Sam's Club fuel is cheaper than most gas stations because members buy in bulk and the warehouse passes savings along

Sam's Club sells gasoline and diesel at its warehouse locations to members only. The price is typically 20 to 40 cents per gallon lower than nearby commercial gas stations, though the exact difference changes weekly based on crude oil prices and your region. You pump your own fuel at outdoor stations attached to the warehouse — there is no convenience store, no attendant, and no credit card reader at the pump itself.

To buy fuel, you need an active Sam's Club membership card. The membership itself costs money upfront, so the savings on fuel alone may or may not pay for the card depending on how much you drive. Sam's Club publishes its fuel price online and updates it daily, so you can check before you visit.

Key Takeaways

  • Sam's Club fuel costs 20 to 40 cents less per gallon than most gas stations, but you must be a member to buy any.
  • Membership costs between $45 and $110 per year depending on the tier you choose, so calculate whether your fuel savings will cover the fee.
  • You pay for fuel inside the warehouse or at the pump using your membership card, and you pump the gas yourself.
  • Sam's Club publishes fuel prices online daily, updated by region, so you can compare before driving to a location.
  • Not all Sam's Club locations have fuel stations — check the warehouse locator on the website to confirm your nearest location sells gas.

Membership tiers and what each one costs

Sam's Club offers two main membership levels: Gold Star and Plus. A Gold Star membership costs $45 per year and gives you access to the warehouse, fuel pumps, and basic discounts. A Plus membership costs $110 per year and includes everything Gold Star offers plus additional discounts on select items and services, a higher cash-back rate on Sam's Club purchases, and other perks like roadside information.

Both memberships are personal — they are tied to one person's card, though some warehouses allow household members to shop together if they are listed on the account. If you live with someone else and both want to shop separately, you may need two memberships. Sam's Club occasionally runs promotions that waive or reduce the membership fee for new members, so check the website before you sign up.

How fuel pricing works and where to find current prices

Sam's Club sets fuel prices based on wholesale crude oil costs, regional supply, and local competition. Because the warehouse buys fuel in massive volume, it can pass lower prices to members than independent gas stations can offer. The price you pay at the pump is the same price all members pay at that location on that day — there is no discount tier or loyalty program that makes fuel cheaper for some members than others.

You can see the current fuel price at any Sam's Club location on the company's website. Go to the warehouse locator, enter your zip code, and click on a location to see today's price for regular unleaded, premium, and diesel. Prices update once per day, usually in the morning. If you are comparing Sam's Club to a nearby Costco or Kroger fuel center, remember that each warehouse updates at different times, so the prices you see online may be a few hours old.

What happens when you arrive to pump fuel

Drive to the fuel station area outside the warehouse. You do not need to go inside first — the pumps are accessible from the parking lot. Swipe or insert your membership card at the pump to unlock it. The pump will display the available fuel grades: regular unleaded (usually the cheapest), mid-grade, premium, and diesel if the location offers it.

Select your grade, insert the nozzle into your vehicle's tank, and pump as you would at any gas station. The pump will stop automatically when your tank is full. You pay at the pump using your membership card — you cannot use a credit card or cash at the pump itself. If you prefer to pay inside the warehouse, you can do that too: go to the fuel desk, tell them your pump number, and pay with any method Sam's Club accepts (membership card, credit card, debit card, or cash).

Calculating whether membership pays for itself in fuel savings

To decide whether a Sam's Club membership is worth the cost, multiply the price difference between Sam's Club and your current gas station by how many gallons you buy per year. For example, if you save 30 cents per gallon and you buy 1,000 gallons per year, your annual savings is $300 — which easily covers a $45 Gold Star membership. If you buy 200 gallons per year, your savings is only $60, which does not cover the membership fee.

Most people drive between 12,000 and 15,000 miles per year. If your vehicle gets 25 miles per gallon, that is roughly 500 to 600 gallons per year. At 30 cents per gallon saved, that is $150 to $180 in fuel savings — enough to justify a Gold Star membership but not a Plus membership unless you also use the warehouse for groceries or other discounted items. Use the EPA's fuel economy tool to estimate your vehicle's actual mileage, then do the math for your own driving.

Not all Sam's Club locations have fuel stations

Sam's Club operates fuel stations at most of its warehouses, but not all. Newer locations and some urban warehouses do not have pumps. Before you drive to a location expecting fuel, check the warehouse locator on the Sam's Club website. Enter your zip code, click on a location, and look for the fuel pump icon. If it is not there, that warehouse does not sell fuel.

If your nearest Sam's Club does not have fuel, you can still buy fuel at a different location if you are willing to drive farther. Some members plan their shopping trips around a warehouse that has both fuel and the groceries they need, even if it is not the closest one. Others use Sam's Club for warehouse shopping and buy fuel elsewhere.

Frequently Asked Questions

Can I use someone else's membership card to buy fuel?

No. The membership card is tied to one person, and you must present that person's card at the pump. Sam's Club does not allow household members or friends to use another person's card to buy fuel, even if they are listed on the account. If you want to buy fuel regularly, you need your own membership.

What payment methods work at the fuel pump?

Your Sam's Club membership card is the only payment method that works directly at the pump. If you want to pay with a credit card, debit card, or cash, go inside the warehouse to the fuel desk, tell them your pump number, and pay there. You can also prepay at the fuel desk before you pump.

Does Sam's Club fuel have the same quality as name-brand gas stations?

Sam's Club fuel meets federal standards for gasoline and diesel, and it contains the same detergents required by the EPA. It is not a premium or top-tier fuel brand, so it may not have the extra cleaning additives that Shell, Chevron, or Mobil add. For most vehicles, the difference is not noticeable, but high-performance engines may run better on premium fuel.

What if I run out of gas between the pump and the exit?

This is rare because Sam's Club pumps are located very close to the parking lot exit. If it happens, stay in your vehicle, turn on your hazard lights, and call Sam's Club customer service or a roadside information service. Do not attempt to push the vehicle or refuel it yourself on the warehouse property.

Can I return to the pump if I did not get a receipt?

Yes. Your transaction is recorded on your membership card and your credit card or bank statement. If you need a receipt, go to the fuel desk inside the warehouse with your membership card and the approximate time you pumped fuel, and they can print one for you.
