    Costco Gas Costs How Much

    Costco cannot control the cost of Kirkland Signature gasoline, as can all other gas prices.

    Costco’s prices are lower than those at other stations, regardless of fluctuations.

    According to a 2018 report, Costco’s gas costs an average of around 21 cents less per gallon than its competitors.

    Other websites have stated that the cost difference between fill-ups is close to 10 or 15cents. However, each fill-up costs more and can result in significant savings.

    Why is Costco Gas so Cheap?

    Costco charges a fee to its members so that gas prices can be kept at a remarkable low level. Costco Kirkland Signature gas only members can purchase

    A personal membership costs between $60 and $120 per year, depending on the benefits you want access to.

    Costco membership fees account for approximately 75% of its profits. This allows Costco to maintain low prices on all products, from groceries to gasoline.

    If you do not fill up your Costco car regularly, the membership will be ineffective.

    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
  • Reddit users have stated that Costco gas is basically the same quality and quantity as most other companies such as Shell, Mobil. Texaco. Chevron.

    Reddit users are also claiming that Costco is the one who buys its gas from these refineries. Kirkland then names it.

    Costco gas differs from Shell in that Costco can add fuel additives directly on-site (to make money) rather than using the refined fuel rack.

    Costco gas has the same additive requirements that Mobil, Texaco or Shell.

    Is Costco Gas Bad For Your Car?

  • Costco gas will not cause damage to your vehicle!
  • Kirkland Signature gasoline actually contains high amounts of detergent additives. These help improve the quality of gas and the cleanliness of the engine.

    It can also be classified as Top Tier gasoline.

    Or, in other words, Costco’s own-brand gas surpasses the minimum additive requirements set by the US government’s Environmental Protection Agency.

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

    Additionally, they found that engines that ran on Top Tier fuel averaged 19 times fewer intake valve deposits.

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

    Costco sells premium Kirkland Signature gas, so you know you are getting great fuel.

    Costco gasoline stations sell fuel with higher amounts of detergent additives than the average.

    So, both Costco’s premium and regular gas meet Top Tier standards.

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

    Make sure you only refuel at the specified octane level in your owner’s manual.

    Which other gas stations offer “Top Tier” gasoline?

    Other than Costco there are many gas stations across the US which sell gasoline that is Top Tier compliant.

    This refers to fuel that is of a higher standard than the US government’s minimum requirements for fuel quality.

    You can learn more about their exact specifications by visiting the Top Tier Gas website.

    As of January 2020, Top Tier Fuel is sold at some gas stations by several retail brands:

  • 76
  • ARCO
  • BP
  • Chevron
  • Esso
  • Mobil
  • Shell
  • Texaco
  • Wow
  • You may find local convenience shops that carry Top Tier approved fuel. So, in addition to Costco, you can purchase certified high-quality fuel from lots of different locations.

    Costco prices could be much lower than the average for a gallon.

    Is Costco Gas Popular?

    Costco gasoline, yes! It is quite popular. Costco Kirkland Signature Gas is not only high-quality, but is also often the most economical option.

    But, it is also its biggest disadvantage.

  • Costco gas will not be available for purchase. This means that you may need to queue up to get your fuel. Costco’s lines for gas stations can get long. Even an hour could be enough to delay you!
  • This is a great way to make sure you don’t have to wait for your turn, and let someone get in your car so they can go shopping at Costco while you wait.

  • If you are interested in trying Costco Gas, don’t forget to see my posts on Costco Cash Card, if Costco gas takes credit cards and the Costco Gas opening hours!
  • Conclusion
  • Kirkland Signature gasoline, which is sold at Costco gas stations, offers great quality and great value.

    Costco’s premium as well as regular gas have high levels of detergent additives. These ensure that the product meets rigorous Top Tier performance standards.

    And, it still manages to be several cents cheaper per gallon than many of its closest competitors.

    Costco gas is expensive and can lead to long waits at gas stations.

    However, these drawbacks are far less than the benefits.
