Does Costco Really Have the Lowest Gas Prices? Yes, Costco really does have some of the lowest gas prices in the country. Members save 30 to 63 cents per gallon compared to nearby gas stations. That’s real money back in your pocket every time you fill up.
But how does Costco keep prices so low? And is a membership worth it just for gas? Let’s break it down.
How Much Cheaper Is Costco Gas?
Costco gas prices typically run 30 to 63 cents below what you’d pay at Shell, Chevron, or other major brands. In high-price states like California, the savings can reach 50+ cents per gallon.
For a 15-gallon tank, that’s $4.50 to $9.50 saved per fill-up. Fill up weekly, and you could save $200 to $500 per year. Check our Costco gas station locator to find current prices near you.
Why Is Costco Gas So Cheap?
Costco uses a different business model than regular gas stations. They sell fuel at near break-even prices to attract members into their warehouses. The membership fees cover their costs, not high gas markups.
This strategy works. In April 2025, Costco reported two of their highest gallon sales weeks ever after extending gas station hours earlier in the year.
Is Costco Gas Good Quality?
Absolutely. Costco’s Kirkland Signature gasoline is TOP TIER certified. This means it contains more cleaning additives than the EPA requires. These additives keep your engine clean and running smoothly.
Major automakers recommend TOP TIER fuel. Costco gas meets the same quality standards as Shell, Chevron, and other premium brands. Learn more about how Costco gas compares to other brands.
Is a Costco Membership Worth It for Gas?
A Gold Star membership costs $65 per year. If you save 40 cents per gallon and buy 15 gallons weekly, you’d save about $312 annually. That’s nearly 5 times the membership cost in gas savings alone.
The Executive membership ($130/year) earns 2% cash back on Costco purchases. Pair this with the Costco Visa card’s 4% gas cashback, and your savings grow even more. See our full breakdown on whether Costco gas is worth the wait.
What About Wait Times?
Long lines are the main downside. Peak hours on weekends can mean 20-30 minute waits. However, visiting during off-peak times solves this problem.
Best times to go: early mornings (6-7 AM) or right after the warehouse closes when pumps stay open. Most stations now operate 6 AM to 10 PM weekdays. Find the least busy times at your local station.
The Bottom Line
Costco consistently offers the cheapest gas prices among major retailers. The fuel is high quality, and membership pays for itself quickly through gas savings. Check today’s Costco gas prices at 600+ locations on our tracker.
