Costco Gas is known for competitive fuel prices, convenient warehouse locations, and Kirkland Signature Gasoline that meets TOP TIER™ performance standards. Local prices and operating times vary by station, so the most reliable way to check Costco Gas prices today is Costco’s fuel locator. Most stations operate from early morning into the evening, with many open around 6:00 AM to 10:00 PM on weekdays.
Costco Gas Price Today in My Area
There is no single nationwide Costco gas price today because fuel prices are set locally and can differ considerably between warehouses. Costco’s official fuel locator lets members select a warehouse and view its current fuel prices, station hours, and holiday closures. Costco also notes that online prices are updated frequently but may not exactly match the price displayed at the pump when you purchase fuel.
For example, Costco’s current warehouse listings show different local prices: Richmond, California lists Regular at $5.24 and Premium at $5.79, while Richmond, Texas has a different local schedule and pricing.
That difference is why a national average should not be treated as your actual Costco fuel price.
How to check your local price
Open Costco’s fuel locator, enter your city, state, or ZIP code, and select the warehouse you plan to visit. The location page can provide the station’s fuel prices and operating hours.
If you are comparing stations before leaving home, check the price shortly before your trip because fuel pricing can change.
Costco Gas Hours
Costco Gas hours vary by warehouse, but many U.S. stations follow a schedule close to:
| Day | Common Gas Station Hours |
|---|---|
| Monday–Friday | 6:00 AM–10:00 PM |
| Saturday | 6:00 AM–8:30 PM |
| Sunday | 6:00 AM–7:30 PM |
These are common hours rather than a universal Costco schedule. Individual stations can open earlier, close later, or operate on a different timetable. For example, Costco’s Richmond, California warehouse lists gas hours of 6:00 AM–10:00 PM Monday through Friday, 6:00 AM–8:30 PM Saturday, and 6:00 AM–8:00 PM Sunday.
Costco specifically advises customers to use its warehouse locator because warehouse and service hours can vary by location, including gas stations.
Holiday schedules can also change. A station that normally operates late may have adjusted hours or a closure on a major holiday.
Costco Gas Near Me
To find Costco gas near me, use Costco’s official warehouse locator rather than relying only on a general map result. Search by ZIP code, city, or state and select a nearby warehouse with a Gas Station listed under its services.
The location page can show more than just the address. Depending on the warehouse, you can find:
- Current fuel prices
- Gas station hours
- Regular and Premium fuel
- Diesel availability
- Holiday closures
- Warehouse services
- Phone numbers
This is particularly useful when two Costco warehouses are within driving distance because their fuel prices and station hours may not be identical.
Lowest Gas Price at Costco Today
The lowest gas price at Costco today depends on your region. Costco does not publish one price that applies to every station because fuel pricing is localized.
When comparing nearby Costco locations, compare the same grade of fuel. A Regular price at one station should be compared with Regular at another, while Premium should be compared with Premium.
The price displayed online is also not a guarantee of the final pump price. Costco warns that its location prices are updated frequently and may not reflect the exact price at the pump at the moment of purchase.
A practical comparison is:
Fuel cost = gallons purchased × local price per gallon
For example, if your vehicle takes 15 gallons, a 20-cent-per-gallon difference represents a $3 difference on that fill-up. Frequent drivers can see a larger annual effect from small price differences.
Costco’s value also depends on membership cost, driving distance, vehicle fuel requirements, and how frequently you shop at the warehouse.
Costco Gas Octane Rating
Costco typically sells 87-octane Regular gasoline and 91-octane Premium gasoline, although octane availability can vary by state and location. Costco recommends using the octane grade specified by your vehicle manufacturer.
The important distinction is that octane and fuel quality are not the same thing.
Octane measures a gasoline’s resistance to engine knock. A higher number does not automatically mean that every vehicle will perform better on it. If your owner’s manual calls for Regular 87, paying extra for Premium generally is not necessary simply because the octane number is higher.
If your vehicle specifically requires or recommends Premium, use the grade appropriate for that engine.
Costco states that its fuel meets TOP TIER™ performance standards, while its gasoline also uses deposit-control additives designed to help clean and protect fuel-system components.
Premium Costco Gas
Premium Costco gas is typically 91 octane in the United States, although fuel specifications can vary by state.
Premium fuel is primarily relevant for vehicles whose manufacturers specify or recommend higher-octane gasoline. Before choosing it, check the fuel requirement printed in your owner’s manual, fuel door, or manufacturer’s specifications.
Costco describes its Premium gasoline as part of the Kirkland Signature Fuel range. Its fuel formulation contains deposit-control additives intended to reduce deposits on components such as intake valves and fuel injectors.
The higher price of Premium therefore should be considered alongside the requirements of your vehicle, rather than treated as an automatic upgrade for every car.
Costco Gasoline Supplier
Costco does not rely on one nationwide gasoline supplier. According to Costco, it purchases fuel from major refineries and distributors in each area.
