  • Costco is well-known for their great prices on a wide range of everyday items, gas included.
  • So, if you wanted to top up your tank at a reasonable cost, you might want to go to Costco. However, before you decide whether Costco gas actually works well for your needs,

    This is what I discovered after doing a lot of research.

    Is Costco Gas Good In 2022?

    Kirkland Signature gas from Costco, a Costco brand, is of excellent quality. It’s a “Top Tier” gasoline. That means that it is well above US government additives. Additionally, Costco sells gas at several cents less per gallon than their average competitors.

    How much is high-quality gasoline at Costco worth? What is the reason for such low gas prices at Costco?

    I’ve got everything you need to know right here, including costs, comparisons, drawbacks, and other important information.

    What is the Costco Gas Price?

    As with all other gas prices, the exact cost of the Kirkland Signature gas sold at Costco will vary depending on several factors beyond the retailer’s control.

    Costco can maintain lower prices than any other gas station, no matter how much they fluctuate.

    Costco’s gasoline costs on average about 21 cents more per gallon, according to a 2018 study.

    Others have claimed that the difference in price is less than 10 to 15 cents. The price of fill-ups can be quite high and could lead to impressive savings.

    Why is Costco Gas so Cheap?

    Costco is able to keep gas prices at such a low price because they charge a membership fee. Costco Kirkland Signature gas can only be purchased by Costco members.

    A personal membership can cost between $60-$120 per year depending on which benefits you are interested in.

    The price of membership accounts for around 75% of Costco’s profits, which allows the chain to keep prices low on everything from gasoline to groceries.

    The membership is not worth the cost unless your vehicle fills up regularly at Costco.

    Costco will require that you refuel 35 to 35 times each year in order for the membership to be worth its cost. If you are only using your Costco membership to purchase fuel, this would make it quite costly.

  • Costco Gas Vs Shell, Mobil, Texaco, Chevron, & Exxon
  • According to some Reddit threads, Costco gas is essentially the same quality as many gas companies, including Shell, Mobil, Texaco, Chevron, and Exxon.

    Additionally, some Reddit users believe Costco buys their gas from these very refineries and renames it under their own Kirkland brand.

    The only real difference between Costco gas and, say, Shell is that Costco adds fuel additives on site (to save money), as opposed to the refinery fuel rack.

    Additionally, Costco gas also meets the same US government additive requirements as Mobil, Texaco, and Shell.

    Costco Gas Has Ethanol

    Online reports indicate that Costco 91 unleaded gasoline does not contain ethanol because it is considered a Top Tier gasoline.

    Costco’s Kirkland Signature gasoline contains 10% of ethanol as per The Energy Independence.

    Costco Gas pumps also offer the ability to fill up with fuel.

    Is Costco Gas Bad For Your Car?

  • Costco gasoline will never cause you to lose your car.
  • Kirkland Signature gasoline actually contains high amounts of detergent additives. These help improve the quality of gas and the cleanliness of the engine.

    It is therefore classified as Top Tier gasoline.

    And Costco’s gasoline brand is above the US Environmental Protection Agency’s minimal additive requirements.

    AAA investigated the difference in so-called Top Tier gas from gas that met only the minimum requirements of the government.

    Intake valve deposits were also 19 percent lower in Top Tier fuel engines.

    Costco’s regular gas is as good or better than its premium gasoline?

    Costco offers both regular and premium Kirkland Signature gasoline. You can rest assured that your vehicle is fueled with high-quality fuel.

    All the fuel sold at Costco gas stations has higher than average quantities of detergent additives.

    Both Costco’s regular and premium gas are therefore considered Top Tier.

    Beyond that, the only difference between premium and regular Kirkland Signature gas is octane levels.

    Use the manufacturer’s recommended levels of octane to refuel your car.

    Which other gas stations offer “Top Tier” gasoline?

    Aside from Costco, there are plenty of other gas stations in the US that sell fuel that meets Top Tier standards.

    This means that fuel is higher than US government standards for fuel quality.

    To get an even better view of the stringent requirements, go to Top Tier Gas’ website.

    As of January 2020, some of the retail brands that sell Top Tier fuel at their gas stations include:

  • 76
  • ARCO
  • BP
  • Chevron
  • Esso
  • Mobil
  • Shell
  • Texaco
  • Wow
  • Convenience stores in your area may carry Top Tier certified fuel. You will find certified premium fuel in many different places, so Costco is not the only option.

    Costco will likely have significantly higher prices for gallons, however.

    Is Costco Gas Popular?

    Costco gasoline is a very popular choice. Costco Kirkland Signature gas is of high quality and is often the lowest priced option.

    But its most significant drawback is its popularity.

  • Costco gasoline refills can be a lengthy process. The lines at Costco’s gas stations are long. You could even end up waiting an hour!
  • While you are waiting, your friend could drive the Costco driver to the warehouse and assist you with any shopping needs.

  • Costco is open to all credit card holders.
  • Conclusion
  • Kirkland Signature gasoline is high-quality and great value at Costco gas stations.

    Costco’s regular and premium gas contain large amounts of detergent additives, which means that it meets the strict Top Tier standards for performance.

    It is still several cents cheaper than some of its closest rivals.

    The only downsides to filling up your car with Costco gas are the long lines at the gas stations and the annual membership fee you have to pay to use it.

    However, these drawbacks are far less than the benefits.
