Costco gas prices are some of the cheapest around, but how does it compare with other gas companies? Fuel prices vary by state and providers, so we’ll take a look at how Costco’s gas prices stack against other companies by looking at some examples.

In Florida, according to, Costco gas has a per-gallon price of $3.17, which is about the middle of the road because it’s certainly not the cheapest. The company that offers the most affordable gas price is Circle K, with $2.97 per gallon.

How Does Costco Keep Its Gas Prices Low?

Based on a report by CNN, Costco gas prices are typically 20 cents cheaper than the market average. The wholesale chain can afford to keep its fuel prices low due to the sheer volume of gas it sells. The busiest Costco locations can sell up to a jaw-dropping million gallons of fuel each month, while typical gas stations can only manage about 80,000 gallons.

With lower gas prices, Costco has relatively narrow profit margins from fuel sales. In fact, Costco reported that gas sales have a lower profit margin than the rest of its businesses. However, their gas stations provide Costco with an unparalleled advantage because they drive the sales of its warehouses.

To get gas from Costco, you need to be a member. People interested in saving at the pump usually sign up for a Costco membership. As a member, you need to drive all the way to a Costco to get gas. While you’re there next to the warehouse, you might as well pick up boxes of snacks, a large tub of mayo, or perhaps a new 4K TV.

The bottom line is lower gas prices increase membership signups and get people to the warehouses. With gas prices skyrocketing, we can only conclude that this model will continue to pay off for Costco.

Is Costco Gas Good Quality?

Due to the chain’s low gas prices, many people wonder about potential compromises, mainly fuel quality. Like many warehouse items, Costco gas is also a Kirkland Signature.

According to the promotional material, Kirkland Signature gas can improve performance, restore fuel economy, reduce emissions, and protect components from harmful deposits.

Costco fuel has been certified to meet the standards and stringent requirements of TOP TIER. Therefore, Costco fuel isn’t just known as affordable but boasts good quality as well.

Any Downsides to Pumping Your Gas at Costco?

Costco gas is reliably lower priced than nearby gas stations for many states. However, there are a few critical drawbacks to getting your gas at Costco that you should know:

Long Lines

Costco gas pumps are notoriously known for their long lines. In their busiest gas stations, people have reported waiting in line for as long as an hour to pump their vehicles. Time is money, and if you’re waiting that long each time you fill up, a few dollars in savings becomes harder to justify.

Requires Membership

Costco fuel stations are open to members only. Currently, signing up for a Costco membership will cost you an annual fee of $60. However, according to Kiplinger, the chain is on track to increase its memberships by $5 to $10.

If you become a member just for the fuel, you’re getting a kind of a lousy deal. With a 16-gallon fuel tank and savings of about 10 cents per gallon, you’ll need more than 37 fillups to cover the membership cost.

May Not Be Worth the Drive Time

Costco gas stations are only available near its warehouses, which means driving all the way there to pump gas. If you’re nowhere close to a Costco warehouse, it might be counterproductive to go on long drives just to get fuel. Again, this is especially true if you’re only a Costco member because of the gas.

Costco Gas Stations Don’t Accept Cash

First-time buyers are often surprised to find out that they can’t pay for gas using their credit cards or cash. Specifically, you can only use Visa cards to pay for gas or any other Costco products for that matter.

To use your cash, you’ll have to go the roundabout way of going into the warehouse and using cash to get a Costco cash card. It can be a huge inconvenience if you don’t have a card that belongs to the Visa network.

Costco Gas Prices [UPDATE 7/27/2023]

According to AAA, the national average gas price is now $3.714 per gallon. Over the last few months, gas prices have been coming up and down, but lately, they’ve been on an upward trajectory in the last few weeks. NBC News says that the current $3.714 per gallon has been the highest price since November last year.

Costco gas prices are notably affordable, leading to frequent long lines at their pumps. For example, in Huntington Beach, CA, the prices are $4.39 for regular and $4.59 for premium, while the Costco in Vallejo offers prices of $4.11 and $4.31 for regular and premium, respectively. Even in California, known for high gas prices, Costco remains a top company for lower gas prices.

If you can bear with the long queue times, Costco is certainly a great place to fill up on fuel.
