Costco Gas Station in Baltimore: Membership-Only Fuel Below Market Rate

Costco's gas station sits in the warehouse parking lot on Annapolis Road in Glen Burnie, open exclusively to members and offering fuel priced consistently 20 to 40 cents per gallon below Baltimore-area retail averages, though the membership fee and modest fuel volume caps mean savings accrue only for regular drivers.

What Costco Gas Actually Is

This is not a traditional gas station. It operates as a member benefit tied to Costco warehouse membership, with pumps located in the parking lot adjacent to the Glen Burnie warehouse. The station accepts only Costco membership cards and Costco credit cards at the pump; non-members cannot purchase fuel here. Unlike full-service stations, there is no convenience store, car wash, or repair bay attached. You pump your own fuel and leave. The operation exists to reward high-volume members and keep them in the Costco ecosystem rather than to compete with Shell, Wawa, or Sunoco on convenience or accessibility.

Fuel Pricing and Limits

Costco publishes pump prices daily on its website and app, and pricing typically tracks 20 to 40 cents below the Baltimore average for regular unleaded, depending on global crude prices. Verification of current pricing is essential; prices shift weekly. The station does enforce a fuel limit of 35 gallons per visit for members in good standing, though this rarely affects personal vehicle owners. Diesel is available at a similar discount. Credit card rewards (typically 2 percent cash back for Costco Executive members on fuel purchases) further reduce effective cost but require using a Costco-branded card.

How It Compares to Baltimore-Area Options

Traditional gas stations like Sunoco, Shell, and Wawa charge full retail and offer convenience: open 24 hours, located throughout the city and suburbs, stocked with snacks and drinks. Costco gas saves money only if you hold a membership (Gold at $65 annual, Executive at $130 annual) and visit regularly. A driver using 400 gallons per year at a 30-cent per-gallon advantage saves $120 in fuel cost, which exceeds the Gold membership fee but requires discipline. SAM'S Club operates a similar model with comparable pricing. Forget Costco gas if you drive infrequently, live far from Glen Burnie, or prefer spontaneous fill-ups; choose it if you commute regularly and value predictable, low per-gallon cost over convenience.

Who This Suits and Who It Doesn't

This station serves Costco members who commute 10+ miles daily, live or work near Glen Burnie, and fill up weekly or biweekly. The savings compound for households with multiple vehicles. It does not suit casual drivers, those without nearby Costco membership, people on tight parking schedules, or anyone who refuels reactively. A single fill-up to test the station is pointless; the value emerges only over months.

The First Visit

Arrive with your Costco membership card. The pumps sit at the south end of the Annapolis Road lot, clearly marked. Tap your card at the pump, select grade and payment method (membership card or linked Costco credit card), and fill up. No attendant, no transaction inside the warehouse. The pump network is straightforward but not faster than a standard station. If you do not yet hold membership, you can purchase a Gold or Executive card at the warehouse customer service desk or online before your first fuel visit.

Hours, Parking, and Logistics

The Costco gas station on Annapolis Road operates during warehouse hours, typically Monday through Friday 10 a.m. to 8:30 p.m., Saturday 9:30 a.m. to 8 p.m., and Sunday 10 a.m. to 6 p.m., though these vary seasonally and occasionally shift. Confirm hours on the Costco website or app before driving specifically for fuel. Parking is ample; the lot services the warehouse and gas pumps together. The station is located at 6500 Annapolis Road, Glen Burnie, Maryland 21225. There is no competing Costco gas location closer to central Baltimore.

Costco gas in Baltimore rewards committed members with genuine savings on a staple expense, but only if membership cost and inconvenient location align with your driving habits. For occasional drivers or city residents without easy access to Glen Burnie, standard retail stations remain the practical choice.
