Filling up at Costco has always meant a trip to the warehouse. Not anymore. The retailer has opened what it describes as its first standalone gas station in the U.S. — no warehouse, no food court, just fuel pumps — off Interstate 5 at Oso Parkway in Mission Viejo, in Orange County. ## A cheaper pump in a pricey market The station opened with regular unleaded at $4.79 a gallon, a figure that stood out against a punishing regional backdrop, [ABC7 reported](https://abc7.com/post/costcos-first-standalone-gas-station-opens-orange-county-california-tax-increase-looms/19392512/). At the time, Orange County drivers were paying about $5.35 a gallon on average and Los Angeles County drivers about $5.48 — both well over a dollar above the national average. One shopper told ABC7 the Costco price ran "80 cents to a dollar" cheaper than nearby stations. The roughly 40-pump station is one of the larger fuel operations in the area. Costco has long run its gas business on thin margins, treating cheap fuel as a perk that drives membership rather than a profit center in itself. The company has not said publicly whether it plans to expand the warehouse-free format; it was also not confirmed whether a membership is required to fuel up at the standalone site. ## The July 1 tax clock The opening lands just before California's annual fuel-tax adjustment. Under [Senate Bill 1](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201720180SB1), the 2017 law that funds road repairs, the state's gasoline excise tax rises automatically each July 1 in step with inflation. ABC7 reported that the rate is set to increase by about 2.2 cents a gallon this year, to roughly 63.4 cents — a figure the Herald could not independently confirm with the state tax agency before publication, though the annual SB 1 adjustment itself is set in statute. California already carries some of the highest fuel taxes in the country, layered atop federal taxes and the costs of the state's cap-and-trade program — a stack of charges that keeps California pump prices well above most of the nation's. ## What it means for drivers A 2.2-cent increase works out to roughly 33 cents more on a 15-gallon fill — modest on its own, but compounding over a year of commuting. For budget-minded Orange County drivers, Costco's no-frills station arrives at a useful moment. Whether Mission Viejo becomes a template for the retailer or stays a one-off, it is a sign that one of America's best-known stores believes its fuel brand can stand on its own — stripped of everything else that makes a Costco run a Costco run. ## Sources - [Costco's first standalone gas station opens in Orange County as California tax increase looms](https://abc7.com/post/costcos-first-standalone-gas-station-opens-orange-county-california-tax-increase-looms/19392512/) - [Senate Bill 1 (2017), Road Repair and Accountability Act](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201720180SB1)
