Costco Gas Prices Today in the United States

Costco runs a gas station at most of its US warehouses, selling Kirkland Signature fuel to members, usually for less than the stations nearby. Each warehouse sets its own price, so what you pay can change from one Costco to the next, even within the same city.

This page tracks every Costco gas station in the United States and is updated daily. Below you’ll find the national averages for regular, premium and diesel, a search for any station, a 30-day price history, today’s cheapest stations, and a page for each state with prices at every warehouse in it.

Costco gas guides for the United States

Most Costco warehouses in the United States have a gas station out front: 600 of the 640 (see every Costco gas station location). Fuel margins are thin on purpose. The membership covers the profit, the fuel is bought from the same regional terminals as the name-brand stations down the road, and the posted price typically lands 20 to 40 cents a gallon below them. A new warehouse tends to pull the neighborhood down with it, though those stations almost never match.

What you pay still depends on which warehouse you visit. Each station sets its own price, generally once a day, and two locations in the same metro can differ by 10 cents or more. The cheaper one is not always the one you would expect — the averages and rankings on this page are there for that reason.

The fuel is Kirkland Signature and Top Tier certified. Every station sells regular (87) and premium (91 or 93, depending on the region; see today’s Costco premium gas price), there is no mid-grade, and about one station in nine sells diesel; see Costco diesel prices for which ones. A membership card is required to pump; payment is Visa, debit, or a Costco Shop Card, and the gas station typically keeps longer hours than the warehouse. At busy locations, the queue is part of the deal, especially on weekends.

The ranking is regular gasoline only, and it reshuffles. Each warehouse prices itself, so a station that looks like a steal on Monday can be unremarkable by Friday. Premium and diesel, where they are sold, do not always follow the same order.

Puerto Rico pumps price in USD per litre, so it is left out of the US average and rankings above.

A Costco gas station is set up to move cars, not to browse. Lanes are one-way, the hoses reach either side of the vehicle, and a safety attendant is on site; there is no convenience store and no cash. Hours typically start around 6 a.m. on weekdays and run later than the warehouse, with a shorter schedule on weekends. The pumps close on the same major holidays — New Year’s, Easter, Memorial Day, the Fourth of July, Labor Day, Thanksgiving, and Christmas; see Costco gas holiday hours for this year’s dates. Every station’s schedule, with a live open-now badge, is on the Costco gas hours page.

Costco is the only warehouse club that sells Top Tier gasoline at every location, so the cheap pump is not a lesser grade. Some Costco Business Centers have pumps too, open to any member; see Costco Business Center gas for which ones and their prices. Card payments take a hold of up to $150 until the fill posts, and the Executive 2% reward does not apply to gasoline.

Costco gas in the United States: common questions

How much is gas at Costco today?

Costco gas stations in the United States average $4.275 a gallon for regular as of the October 31, 2026 reading, across 599 stations that reported. Individual stations run from $3.039 at Wilmington to $6.139 at Eureka. Each station sets its own price, so check the one you are driving to.

Where is the cheapest Costco gas in the United States today?

Wilmington posts the lowest Regular price in the United States, $3.039 as of the October 31, 2026 reading — $3.100 under Eureka, the most expensive of the 599 stations reporting.

Which states have the cheapest and most expensive Costco gas?

North Carolina averages $3.186 for Regular as of the October 31, 2026 reading, the lowest of the 46 states ranked on this page; California is the highest at $5.453. Fuel taxes, blend rules and transport costs drive most of that $2.267 gap.

Do Costco gas prices differ from state to state?

Yes, and by more than most people expect. Every warehouse sets its own price, generally once a day, and fuel taxes, blend rules and transport costs move whole states together. Today the state averages span $2.267. Two warehouses in the same metro set their prices separately as well, so the cheapest fill is not always in the cheapest state.

How often are these Costco gas prices updated?

Once a day. Every station's posted price is collected in one daily pass, and the averages and rankings on this page are rebuilt from that reading — so the pump can differ from what you see here, especially late in the day.

Do you need a Costco membership to buy gas?

Yes — a Gold Star, Executive or Business membership card has to be scanned at the pump before it will dispense, though a Costco Shop Card also works for non-members.

What payment methods does the Costco gas station accept?

Visa, PIN debit and the Costco Shop Card; US Costco fuel pumps take no cash and no Mastercard, American Express or Discover.
