Costco will open its first standalone gas station this summer in Mission Viejo, California, a 17,000-square-foot, 40-pump facility that operates without an attached warehouse. The move marks a new chapter for a retailer that has sold fuel since 1995 but has never before untethered its pumps from one of its big-box stores.
The station is expected to open in June 2026, as CNBC Select reported, citing USA TODAY. A second standalone station is planned for Honolulu, Hawaii, in 2027. Both locations will remain members-only, meaning drivers still need a $65 Gold Star or $130 Executive membership card to fill up.
For families watching every dollar at the pump, the question is straightforward: does the membership fee pay for itself in fuel savings alone? The data suggests it can, and then some.
GasBuddy price data accurate as of Thursday, March 26, 2026, shows meaningful per-gallon gaps between Costco stations and traditional competitors in three metro areas. In Los Angeles, a conventional station charged $5.95 per gallon while Costco charged $5.39, a 56-cent spread. In Chicago, the gap was 19 cents ($4.48 versus $4.29). In Rochester, New York, it was 20 cents ($3.91 versus $3.71).
Average those three spreads and you land around 37 cents per gallon. Patrick De Haan, head of petroleum analysis at GasBuddy, has said the average American burns roughly 600 gallons a year. Multiply 37 cents by 600 gallons and the annual savings reach about $222, well above the $65 basic membership fee.
In Southern California, where gas prices have surged by 40 cents in just two weeks during recent refinery constraints, the savings can be even steeper. The New York Post reported that Costco gas is typically priced about $0.05 to $0.40 below local competitors, a range that matters a great deal when the baseline is nearly six dollars a gallon.
Until now, every Costco gas pump in the country has sat in the parking lot of a warehouse store. That model works, but it limits where Costco can sell fuel. Zoning, lot size, and lease terms for a 150,000-square-foot warehouse are different animals than a gas-only parcel.
Decoupling the pumps from the warehouse lets Costco plant fuel stations in places where a full store would never fit. Mission Viejo, in Orange County, is the test case. If it works, the Honolulu location follows a year later, and there is no reason to think the model stops there.
Costco's leadership is clear-eyed about what cheap gas does for the rest of the business. During the company's Q2 2026 earnings call, executive vice president and chief financial officer Gary Millerchip said that "about half of members" who fill up at a Costco gas station also make a purchase inside the warehouse. A standalone station breaks that link, at least geographically. Whether Costco can sustain the low-margin fuel model without the warehouse cross-sell is one of the open questions the Mission Viejo experiment will answer.
The retailer has been expanding warehouse locations across the U.S. and Canada, so the gas-only format is not a retreat from brick-and-mortar, it is an addition.
The per-gallon discount is only the starting line. Costco and its wholesale rivals offer credit cards and membership upgrades that push the effective price even lower.
The Costco Anywhere Visa Card by Citi carries no annual fee beyond the required membership. It pays 5% cash back on Costco gas purchases and 4% on other eligible gas and EV charging up to $7,000 in combined spending per year, then 1% after that. It also returns 2% on purchases at Costco and Costco.com. The regular APR runs 18.74% to 26.74% variable, a reminder that carrying a balance wipes out the rewards in a hurry.
Costco recently boosted gas rewards for its credit card holders, making the fuel-savings math even more favorable for members who pay their balance in full each month. The Executive Membership, at $130 per year, adds a 2% annual reward certificate on pre-tax purchases, capped at $1,250.
Costco is not the only wholesale club selling discounted fuel. Sam's Club, owned by Walmart, charges $50 for its basic Club membership and $110 for Plus. Its co-branded Sam's Club Mastercard earns 5% back in Sam's Cash on gas and EV charging on the first $6,000 per year, then 1%. The card has no annual fee but requires a Sam's Club membership. It comes with a $30 statement credit as a welcome bonus, and total Sam's Cash earned is capped at $5,000 per year.
BJ's Wholesale Club advertises that its members save an average of 20 cents per gallon. The basic BJ's Club membership runs $60 per year; the Club+ tier costs $120 and adds an extra 5 cents off per gallon. BJ's Fuel Saver program can knock 10 cents or more off per gallon, though the discount must be used within 30 days and applies up to 40 gallons or $99, whichever comes first.
The BJ's One+ Mastercard takes another 15 cents per gallon off at BJ's Gas, carries no annual fee (membership required), and has a regular APR of 19.99% to 28.49% variable.
Each program has its own caps, restrictions, and fine print. But the common thread is simple: wholesale-club gas stations consistently beat the posted price at traditional stations, and the credit-card layer amplifies the difference.
Broader forecasts suggest gas prices may drop significantly in 2026, which would be welcome news for American households. But even in a falling-price environment, the per-gallon spread between wholesale-club stations and street-corner competitors tends to persist. Costco, Sam's Club, and BJ's compete on volume and membership loyalty, not on spot-market timing.
For Southern California drivers paying close to six dollars a gallon, a 40-pump standalone Costco station that shaves half a dollar off every fill-up is not a curiosity. It is a line item in the household budget.
The Mission Viejo station will also test whether Costco can attract enough volume to justify the real estate without a warehouse anchoring foot traffic. Millerchip's earnings-call comment, that about half of gas customers also shop the warehouse, hints at the risk. Remove the warehouse, and you remove a significant revenue stream that subsidizes cheap fuel.
Still, Costco has been in the fueling business for more than 30 years. The company is not guessing. It is placing a calculated bet that membership-only gas, priced aggressively, can stand on its own.
Several questions remain unanswered. The exact opening date in June has not been announced. The precise street address in Mission Viejo has not been disclosed publicly in the available reporting. And whether Costco will roll the standalone model into other high-cost metro areas, or keep it limited to California and Hawaii, is still an open question.
What is not in question is the demand. Americans are tired of paying more at the pump than they have to. When a retailer offers a consistent, measurable discount and backs it with a 40-pump station built for throughput, people will show up.
In a country where government energy policy has spent years making fuel more expensive, the private sector keeps finding ways to give drivers a break. That is not a coincidence. That is the market doing what markets do when regulators get out of the way.
