Costco Gas Foster City (2024)

FAQs

What brand of gasoline does Costco use? ›

Q: Where does Costco get its fuel? A: Costco buys fuel from major refineries and distributors in each area. All Kirkland Signature™ Fuel is guaranteed, just like the merchandise we sell inside the warehouse.

The data shows that Costco's prices aren't typically the absolute cheapest, but they're always significantly less expensive than the "average" price. This means you're more than likely getting a deal when you get gas from Costco versus another random gas station in your city.

Quality gas is important, yes, but so is price. Costco Gas Stations offer consistently low, member-exclusive prices. With the Costco app, you can check Costco gas prices on your phone. On the app, find your local warehouse to see hours of operation, gas prices and more warehouse details.

Plan your fueling around the quieter times, typically during the middle of the week and early in the morning. Additionally, members can consult the Costco app, which sometimes offers real-time updates on gas station wait times.

You'll know you're filling up with the good stuff if you spot a small green sticker on the pump that says “TOP TIER Detergent Gasoline.” As of early 2022, the following stations sold Top Tier gasoline in the U.S.: 76, ARCO, Aloha, Beacon, Breakaway, CITGO, Cenex, Chevron, Conoco, Costco Wholesale, CountryMark, ...

Gas is gas - the additives are different. Chevron by far has the best add pack, Costco uses a custom Lubrizol add pack that meets Top Tier specs.

The short answer is that unlike pretty much every other retail business that sells gasoline, Costco doesn't care about making money from its gas pumps. In fact, Costco typically sells its gas at a moderate loss. Why would Costco do this? It's not an act of charity.

The fact that gas is cheaper at Costco doesn't mean it's lower in quality. The company offers Kirkland Signature gasoline, which is formulated to improve vehicle performance and fuel economy. Costco says the gas also reduces emissions, making it better for the environment.

Costco gas typically saves you around $0.20 per gallon. If you fill up often enough, gas alone can pay for your membership. The number of times you need to visit depends on how much gas your tank holds.

You can save money on gas at Costco by virtue of the store's lower price per gallon. But you can also save money on gas by combining a grocery run and a fill-up. If you don't have to drive to a different gas station, you won't have to use gas to get there.

What percent back does Costco give you for gas? ›

You'll get 4% back on eligible gasoline purchases for the first $7,000 per year and then 1% thereafter.

So if you spend more than $3,250 per year at Costco (most people do), the executive membership pays for itself.

Buy Gas on Monday or Tuesday

Be strategic about the days you fill up at the pump. “For gas, Mondays and Tuesdays tend to be the cheapest days to fill up your tank as demand is lower at the beginning of the week,” Anderson said.

In general, gas prices tend to be lowest at the beginning of the week, on Monday and Tuesday, GasBuddy's lead petroleum analyst Patrick De Haan told Nexstar. As the week goes on, gas prices tend to rise until they reach their most expensive point on the weekend – especially on Friday and Saturday.

“Consumers see this as a customer-friendly convenience, but in truth, they help reduce congestion at the pumps, which allows more cars to pass through the pumps, which allows Costco to sell more gas,” says Bines. “It's a win-win, but only because it first benefits the consumer.”

It's just fuel from the same outlets as shell, BP and all the supermarkets. Fine to use. MrAverage said: Used Costco fuels exclusively for a few years (Costco round the corner), didn't have any issues with either.

Collaboratively introduced in 2004 by General Motors, BMW, Toyota, and Honda, TOP TIER™ Approved Gasoline and Diesel have become synonymous with exceptional fuel quality and engine care.

Conoco® fuel has 3 times more detergent additive than the minimum required by the EPA and 30% more than the TOP TIER^® Detergent Gasoline standard recommended by major car manufacturers.

Chevron with Techron cleans up grimy deposits that can interfere with fuel combustion - which can boost your miles per gallon. *In as little as 4,500 miles of driving, gasolines with Techron can remove up to 50% of harmful carbon deposits.
