Costco Gas Station Hours: What Time Do They Open and Close?

Knowing when your local Costco gas station opens — and closes — can save you a wasted trip. Costco gas stations keep different hours than the warehouse itself: they often open earlier in the morning and sometimes close later in the evening, so you cannot assume the gas pumps follow the same schedule as the store. This guide covers the national default schedule, why hours vary, and how to find the exact times for your station.

Typical Weekday Hours

Based on verified data from over 150 Costco gas stations across the United States, the most common weekday schedule is 6:00 AM to 10:00 PM, Monday through Friday. Saturday hours typically mirror weekday hours, with most stations running 6:00 AM to 10:00 PM as well. These hours apply to the gas station pumps — the adjacent warehouse may close earlier, often between 8:30 and 9:00 PM.

Hours can vary by as much as 90 minutes depending on location. Suburban stations in busy markets like California and Texas tend to stay open until 9:30 or 10:00 PM, while some smaller-market locations may close as early as 8:30 PM.

Sunday Hours

Sundays are shorter at most Costco gas stations. The most common Sunday schedule is 7:00 AM to 9:00 PM, giving you two fewer hours on each end compared to a weekday. Some locations close at 7:00 PM on Sundays, so it is worth checking before making a late trip. Sunday hours are set by each individual warehouse manager, so variation is more common on Sundays than on weekdays.

Why Gas Station Hours Differ from the Warehouse

Costco gas stations are physically separate from the warehouse, so they operate on their own schedule. In many locations, the gas station opens before the warehouse doors open — this allows members to fill up on their way to work without needing to enter the store. In some markets, the station also stays open briefly after the warehouse closes, letting members stop by on the way home from an evening errand.

Gas station hours are set at the warehouse level, so there is no single corporate schedule that applies everywhere. Local management adjusts hours based on traffic patterns, staff availability, and seasonal demand.

Holiday Hours and Closures

Costco gas stations are closed on four holidays every year: New Year's Day, Easter Sunday, Thanksgiving, and Christmas Day. On these days the entire Costco campus — warehouse and gas station — is shut down, with no exceptions reported across the national chain.

On other holidays like Memorial Day, Independence Day, and Labor Day, individual warehouses decide whether to operate with reduced hours or close entirely. Gas stations typically follow whatever the warehouse does for that day. The safest approach for a holiday visit is to call your local warehouse or check the Costco gas holiday hours schedule before making the trip.

Seasonal Changes

Some Costco locations adjust hours seasonally. Stores in areas with significant summer tourism may extend hours during peak season, while locations in college towns sometimes reduce hours during low-demand periods. Daylight saving time transitions occasionally cause a temporary one-hour shift in posted hours. If hours seem off on the first weekend of November or March, a DST adjustment is usually the explanation.

How to Find Your Station's Exact Hours

The most reliable way to get hours for a specific station is to search for it directly on this site. Each station page shows the verified weekly schedule — Sunday through Saturday — along with an "Open Now" or "Closed" indicator based on the current time. Where hours have not yet been independently verified, the page notes this clearly and provides a link to report the hours you observe.
