The gallon is a unit of volume in British imperial units and United States customary units. Three different versions are in current use:
Gasoline or petrol is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries.
A filling station is a facility that sells fuel and engine lubricants for motor vehicles. The most common fuels sold are gasoline and diesel fuel.
The fuel protests in the United Kingdom were a series of campaigns held in response to the rising petrol and diesel fuel prices for road vehicle use. There have been three major campaigns amongst many other protests in the 21st century. The first major protest in 2000 was primarily led by independent lorry owner-operators. One group of lorry owner-operators from the South East of England formed a protest group called "TransAction" that protested at oil refineries and fuel depots in Essex. Protests and blockades of oil facilities caused widespread disruption to the supply of petroleum products. The aim of the protests was to secure a reduction in the fuel duty rate on petrol and diesel, which the government refused to enact. After the protest ended, the government did announce a freeze on fuel duties, and promised changes would be made to the way that goods vehicles were taxed, which would include the taxing of foreign vehicles operating on British roads.
Liquid fuels are combustible or energy-generating molecules that can be harnessed to create mechanical energy, usually producing kinetic energy; they also must take the shape of their container. It is the fumes of liquid fuels that are flammable instead of the fluid. Most liquid fuels in widespread use are derived from fossil fuels; however, there are several types, such as hydrogen fuel, ethanol, and biodiesel, which are also categorized as a liquid fuel. Many liquid fuels play a primary role in transportation and the economy.
Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane.
A tank truck, gas truck, fuel truck, or tanker truck or tanker is a motor vehicle designed to carry liquids or gases on roads. The largest such vehicles are similar to railroad tank cars, which are also designed to carry liquid loads. Many variants exist due to the wide variety of liquids that can be transported. Tank trucks tend to be large; they may be insulated or non-insulated; pressurized or non-pressurized; and designed for single or multiple loads. Some are semi-trailer trucks. They are difficult to drive and highly susceptible to rollover due to their high center of gravity, and potentially the free surface effect of liquids sloshing in a partially filled tank.
Fuel dyes are dyes added to fuels, as in some countries it is required by law to dye a low-tax fuel to deter its use in applications intended for higher-taxed ones. Untaxed fuels are referred to as "dyed", while taxed ones are called "clear" or "white".
The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of the volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since the importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy.
Hydrocarbon Oil Duty is a fuel tax levied on some fuels used by most road motor vehicles in the United Kingdom; with exceptions for local bus services, some farm and construction vehicles and aviation, which pay reduced or no fuel duty.
The usage and pricing of gasoline results from factors such as crude oil prices, processing and distribution costs, local demand, the strength of local currencies, local taxation or subsidy, and the availability of local sources of gasoline (supply). Since fuels are traded worldwide, the trade prices are similar. The price paid by consumers largely reflects national pricing policy. Most countries impose taxes on gasoline (petrol), which causes air pollution and climate change; whereas a few, such as Venezuela, subsidize the cost. Some country's taxes do not cover all the negative externalities, that is they do not make the polluter pay the full cost. Western countries have among the highest usage rates per person. The largest consumer is the United States.
Biofuel is fuel that is produced from organic matter (biomass), including plant materials and animal waste. It is considered a renewable source of energy that can assist in reducing carbon emissions. The two main types of biofuel currently being produced in Australia are biodiesel and bioethanol, used as replacements for diesel and petrol (gasoline) respectively. As of 2017 Australia is a relatively small producer of biofuels, accounting for 0.2% of world bioethanol production and 0.1% of world biodiesel production.
An excise, or excise tax, is any duty on manufactured goods that is normally levied at the moment of manufacture for internal consumption rather than at sale. It is therefore a fee that must be paid in order to consume certain products. Excises are often associated with customs duties, which are levied on pre-existing goods when they cross a designated border in a specific direction; customs are levied on goods that become taxable items at the border, while excise is levied on goods that came into existence inland.
The 2007 gasoline rationing plan in Iran was launched by president Mahmoud Ahmadinejad's cabinet to reduce that country's fuel consumption. Although Iran is one of the world's largest producers of petroleum, rapid increases in demand and limited refining capacity have forced the country to import about 40% of its gasoline, at an annual cost of up to USD $7 billion.
The United States federal excise tax on gasoline is 18.4 cents per gallon and 24.4 cents per gallon for diesel fuel. Proceeds from the tax partly support the Highway Trust Fund. The federal tax was last raised on October 1, 1993, and is not indexed to inflation, which increased 111% from Oct. 1993 until Dec. 2023. On average, as of April 2019, state and local taxes and fees add 34.24 cents to gasoline and 35.89 cents to diesel, for a total US volume-weighted average fuel tax of 52.64 cents per gallon for gas and 60.29 cents per gallon for diesel.
The main fuel tax in Australia is an excise tax, to which Goods and Services Tax ("GST") is added. Both taxes are levied by the federal government. In Australia the GST is applied on top of the fuel excise tax. In some cases, businesses may be entitled to exemptions or rebates for fuel excise tax, including tax credits and certain excise-free fuel sources.
In Canada, motor vehicles are primarily powered by gasoline or diesel fuel. Other energy sources include ethanol, biodiesel, propane, compressed natural gas (CNG), electric batteries charged from an external source, and hydrogen. Canada, like most countries, has excise taxes and other taxes on gasoline, diesel, and other liquid and gas motor fuels, and also taxes electricity at various administrative levels. Most provinces and territories in Canada also have taxes on these motor fuels, and some metropolitan areas such as Montreal, Greater Vancouver, and Victoria impose additional taxes.
The use of biofuels varies by region. The world leaders in biofuel development and use are Brazil, United States, France, Sweden and Germany.
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers, petrol pumps, or gas pumps.
A fuel container is a container such as a steel can, bottle, drum, etc. for transporting, storing, and dispensing various fuels.
