Una estación de servicio, bencinera, gasolinera o servicentro es un punto de venta de combustible y lubricantes para vehículos de motor. Aunque en teoría pueden establecerse y comprar libremente, las estaciones de servicio normalmente se asocian con las grandes empresas distribuidoras, con contratos de exclusividad. Generalmente, las estaciones de servicio ofrecen gasolina y gasóleo, ambos derivados del petróleo. Algunas estaciones proveen combustibles alternativos, como gas licuado del petróleo (GLP), gas natural, gas natural comprimido, etanol, gasohol, biodiésel, hidrógeno y keroseno. Asimismo, en algunos países también venden bombonas de butano. Una estación de servicio que permite abastecer a vehículos eléctricos se la denomina electrolinera. Los elementos esenciales de las gasolineras son los surtidores y los depósitos. Según la normativa vigente en España, los depósitos han de ser de doble o de simple pared. Los materiales de los que están fabricados los depósitos son acero o PRFV. En los años noventa, las estaciones de servicio ampliaron su oferta con artículos variados, dando lugar a las tiendas de conveniencia o minimercados, que pasaron a ser habituales en las gasolineras.

A filling station is a facility that sells fuel and engine lubricants for motor vehicles. The most common fuels sold in the 2010s are gasoline (gasoline or gas in the U.S. and Canada, generally petrol elsewhere) and diesel fuel. A filling station that sells only electric energy is also known as a charging station, while a typical filling station can also be known as a fuelling station, garage (South Africa and United Kingdom), gasbar (Canada), gas station (United States and Canada), petrol pump or petrol bunk (India), petrol garage, petrol station (Australia, Hong Kong, New Zealand, Singapore, South Africa and United Kingdom), service station (Australia, New Zealand and United Kingdom), a services (United Kingdom), or servo (Australia). Fuel dispensers are used to pump petrol/gasoline, diesel, Compressed natural gas, CGH2, HCNG, LPG, Liquid hydrogen, kerosene, alcohol fuel (like methanol, ethanol, butanol, propanol), biofuels (like straight vegetable oil, biodiesel), or other types of fuel into the tanks within vehicles and calculate the financial cost of the fuel transferred to the vehicle. Fuel dispensers are also known as bowsers (in some parts of Australia), petrol pumps (in most Commonwealth countries) or gas pumps (in North America). Besides fuel dispensers, one other significant device which is also found in filling stations and can refuel certain (compressed-air) vehicles is an air compressor, although generally these are just used to inflate car tyres. Also, many filling stations incorporate a convenience store, which like most other buildings generally have electricity sockets; hence plug-in electric vehicles can be recharged. The convenience stores found in filling stations typically sell candy, soda/pop, snacks and, in some cases, a small selection of grocery items. Some also sell propane or butane and have added shops to their primary business. Conversely, some chain stores, such as supermarkets, discount superstores, warehouse clubs, or traditional convenience stores, have provided filling stations on the premises.
