What is Costco Gas?

Costco gas refers to the fuel provided by the American warehouse club chain Costco. This gas is different from other gas brands in several ways.

First, Costco guarantees the highest quality for its fuel, which means that your vehicle's engine will be in good shape if you fill it frequently with gas from Costco. Second, Costco's gas prices are very low compared to those of competitors.

Additionally, the fuel is formulated using powerful deposit control additives. They allow your vehicle to run smoothly while cleaning the engine simultaneously.

Additionally, Costco claims that their gas also reduces pre-existing deposit buildups on different components of your engine. Here are some other benefits of Costco gas:

  • Better Performance: Costco gaso is formulated to decrease the level of deposit buildups in your engine.
  • Reduced Maintenance Costs: With regular Costco gas usage, maintenance costs are reduced.
  • Lower Emissions: Costco gas also has higher octane ratings compared to regular gasoline. According to some studies, using fuel with higher octane rating results in a reduction of pollutants released into the environment by your vehicle's engine.
  • Reputable Brand: Costco is a well-known and reputable company offering high-quality products and services for decades.

How Much Does Costco Gasoline Cost?

Is Costco gas cheaper? Costco gas costs much lower than its competitors, although the price of Kirkland Signature at the retailer may be different, depending on several factors that are not under Costco’s control.

Previous reports have shown that Costco gas prices are nearly 10 cents cheaperper gallon as compared to other providers. Costco gas stations are some of the cheapest places to buy gas in almost every state.

Why is Costco Fuel Cheaper?

There are mainly two reasons for Costco beating its competition in terms of pricing, but keep in mind that this does not include the quality of Costco gasoline.

Firstly, Costco knows it has a huge number of loyal customers, and the company does not want to lose them. People who come to Costco know they’ll find everything they need under the same roof.

So, it makes sense that the retailer wants to offer them gas for lower prices, too, since that is what Costco is known for.

Secondly, most Costco gas stations are close to the company’s warehouses. People who come to the gas stations to fill up their tanks are likely to go to the stores too and spend money inside as well as outside.

In this way, selling gas at a lower price does not put the company in a loss.

Instead, Costco’s strategic placement of its stores and lower prices actually help the company bag more sales and profits.

Is Costco Gas Good?

Yes, Costco gas is good. Costco's stable of gasoline is primarily composed of its own Kirkland Signature brand, which consists primarily of three grades - 87, 89, and 91 octanes. A smattering of other brands is available at select locations as well, including BP, Exxon Mobil, and Shell.

Gas stations that sell their own branded fuel often have the best prices since they're cutting out the middle man (i.e., the station that buys wholesale fuel in bulk and then sells it to customers at a markup).

What to Know Before Buying Costco Gas?

The first important point to understand is that Costco gas stations are for members only. If you are not a Costco member, you can save money at Safeway gas stations. Here are some things you should know before you purchase gas from the retailer.

Check Gas Prices Beforehand

In most Costco locations, you will see the gas prices displayed at the food court or the warehouse club's entrance. But it's still better to check the gas prices at Costco for today at home using GasBuddy or a similar app.

The benefit of knowing the gas prices beforehand are:

  • No Useless Driving: You'll only drive to your nearest Costco if you know they're offering a low gas price. Otherwise, there's no need to drive an extra mile to get cheaper gas while spending the money you're saving on the gas to travel that extra mile.
  • Peace of Mind: You'll know if this is the right Costco to visit for your vehicle that requires mid-grade or premium fuel. Also, if you're looking for a specific grade of gas, then you can find which stalls have what you're looking for without driving around aimlessly first.

Leave the Middle Lane Empty

When you go to a Costco location, you'll notice that there's a middle lane too.

Make sure you're not blocking everyone's way by leaving your car in the middle lane. What is the purpose of this lane anyway?

Well, Costco locations are designed to be convenient for everyone. Normally, when you go to a gas station, there are two pumps in the same lane.

Sometimes, it so happens that the car in the front pump leaves first. That's when you'd have to make your way to the pump in the front by taking over the car in front of you.

A middle lane gives you enough space to go to the front pump. That's why you should always leave this lane empty unless you're using it to reach the front pump.

Fill Your Tank on the Right Day

When you pull up to a Costco location, you'll find a huge queue of cars waiting to fill up at their gas pumps during the weekends. But surveys show that the price of gas tends to go lower on a Monday or a Tuesday.

You are also less likely to experience any traffic if you go early in the morning. During this time, the gas stations are open, but the warehouse clubs are closed.

Due to this, there's less traffic at the location. Check the timings for your nearest location on Costco's website.

Use Costco Anywhere Visa Card

Costco's Anywhere Visa Card by Citi is extremely handy for those looking to save on gas at the pump.

Gas prices are always lower if you use the card as a form of payment. In addition to saving money, there's also the option of earning points for free food and products from Costco itself.

If you are a rideshare driver or a delivery driver, you can get 2% cash back on your gas expenses using Nearside.

No Worries About the Tank Side

When you typically go to a gas station, you want to make sure your car is parked the right way for the gas nozzle to be in line with your car.

However, this is not a concern at Costco since the company has long pump hoses. You can take them around your car to fill gas from any side.

Costco Gas Station Operation

If it's your first time buying gas from Costco, you must have some questions about who can buy gas from the company and how to pay for it. Here are the different aspects of how a Costco station operates.

  • Who Can Buy: You can only buy Costco gas if you have a membership card. The only exception to this rule is that Costco Shop Card users can also buy top tier gas from Costco.
  • One-Way Traffic: When you pull up to a Costco station, one of the first things you'll notice is that the traffic only flows from one side. That's because the gas stations have extra long pump hoses. Thus, you can fill your fuel tank from any side without changing the side of the vehicle.
  • Payment: All Costco stations are self-serve, which means there will be no one to assist you. The stations have pay-at-the-pump technology. Costco accepts most PIN debit cards, Costco Shop Cards, and Visa cards.
  • Costco Shop Cards: You can buy these cards using checks or cash from the warehouse next to the gas station. For this, you need help from an attendant who will authorize the pump. After that, you can recharge this card whenever required.

Costco Fuel Quality and Types

Now that you know how Costco gas stations work, it's time to learn about the quality of fuel you get from these stations.

Costco gasoline is undoubtedly high-quality because the company focuses on two major aspects: station maintenance and deposit control additives.

DCAs refer to the type of additives that are added to your fuel to prevent corrosion. This helps improve the quality of your engine and prevent it from potentially stalling out later on.

DCAs are designed to better your fuel and engine.

You can also rest assured that the company will only use the best fuel for their customers. It follows stringent standards as well as federal regulations to ensure you get nothing but top-notch quality every time.

Costco also takes care of its pumps by focusing on cleaning them regularly. The cleanliness of these pumps ensures you'll get the best possible gas-pumping experience every time.

Here are some station maintenance steps taken by Costco:

  • All debris and particles on a Costco station that is bigger in size than 10 microns are caught by fuel filters. In doing so, Costco ensures the purity of its fuel, keeping it safe from contamination.
  • Costco's attendants check the flow rate of the nozzle from time to time to ensure the freshness of the filters. If the flow rate of the gas is lower than 8 gallons a minute, the company changes the filter.
  • Costco has ethanol-compatible filters that catch water, sediment, and water mixtures.
  • The company also has electronic sensors that are always monitoring the gas station's storage tanks for the presence of water.
  • More importantly, Costco physically inspects the tanks every week to rule out the chance of any contaminants affecting the fuel quality.
