What are the best times to go to Costco gas? ›

Gas stations can get busy (avoid weekends)

Avoid weekend fill-ups if you can. Buying gas on a weekend could be a nightmare, as waiting times could take hours. To avoid this, the best time to get gas at Costco is on weekdays between 10-11 in the morning.

For example, in Bakersfield, California, gas prices ranged from $4.99 per gallon at Costco competitor Sam's Club, up to $5.39 at 7-11 last year. Gas at Costco was among the cheapest options at $5.09 per gallon. That would be a savings of 30 cents per gallon at Costco compared to 7-11, or $4.20 per 14-gallon tank.

Generally speaking, buying gas at Costco is significantly cheaper than doing so at a traditional gas station. The typical driver can save more than $100 per year. Buying gas at Costco can justify a membership all by itself.

All major fuel retailers accept the Pay with GasBuddy card with the exception of the following brands: Exxon Mobil, BJs, Costco, Sam's Club, H-E-B, Select Walmart stations, Select Arco Stations. Is my personal information secure?

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.

Best Day of the Week

According to a GasBuddy petroleum analyst, Monday and Tuesday is when gas prices are typically at their cheapest. As the week goes on, prices steadily tend to rise while finally culminating in the highest price during the weekend.

While both Costco and Sam's Club offer unleaded, premium, and diesel fuels (here's how to know which you should be getting), only Costco offers Top Tier fuel. If you don't have a Costco membership, you can still find Top Tier gas at other stations. “Yes, Top Tier gas is worth the extra money,” CarFax reported.

Gasoline ​octane can vary by state, but at Costco, it's typically 87 octane for Regular and 91 octane for Premium Gasoline.

Good station operation and maintenance means the fuel is filtered and that contaminants, such as sediment and water, do not find their way into our members' vehicles. Costco fuel stations are well-maintained by our capable attendants so you may be confident that the fuel going into your car is clean.

Gas purchases, for example, do not earn you cash back as an Executive member. Neither do cigarette purchases or alcoholic beverage purchases in certain states. Additionally, Costco Shop Cards (Costco's version of a gift card) won't be eligible for cash back, and neither will postage stamps.

Where does Costco gas come from? ›

Where does Costco gasoline come from? The gasoline from you local Cosco comes from the same terminal as the rest of your local gas stations. The only difference is that is doesn't get the proprietary additive package added to it that you pay extra for from Shell or Chevron or whatever your local options are.

It's good for your car

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.

Can other people use my membership card? The Costco membership card is non-transferable, but there are several ways to share the experience with family and friends. Anyone with a card can bring up to two guests to the Warehouse during each visit. Keep in mind that purchasing items is exclusive to Costco members.

Costco warehouses and gas stations do not currently accept cards from any network other than Visa. This means Costco members shopping in-store cannot pay with American Express, Mastercard or Discover—nor any other non-Visa credit card.

Anyone can use a Costco Shop Card at the gas station, as it also serves as membership authorization for the pump.

Bottom Line

While you can't control the price of gas on a given day, you may be able to squeeze out a few extra nickels by filling up very early in the morning or late at night when the temperature is cooler. The effect of heating up gasoline can cause it to slightly expand, and you will get less fuel for your money.

But saving money at the pump doesn't just mean knowing where to fill up – it also helps to know when to fill up. 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.

“In general, though, the best time to shop at Costco is going to be when they first open on Mondays, Tuesdays and Wednesdays, as generally that's the least popular time for shoppers to be out,” Ramhold said.

Early in the morning when the temperature is the lowest. Fuel is sold by the gallon, but the density of fuel varies with temperature. A warm gallon of fuel will weigh less than a colder gallon of fuel.
