How many service stations are there in the United States?
The NACS, the association for convenience and fuel retailing, reports that there are more than 150,000 fueling stations across the United States. 127,588 of these stations are convenience stores selling fuel. The rest are gas-only stations, grocery stores selling fuel, marinas, etc.
Do the major oil companies own all the service stations in this country?
Who owns the rest of the stations?
Independent owners. They may own just one station, or they could own several stations, or they could own hundreds of stations.
Can these independent owners also sell the major brands of gasoline?
是的。Independents and jobbers can sell gasoline under the brand of one major company or multiple major companies, as well as have their own brand of fuel.
Why is the price of gasoline so much higher in other countries?
Many countries assess higher tax rates and use the revenue for their general fund budget. For example, ten countries in Europe, Belgium, Finland, France, Germany, Greece, Italy, the Netherlands, Norway, Sweden, and the United Kingdom assess more than $3 in taxes on every gallon of gasoline,according to the Tax Foundation.
When I am behind the wheel, how can I get more miles per gallon?
Besides changing driving habits, what can I do to improve vehicle fuel efficiency?
Maintain your vehicle. Have your car tuned regularly, keep air filters clean, and make sure tires are properly inflated. An engine tune-up can improve car fuel economy by an average of one mile per gallon; under-inflated tires can reduce it by that amount. Don’t warm up your car for too long on cold mornings. Experts say that your car only needs a 30 second warm-up before you can start driving in winter. Cool your car responsibly on hot days. Less use of your air conditioner can improve fuel economy by as much as two miles per gallon, but today’s air conditioners create less drag on your engine than driving with the windows down. Also, you should clean out your car—not only will it make it look nicer, but reducing weight can increase fuel efficiency.
More fuel-efficient vehicles can save gasoline. A highly fuel-efficient vehicle could potentially cut gasoline use in half or more. How much depends on the vehicle and driving habits and needs. If a less fuel-efficient car requires 20 gallons of gasoline a week compared with 10 gallons for a highly fuel-efficient vehicle, more than 500 gallons of gasoline could be saved annually.
What about ethanol?
Can I avoid fuel evaporation and loss by keeping my tank almost full?
Does it help to fill up in the morning when fuel is cool?
很少。虽然汽油在变得更热（减少给定卷中的能量内容）时，汽油膨胀是真实的，但扩展只是关于一个百分之一for every 15 degrees F. Moreover, storage tanks at gasoline stations are buried several feet underground, helping to insulate fuel and keep temperature relatively constant. The benefits, if any, of filling up in the morning versus the evening would be hard to notice.
How much tax do we pay on a gallon of gasoline?
Federal, state, and local government taxes also contribute to the retail price of gasoline. The federal excise tax is currently 18.3¢ per gallon, and there is an additional Leaking Underground Storage Tank fee of 0.1¢ per gallon. As of July 1, 2017, state taxes on gasoline, including state and local government taxes and fees, averaged 27.3¢ per gallon. County and city taxes can have a significant impact on the price of gasoline in some locations. See the U.S. Energy Information Administration'sGasoline Explained: Factors Affecting Gasoline Prices.
What Does the Government Do with the Money?
Do most customers pump their own gasoline?
Why are prices posted in fractions?
I see gasoline trucks traveling on the road daily. Are they delivering product right from the refinery?
Sometimes, but most often they are delivering fuel to a service station from a bulk terminal that has been supplied by pipeline or marine terminal. As of January 1, 2017, there are 137 refineries operating in the United States. From the refineries, the products are transported to the terminals by barge, truck or pipeline. The majority of the product is moved by underground pipelines and stored in large above-ground storage tanks at1,303 locations全国各地。这些位置称为终端。运输卡车，特别是旨在安全地携带石油产品，在终端拾取产品，并将其送到维修站的地下储罐。
API’s historical files note that the first "filling" station was opened in Seattle in 1907 by Standard Oil of California, which is now Chevron Co. USA. The "filling" station included a hose that dispensed gasoline directly into the vehicle from an elevated tank. Charles Duryea had invented the gasoline-powered horseless carriage in 1893, but there were few owners in those early years. They purchased gasoline from bulk depots, often in five gallon containers. The industry was transformed in 1908 when Henry Ford mass- produced the first Model T, and many retail locations began selling gasoline at the curb. The first "drive-in" service station opened on December 1, 1913 in Pittsburgh, Pennsylvania.
I sometimes notice stations closing temporarily and digging up the site. What were they doing?
他们可能做出改进保护the environment, especially against potential leaks from underground storage tanks. By law, older tanks had to be replaced, but newer tanks can be "upgraded" to include improved leak detection systems and protection against future corrosion.
Does this apply only to service stations?
No, the law covers all underground tanks containing petroleum products. Police department, school districts, automobile dealers and many other facilities have underground storage tanks on their property. The only exemptions are farm or residential tanks of 1,100 gallons or less capacity; and residential commercial or industrial heating oil tanks used for consumptive use on the premise where the heating oil is stored.
How do I get more information on this requirement?
Congress passed Subtitle I of the Resource Conservation and Recovery Act in 1984, which required the U.S. Environmental Protection Agency to develop a comprehensive program to protect, detect and correct releases from underground storage tanks. The EPA Office of Underground Tanks was organized to develop the technical standards, and those regulations were issue 4 in September 1988. The low provided for a 10-year phase-in of the requirement, so the work had to be completed by December 1998. The EPA published revised Underground Storage Tank Regulations in 2015.