This explains why the source refinery or distributor can differ between regions while the gasoline is sold under the Kirkland Signature Fuel name.
The brand is therefore more important than assuming that every gallon comes from one particular oil company. Costco maintains its own fuel specifications and quality requirements, and the company says its gasoline is certified to meet TOP TIER™ performance standards.
Costco also says its stations use filtration systems and conduct regular checks intended to control contaminants such as sediment and water.
Costco Gas Quality and Review
A major reason drivers choose Costco is the combination of fuel quality and price. Costco identifies its gasoline as Kirkland Signature Fuel and says it is formulated with deposit-control additives that help clean fuel-system components and reduce future deposit buildup.
Costco’s fuel is also certified to meet TOP TIER™ performance standards. Costco says its gasoline has been tested in laboratories and is formulated to address deposits affecting fuel injectors and intake components.
From a buyer’s perspective, the strongest part of the Costco fuel proposition is not simply the word “Premium” or the Kirkland label. It is the combination of:
recognized fuel standards + detergent additives + station maintenance + competitive local pricing.
Actual savings still depend on the price at your particular warehouse.
Costco also says its stations are maintained with filtration and monitoring procedures, including checks for water and contamination.
Is Costco Gas Worth It?
For many Costco members, the answer can be yes, particularly when a nearby station consistently offers a competitive price.
The value is strongest when you already have a Costco membership and the fuel station is convenient. Driving several miles out of your way to save a few cents per gallon can reduce or eliminate the financial benefit.
Costco membership is also required for most fuel purchases. Costco states that the fuel station is open to members, with an exception for customers using prepaid Costco Shop Cards.
The calculation is simple:
Your real savings = fuel savings − extra driving cost − membership cost attributable to fuel use.
For someone who regularly fills a large tank, drives substantial mileage, and lives close to Costco, the savings can accumulate. For an occasional driver with a small tank, the difference may be less meaningful.
Costco Gas Payment Options
Costco fuel stations use self-service, pay-at-the-pump technology. Costco says accepted payment methods include Visa cards, most PIN debit cards, and prepaid Costco Shop Cards, although payment rules can vary under state law. Oregon and New Jersey are exceptions because their laws require full-service fueling.
Your active Costco membership card is used to verify eligibility at the pump. After membership verification, you can select your fuel grade and complete payment.
Because payment options can change, checking the station or Costco’s current fuel information is sensible if you plan to use an unfamiliar payment method.
Costco Gas in Richmond
The search term Costco Gas Richmond can refer to more than one city, so the exact station matters.
For Richmond, California, Costco’s warehouse at 4801 Central Avenue currently lists its Gas Station hours as:
| Day | Richmond, CA Gas Hours |
|---|---|
| Monday–Friday | 6:00 AM–10:00 PM |
| Saturday | 6:00 AM–8:30 PM |
| Sunday | 6:00 AM–8:00 PM |
The location currently lists Regular at $5.24 and Premium at $5.79, but Costco cautions that displayed prices may not match the pump price at the time of purchase.
For Richmond, Texas, the Costco warehouse at 11125 W Grand Parkway S lists gas hours of 6:00 AM–10:00 PM Monday through Friday, 6:00 AM–8:30 PM Saturday, and 6:00 AM–7:30 PM Sunday.
This is a good example of why a city name alone is not enough when checking fuel information.
Costco Gasoline vs. Regular Gas Stations
Costco’s main advantage is its member-oriented pricing combined with Kirkland Signature Fuel. The gasoline itself is required to meet Costco’s fuel specifications, and Costco states that its fuel is certified to meet TOP TIER™ standards.
A nearby independent station can still be the better choice if it offers a lower price, is substantially closer, or has more convenient hours.
Fuel quality should also be assessed by standards and specifications rather than by the retailer’s name alone. Costco’s published fuel information provides details about its additives, filtration, testing, and TOP TIER certification, giving customers a clearer basis for comparison.
Costco Gas Holiday Hours
Costco fuel stations can have different holiday schedules from their ordinary weekly hours. Costco’s warehouse locator displays adjusted holiday hours and closures for individual locations.
Before making a special trip on Thanksgiving, Christmas, New Year’s Day, Labor Day, or another major holiday, verify the specific station rather than relying on its normal schedule.
This is particularly important because fuel stations can have service hours that differ from the main warehouse.

Final Thoughts
Costco Gas combines locally competitive fuel pricing with Kirkland Signature Fuel, TOP TIER certification, deposit-control additives, and a large network of warehouse-based stations.
The most useful information is always local: today’s price, today’s gas hours, fuel grade, and holiday schedule can differ from one Costco to another. Costco’s official fuel locator is therefore the best starting point before filling up.
For drivers who already shop at Costco and have a convenient station nearby, the combination of fuel quality and potential savings can make Costco a compelling choice. Just remember to use the octane recommended by your vehicle, compare the actual local pump price, and verify station hours before making the tri
