Costco Gas Near Me: The Warehouse Fuel Advantage
Costco runs 747 gas stations across the United States, sells Top Tier certified Kirkland Signature gasoline, and typically prices fuel 10 to 25 cents per gallon below nearby stations. If you are hunting for a Costco gas near you, the payoff is real: the company treats fuel as a traffic driver, not a profit center, selling gas at or near cost so members fill up and then walk inside to shop. Costco executives reported record fuel demand in 2026, with some stations needing multiple tanker deliveries per day.
The catch is that the pumps are for members only, and the stations can get very busy. Long lines are the most common complaint at Costco fuel islands, especially on weekends. The trick is to fill up when the warehouse itself is closed, since the gas stations open earlier and stay open later than the stores.
Costco Gas Prices: How Much Members Actually Save
Costco consistently undercuts surrounding stations. Analysts and member reports put the typical gap at 10 to 25 cents per gallon, though it varies by market and by day. Because Costco makes only a few cents per gallon on fuel, the savings are built into the business model rather than coming from a coupon or loyalty gimmick. For a driver filling a 15-gallon tank weekly, a 20-cent discount saves more than $150 a year, which alone covers the basic membership fee.
Prices do move with the market, so check current pump prices in the Costco app or on a price-tracking app before driving across town. Costco is even testing standalone fuel stations: a 40-pump Kirkland Signature Fuel station opened in Mission Viejo, California in 2026, the company’s largest fuel site to date. If saving on every gallon is the goal, our cheap gas near me guide compares the lowest-priced options wherever you drive.
Membership Rules at the Pump
You need an active Costco membership to buy gas. The pump asks for your membership card first, then a payment method. As of 2026, memberships run $65 per year for Gold Star and $130 per year for Executive. At the pump you can pay with any Visa credit card, a PIN-based debit card, or a Costco Shop Card. The Shop Card is the one exception to the membership rule: anyone holding a Costco Shop Card can buy fuel without being a member.
Executive members earn a 2 percent annual reward on qualifying Costco purchases, up to $1,250 per year, which can make the pricier tier pay for itself if you buy a lot of fuel and groceries. Check Costco’s current terms to confirm which purchases qualify for the reward.
Costco Gas Station Hours
Costco fuel stations are not 24-hour operations, but they stay open longer than the warehouses. A typical pattern is 6 a.m. to 10 p.m. Monday through Friday, with shorter hours on weekends, often 6 a.m. to 8:30 p.m. Saturday and 6 a.m. to 7:30 p.m. Sunday. Some locations open as early as 5:30 a.m. or even 4:30 a.m. Hours vary by location, so check your specific warehouse’s listing before heading out, especially on holidays.
The best time to fill up is early morning before the warehouse opens or late evening after the shopping rush. Midday Saturday is the worst time at most locations, with the longest lines of the week.
Kirkland Signature Fuel Quality
Costco gasoline is sold under the Kirkland Signature brand and is Top Tier certified, meeting the higher detergent standards backed by major automakers. That makes Costco one of the rare places where the cheapest gas in town is also among the cleanest-burning. High station volume helps too: tanks at busy Costco stations get refilled several times a day, which means fresher fuel and less time for sediment to settle.
Costco sells regular and premium unleaded gasoline at most fuel stations. Diesel is available too, but only at select locations, around 60 stations nationwide, and that diesel is also Top Tier certified.
