Gasoline and diesel usage and pricing in the context of "Petrol station"

A filling station (also known as a gas station [US] or petrol station [UK/AU]) is a facility that sells fuel and engine lubricants for motor vehicles. It serves as a local fuel depot and retailer who receive fuel products from refineries (via regular tank truck resupplies), keep the fuels in (typically underground) storage tanks, and distribute individual product to motorist consumers at a daily varied price.

The most common fuels sold are motor fuels such as gasoline (a.k.a. petrol, often as multiple products according to different octane ratings) and diesel fuel, as well as liquified petroleum gas (LPG, i.e. autogas), compressed natural gas, compressed hydrogen, hydrogen compressed natural gas, liquid hydrogen, kerosene, alcohol fuels (like methanol, ethanol, butanol, and propanol), biofuels (like straight vegetable oil and biodiesel), or other types of alternative fuels. Fuel dispensers are used to pump fuel into the fuel tanks within vehicles, gauge the volume of fuel transferred to the vehicle, and calculate the financial cost the consumer must pay. Besides fuel pumps, another significant device found in filling stations and capable of refueling certain (compressed-air) vehicles is an air compressor. However, these are generally used to inflate car tires.

The PCE price index (PCEPI), also referred to as the PCE deflator, PCE price deflator, or the Implicit Price Deflator for Personal Consumption Expenditures (IPD for PCE) by the Bureau of Economic Analysis (BEA) and as the Chain-type Price Index for Personal Consumption Expenditures (CTPIPCE) by the Federal Open Market Committee (FOMC), is a United States-wide indicator of the average increase in prices for all domestic personal consumption. It is currently benchmarked to a base of 2017, consistent with the US National Accounts. Using a variety of data including U.S. Consumer Price Index and Producer Price Index prices, it is derived from the largest component of the GDP in the BEA's National Income and Product Accounts, personal consumption expenditures. PCE data is published monthly by the Bureau of Economic Analysis (BEA) as part of the National Income and Product Accounts (NIPA).

The personal consumption expenditure (PCE) measure is the component statistic for consumption in gross domestic product (GDP) collected by the United States Bureau of Economic Analysis (BEA). It consists of the actual and imputed expenditures of households and includes data pertaining to durable and non-durable goods and services. Essentially, it is a measure of goods and services targeted towards individuals and consumed by individuals. The less volatile measure of the PCE price index is the core PCE (CPCE) price index, which excludes the more volatile and seasonal food and energy prices (e.g., oil, natural gas, and electricity).

Carpooling is the sharing of car journeys so that more than one person travels in a car, and prevents the need for others to have to drive to a location themselves. Carpooling is considered a Demand-Responsive Transport (DRT) service.

By having more people using one vehicle, carpooling reduces each person's travel costs such as: fuel costs, tolls, and the stress of driving. Carpooling is also a more environmentally friendly and sustainable way to travel as sharing journeys reduces air pollution, carbon emissions, traffic congestion on the roads, and the need for parking spaces. Authorities often encourage carpooling, especially during periods of high pollution or high fuel prices. Car sharing is a good way to use up the full seating capacity of a car, which would otherwise remain unused if it were just the driver using the car.

Headline inflation is a statistical measure of aggregate price movement within an economy, usually expressed as percentage change in the Consumer Price Index (or other price indices) over a specific time period. It is typically measured using a comprehensive array of goods and services, including commercial products such as food and energy (e.g., oil and gas), which tend to be much more subject to price fluctuations and prone to inflationary spikes. On the other hand, "core inflation" (also non-food-manufacturing or underlying inflation) is commonly calculated from a consumer price index minus the volatile food and energy components.

Headline inflation, alongside core inflation, are among the key economic data produced by various national statistical agencies. It is often used as standard indicator of changes in cost of living and is being targeted by most central banks to influence price stability.
