  • Costco is known for its great deals on everyday necessities, including gas!
  • Costco might be the best place for you to refill your gas tank. The first thing you should do is check out Costco’s gas quality.

    It was a lot of work, but here are my findings.

    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. Costco offers gas at many cents per gallon less than its average competitor.

    How much is high-quality gasoline at Costco worth? Why are these low prices?

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

    How Much Does Costco Gas Cost?

    Costco is not responsible for the actual cost of Kirkland Signature Gas.

    However, Costco is able to keep prices lower than other gas stations, regardless of how they fluctuate.

    A 2018 Costco report found that gas is on average 21 cents cheaper than the competition.

    Others have claimed that the difference in price is less than 10 to 15 cents. Either way, the price per fill-up adds up and can amount to some impressive savings.

    What is the reason Costco Gas prices are so low?

    Costco is able to keep gas prices at such a low price because they charge a membership fee. Costco Kirkland Signature gas is only available to Costco Members.

    A personal member costs $60 to $120 each year depending on the benefits available.

    Costco charges membership fees for about 75%, which allows them to keep their prices very low for everything.

    But, it is unlikely that you will make the Costco membership worth your while if you don’t fill up your car at Costco often.

    Costco would require you to refill your tank at least 35 times per calendar year to offset the price of membership.

  • Costco Gas Vs Shell, Mobil, Texaco, Chevron, & Exxon
  • Reddit threads show that Costco gasoline is essentially the equivalent quality of many other gas companies such as Shell and Mobil, Texaco or Chevron.

    Reddit users also believe that Costco purchases their gasoline from these refineries, and then renames the gas under its Kirkland brand.

    Costco gasoline and Shell are only two different things. Costco uses fuel additives (to save money) to make its gas cheaper than the fuel rack at the refinery.

    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 has high levels of detergent additives. This helps to increase the quality of your vehicle’s gas as well as improve its cleanliness.

    The gasoline can therefore be classified as Top Tier.

    In other words, Costco’s gas brand exceeds the minimal additive requirements established by the Environmental Protection Agency of the United States.

    AAA evaluated the difference between Top Tier gas and those that met just the government’s minimum specifications.

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

    Costco Regular Gas Is as Good As Premium Gas

    Costco has great Kirkland Signature gasoline in regular and premium grades.

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

    Therefore, Costco’s Premium and Regular Gas meet the Top Tier Standards.

    Other than this, there are only two main differences between regular Kirkland Signature gas and premium Kirkland Signature.

    Always refuel with the octane levels specified in the owner’s manual of your car.

    Are There Other Gas Stations That Sell “Top Tier Gas?”

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

    This describes fuel which is at a higher level than US government requirements.

    Visit the Top Tier Gas Website to get a better idea of their strict specifications.

    Some of the retailers that carry Top Tier gasoline at gas stations as of January 2020 include:

  • 76
  • ARCO
  • BP
  • Chevron
  • Esso
  • Mobil
  • Shell
  • Texaco
  • WOW
  • You may find local convenience shops that carry Top Tier approved fuel. You can also purchase high-quality certified fuel at many other locations, including Costco.

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

    Is Costco Gas Popular?

    Costco gasoline, yes! It is quite popular. Costco Kirkland Signature gas is of high quality and is often the lowest priced option.

    But, it is also its biggest disadvantage.

  • Costco gasoline refills can be a lengthy process. Costco gas station lines can be quite 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.

  • Costco Gas is available for purchase. Please see the Costco Cash Card posts to learn if Costco gas accepts credit cards, and what Costco Gas hours are.
  • Conclusion
  • Kirkland Signature gasoline is high-quality and great value at Costco gas stations.

    Costco’s Premium and Regular Gas contain high amounts of detergent additives. This gas meets all the requirements for Top Tier performance.

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

    Costco gasoline can be expensive.

    However, these drawbacks are far less than the benefits.
