Filling station

• 1. Introduction

  ›

  Filling stations are so ordinary that most drivers barely notice them. Yet on a summer day in 1888, Bertha Benz pulled a sputtering automobile into a city pharmacy in Wiesloch, Germany, and asked to buy fuel. That moment, the maiden trip of the first automobile from Mannheim to Pforzheim, marks the earliest known instance of a vehicle being refueled outside someone's own garage. What began at a pharmacy counter has grown into a global infrastructure handling motor fuels, convenience groceries, road safety legislation, underground contamination, and the slow march toward electric vehicles. How did we get from Bertha Benz at a pharmacy counter to over 114,000 stations across the United States alone? And what hidden costs, health risks, and regulatory battles has the filling station carried along the way?

• 2. A Language of Its Own

  ›

  "Petrol" was originally a brand name, not a generic word. It belonged to Carless Refining and Marketing Ltd, which sold a petroleum distillate as a mineral oil solvent. That brand name swept across the English-speaking world outside North America, giving Britain the "petrol station" and Ireland the "forecourt." In North America, gasoline engines became the dominant technology, and so "gas" became the common shorthand, with the station itself called a "gas station" or "service station" across the United States, Canada, and the Caribbean. Canada adds a regional twist: in some areas, residents still ask directions to the "gas bar." Australians shortened "service station" to "servo." In India, Pakistan, and Bangladesh, the phrase "petrol pump" or "petrol bunk" does the job. Japanese speakers have a commonly used term of their own, though the abbreviation SS, for service station, is also widely understood. The same product sold through functionally identical equipment carries a different name on every continent, shaped by the historical accident of which fuel brand or engine type arrived first.

• 3. From Pharmacy to Drive-Through

  The world's first purpose-built gas station was constructed in St. Louis, Missouri, in 1905 at 420 South Theresa Avenue. Two years later, Standard Oil of California, now known as Chevron, opened a second station in Seattle, Washington, at what is now Pier 32. Reighard's Gas Station in Altoona, Pennsylvania claims a 1909 origin and bills itself as the oldest surviving filling station in the country. Before dedicated stations existed, automobile drivers pulled into hardware stores, general stores, or even blacksmith shops to top up their tanks. Henry Ford's decision to sell cars the middle class could afford drove demand that these makeshift arrangements could not meet. The drive-in format came next. The first drive-in station in the United States opened in 1912 in Columbus, Ohio, at the corner of Young and Oak streets, operated by Standard Oil of Ohio. A motorist drove in the front, had the tank filled, and exited the back. On the 1st of December 1913, Whitehill-Gleason Motors opened for Gulf Refining Company in Pittsburgh on Baum Boulevard and St Clair's Street. On that first day, the station sold 30 US gallons of gasoline at 27 cents per gallon. It was also the first architect-designed station and the first to hand out free road maps, a practice that became standard across the industry for decades.

• 4. Underground Infrastructure

  ›

  Beneath nearly every forecourt in the world sits a network of buried tanks and pipes that most drivers never think about. Fuel offloaded from tanker trucks flows by gravity through a capped perimeter opening into underground tanks. From those tanks, pipes carry fuel up to the dispenser pumps. Vapor recovery systems thread through the entire arrangement, capturing fuel vapors, liquefying them, and feeding them back into the lowest-grade tank on site. Older stations ran a separate pipe for each fuel type and each dispenser. Newer designs route a single pipe to each dispenser, with smaller pipes for individual fuel grades bundled inside. A distinct innovation arrived in Finland in 1993, when U-Cont Oy Ltd developed and patented the underground modular filling station. As proof of the model's speed, the company set an unofficial world record when a modular station was assembled in Helsinki in under three days, groundwork included. Safety testing for these modular stations has been conducted at a simulator in Kuopio, Finland, including tests involving burning cars and controlled explosions. Above-ground modular versions were built in the 1980s across Eastern Europe and the Soviet Union, but the design did not spread to Western Europe because of fire safety concerns.

