This blend is approved for use by all automotive vehicle manufacturers in the US and helps to reduce air pollution.
Ethanol has a higher octane number than gasoline, and its addition prevents engine knocking and ensures drivability. The blend also improves the energy balance of ethanol as the feedstocks are either waste or coproducts of another industry, such as wood or crop residues. The use of biomass to power the conversion of non-food-based feedstocks into cellulosic ethanol further reduces the amount of fossil fuel energy required in production.
The EPA has allowed the summertime sales of gasoline with a higher blend of ethanol, such as E15 (15% ethanol), to increase fuel supply and support farmers and energy security. While adding ethanol to gasoline can increase smog pollution in hot weather, research has shown little difference in emissions between E15 and E10 blends. The EPA estimates that E15 is, on average, about 25 cents cheaper per gallon than E10.
Flex-fuel vehicles can use any ethanol-gasoline blends up to E85 (83% ethanol). The impact of ethanol on vehicle fuel economy depends on the ethanol content and whether the engine is optimised for gasoline or ethanol.

Gasoline is delivered to retail outlets by tanker trucks
Tanker trucks play a crucial role in the gasoline supply chain, which includes five main parts: producing or importing crude oil, importing gasoline, refining crude oil into gasoline, blending gasoline with ethanol at distribution terminals, and selling the gasoline at retail stations. The trucks are used to transport gasoline from large storage terminals to smaller blending terminals, where it is processed into finished motor gasoline. This is also where fuel ethanol is typically blended into the gasoline to boost its octane level and meet Environmental Protection Agency (EPA) requirements for oxygenated fuels.
From the blending terminals, tanker trucks deliver the finished motor gasoline to retail outlets across the United States. These outlets include more than 100,000 retail outlets, including branded and unbranded service stations. The trucks are responsible for replenishing the fuel supply at each station, ensuring that motorists have access to gasoline. At the gas station, delivery drivers and retailers check the gasoline quality once more before it is pumped into designated holding tanks.
The use of tanker trucks to deliver gasoline to retail outlets offers several advantages, including the ability to transport large quantities of fuel over long distances efficiently. However, it is important to note that these trucks can be difficult to drive and are susceptible to rollover due to their high center of gravity. Overall, tanker trucks play a vital role in ensuring the continuous supply of gasoline to retail outlets, enabling motorists to access the fuel they need for their vehicles.

Gasoline is pumped from segregated pipes into designated holding tanks
Gasoline is a product of crude oil, which is extracted from the ground and undergoes a series of processes before becoming the fuel we use in our vehicles. Once the crude oil is extracted, it is sent to petroleum refineries, where it is broken down into its various components and reconfigured into new products, such as gasoline. This is then transported via pipelines, ships, or railways to terminals. At these terminals, detergents, additives, and ethanol are blended to formulate different types of gasoline.
From the terminals, the gasoline is then loaded onto tanker trucks and transported to large storage facilities. These storage facilities hold large tanks of gasoline until it is ready to be distributed to local gas stations. Once at the gas stations, delivery drivers and retailers perform checks to ensure the gasoline meets the required standards. The gasoline is then pumped from the tanker trucks through segregated pipes into designated holding tanks underground.
The number of holding tanks at a gas station can vary, but generally, there are separate tanks for high octane, low octane, and diesel. Some stations may also offer ethanol blends, which are created by mixing standard gasoline with ethanol. The different grades of gasoline are achieved by mixing the gas from the high and low octane tanks at different ratios.
When a customer selects a gas grade at the pump, the gas is drawn from the corresponding tank and pumped into their vehicle's fuel tank. This completes the long journey of gasoline, from its extraction as crude oil to its final use in a vehicle. It is important to note that the fueling system of a vehicle needs to be maintained properly to utilise the gasoline efficiently.
