Costco might be home to rotisserie chickens and bulk goods, but the company has also earned a reputation for being the best place to buy fuel.
At any given time, you can find gas prices significantly lower than the rest of the region just by shopping with Costco. But how does Costco sell gas so cheap, and what is the overall cost?
In this guide, I explain why Costco gas is so cheap. I also look at a few reasons to fill up at Costco and point out a few downsides you might not have thought about.
Why Is Costco Gas So Cheap?
Costco gas is cheap because of the volume they are selling, and it’s used to attract customers into the store to buy higher-margin items when becoming a customer. With Costco selling gasoline at an average of 20 cents a gallon below the regional average, it seems unusual that the company makes a profit.
Costco fuel tends to be even lower than Walmart and Sam’s Club in many regions, with averages hitting 20 cents lower than expected. However, an analysis of how much revenue these low prices bring the company shows why it’s a good marketing tactic.
When you fill up at Costco, you probably head into the store to grab a few things while you are there. While the company is happy for you to buy some snacks, a new shirt, and giant jars of pickles, the real hope is that you grab that new couch you see or upgrade your television.
Annually, Costco sells about $20 billion of fuel, making up about 10% of the total sales. While it’s a low-margin commodity, there’s no lack of volume happening at the pumps. In fact, one Costco location can easily sell a million gallons of fuel in a month, where the average gas station pumps out 80,000 gallons.
Additionally, Shell, Exxon and other notorious gas stations tend to be independently owned. Because of this structure, they can’t afford to lower prices to match Costco. These retailers need to make a decent amount of money on the fuel that’s being sold, unlike Costco, which can make it up in retail products.
RELATED: Which Gas Stations Have The Best Quality Gas? (Top 5 Best)
Benefits of Costco Fuel
1. Top Tier
One would think that Costco skimps on the quality to keep the prices low, but that’s not the case. As with all of the Kirkland products in the store, the gasoline is of the highest quality.
In fact, Costco uses top tier fuel, which means it meets a certain standard. It contains special additives that clean the engine and reduce buildup. Top tier fuel is known for improving engine performance, maximizing fuel economy, and protecting the internal components of the motor.
2. Check Prices in App
Most people agree that getting high-quality gas is important, but no one wants to pay more than necessary. While everyone knows Costco sells some of the lowest-price gas, you want to be able to compare pricing.
Thankfully, the Costco app allows you to do that. Before you make a trip to Costco, you can check the prices to see how they compare. You can also get other important information, such as the hours of the store.
3. Safety Attendants
When you visit a regular gas station, there’s nobody standing by, ensuring your safety. However, that’s exactly what Costco provides to its customers every day. The Costco safety-certified attendants are trained to run the show.
They can offer assistance if you are having trouble pumping fuel, and they also keep the area clean. Most importantly, they understand how to run the fuel station, so it complies with environmental and safety regulations. This peace of mind is worth its weight in gold.
Costco doesn’t just offer top tier gasoline, but also has diesel at the pumps. If you drive a pickup, you can save money on your fuel as well. Kirkland Signature diesel is just as high quality as the gasoline.
Costco assures that the diesel fuel prevents wear to the engine and improves combustion for an easier start-up. It is also created to clean out the engine and protect the fuel system.
On top of that, Costco diesel is designed to ensure that the injectors operate cleanly. That’s why it has also earned the prestigious status of Top Tier.
There are many perks to shopping with Costco in general, but having the Anywhere Visa Card by Citi makes shopping with this store even better. This credit card offers 2% back on all Costco and Costco.com purchases.
What makes it truly special is what is received when you use it for fuel. Not only can you take advantage of the super low gas prices, but this card also gives you 4% cashback. You can earn up to $7,000 each year.
Downsides of Costco Fuel
1. Long Lines
If you’ve ever been to the Costco fuel pump during rush hour, you know how long the lines can get. Sometimes, all of the cars won’t even fit into the area.
If you are in a hurry, the savings might not pay off for you, especially if waiting might make you late for work. Additionally, you won’t want to wait longer than necessary if the gas light is on and you’re about to run out of fuel.
2. No Cash
While the majority of people rely on paying with plastic these days, there are still some that prefer cash. Costco only accepts debit cards, Visa credit cards, and Costco cash cards. You won’t be able to pay cash at these pumps.
If you are someone who needs to walk cash inside to the attendant and watch the gas pump rise slowly at the end, getting fuel at Costco won’t make you happy. You can head to the local gas station or run inside and buy a Costco cash card instead.
Costco locations don’t tend to be situated close to one another. These stores don’t oversaturate the market like Walmart and Sam’s Club.
Because of this, there may not be a Costco gas station close to you. Is it worth driving an hour to save 20 cents a gallon? Probably not – especially if your vehicle isn’t fuel-efficient. For this reason, you might only fill up at the Costco gas station when you are already in the area.