  Gasoline contains a group of hydrocarbons known as BTEX: benzene, toluene, ethylbenzene, and xylenes. Prolonged exposure to toluene can cause permanent damage to the central nervous system. Chlorinated solvents found in fuel can harm the liver and kidneys. Benzene is the most serious: it causes leukemia and is linked to non-Hodgkin lymphoma and multiple myeloma. People who work at filling stations, live near them, or attend school close to them face an elevated lifetime cancer risk, with the risk rising further when multiple stations are clustered nearby. Some evidence connects living near a station to childhood leukemia. Gas station attendants have shown higher levels of chromosomal deletions, higher rates of miscarriage, and self-reported symptoms including headaches, fatigue, throat irritation, and depression. Short-term spikes in benzene exposure happen every time a tanker truck makes a delivery. Soil and groundwater contamination is another layer of the problem. Underground storage tanks were typically made of steel in the United States and were prone to corrosion. National attention landed on the issue in 1983 after a television program documented drinking water contamination from a Mobil station in the Canob Park neighborhood of Richmond, Rhode Island. Investigators found that the station's tanks had been leaking gasoline into the local water supply since the station opened in 1968. That prompted regulations banning those tank types in 1985. Because tanks at stations that closed before 1986 were often never recorded, many old tanks remain buried under redeveloped land, quietly poisoning soil, groundwater, and indoor air.

• 6. Property Values and Cleanup Costs

  ›

  An analysis of residential properties in Cuyahoga County, Ohio found that proximity to a registered leaking tank lowered home values by about 17% when the property was within 300 feet, or roughly one city block, of the site. A separate analysis in Xuancheng, China found that active filling stations suppress property values by 16% within 100 metres and by 9% between 301 metres and 600 metres away. The cost of cleaning up contaminated former station sites across the United States runs into the billions of dollars in total, though no precise national figure is known. Because former stations tend to be small parcels, the cost per acre of rehabilitation is disproportionately high compared to larger industrial brownfields. In Canada, individual cleanups have stretched on for decades and consumed millions of dollars in both remediation costs and legal fees to establish who among individuals, governments, or corporations bears the liability.

  The first self-service filling station in the United States opened in Los Angeles in 1947, operated by Frank Urich. Two years later, Canada's first self-service station opened in Winnipeg, Manitoba, run by a company called Henderson Thriftway Petroleum, owned by Bill Henderson. Before 1970 in the United States, full service was the norm and self-service was rare. Today the reverse holds almost everywhere, except in a handful of places that have held the line. New Jersey prohibited self-service in 1949 under the Retail Gasoline Dispensing Safety Act, after lobbying by service station owners. The law's stated rationale centers on fire hazards: it requires attendants to control fueling so that engines are switched off and smoking is prevented. The only exception within New Jersey is a station next to Joint Base McGuire-Dix-Lakehurst in Wrightstown. Oregon prohibited self-service in a 1951 statute that listed 17 separate justifications, including flammability, crime risk from customers leaving vehicles, toxic fumes, and job preservation. Oregon voters rejected a 1982 ballot measure that would have legalized self-service. In May 2017 the governor signed a bill allowing self-service in counties with populations of 40,000 or fewer, effective January 2018. A 2023 law signed by Governor Tina Kotek extended the right statewide, though stations are still required to offer full service to customers who request it. In Brazil, self-service has been illegal under federal law since 2000. The law was introduced by Federal Deputy Aldo Rebelo, who claims it preserved 300,000 fuel attendant jobs nationwide. Japan legalized self-service in 1998 following the abolition of the Special Petroleum Law, but even today at least one attendant must be present at all self-service stations to monitor safety.

• 8. Declining Numbers, Global Spread

  ›

  The United Kingdom recorded roughly 40,000 filling stations at their peak in the mid-1960s. By 1992 that number had fallen to around 18,000, and by the time current figures were compiled it stood at 8,385. The United States counted 121,446 stations in 2002, falling to 118,756 in 2007 and 114,474 in 2012. Canada held about 20,000 stations in 1989 and dropped to 12,684 by December 2008. Japan peaked at 60,421 stations in 1994 and reached 40,357 by the end of 2009. China, by contrast, reported roughly 106,000 stations at the end of 2018. India counted 60,799 stations as of November 2017. The first alternative fuel station in the United States opened in San Diego, California, in 2003, operated by Pearson Fuels. On the 26th of September 2019, RS Automotive in Takoma Park, Maryland became, according to Maryland officials, the first conventional filling station in the country to convert entirely to an electric vehicle charging station. The global station count continues to shift as electric vehicles expand their range and charging networks spread, but the basic model Bertha Benz encountered at a pharmacy in 1888 still governs the daily routine of hundreds of millions of drivers.
