    Costco Gas Prices: How Much?

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

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

    Costco gas prices are on the average around 21 cents per gallon lower than those of its competition, according to a report from 2018.

    Other platforms have reported that the price difference is closer to around 10 or 15 cents. Either way, the price per fill-up adds up and can amount to some impressive savings.

    Why Are Costco Gas Prices So Low?

    Costco is able to keep gas prices at such a low price because they charge a membership fee. Costco Kirkland Signature gas cannot be bought by anyone other than Costco members.

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

    Costco accounts for 75% to 75% in profits from its membership. Costco is able to keep grocery prices as low as possible by keeping the price of gasoline and groceries at a reasonable level.

    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.

    According to Costco, in order to cover the annual membership cost, one would need to fuel at Costco 35 times per year. This assumes that you use Costco to access fuel.

  • Costco Gas Vs Shell, Mobil, Texaco, Chevron, & Exxon
  • Reddit user threads have shown that Costco’s gas is essentially of the same quality or higher than many other gas companies including 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.

    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 Kirkland Signature gasoline does include 10% ethanol to meet The Energy Independence requirement.

    Costco Gas gas pumps can also be filled with the fuel mix.

    Is Costco Gas Bad For Your Car?

  • Costco gasoline is not going to ruin 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.

    You can classify it 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.

    They also found 19 times less intake valve deposits in Top Tier fuel-powered engines.

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

    Whether you buy regular or premium Kirkland Signature gasoline from Costco, you can be sure you’re filling up your car with great quality fuel.

    Costco’s gas stations have higher-than average amounts of detergent additives.

    Thus, Costco regular gas and its premium gasoline meet Top Tier standards.

    The main difference between premium Kirkland Signature gasoline and regular Kirkland Signaturegas is its octane content.

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

    Is there a gas station that offers “Top Tier”?

    Costco may not be the only American gas station to sell Top Tier fuel.

    This is fuel with a higher fuel standard than US government minimum fuel requirements.

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

    As of January 2020 some retail brands which sell Top Tier fuel at stations are:

  • 76
  • ARCO
  • BP
  • Chevron
  • Esso
  • Mobil
  • Shell
  • Texaco
  • Wow
  • Local convenience stores may sell Top Tier fuel. Also, there may be other places that sell certified high-quality fuel.

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

    Is Costco Gas Popular?

    Yes, Costco gasoline is very popular – and it’s not hard to see why! Costco Kirkland Signature fuel is high quality. It is also very affordable.

    However, its popularity is in many ways its biggest drawback.

  • Costco fuel will make it more difficult to fill up your vehicle with Costco fuel. It can take a while before you are allowed to go. The lines at Costco’s gas stations are long. Sometimes, you could wait for up to one hour.
  • But, you might be able to have someone else in your car go into Costco and do the necessary shopping while waiting.

  • Costco gasoline is an option for those who are looking to test it. Check out these posts: Costco Cash Card, Costco Gas Accepts Credit Cards, Costco Gas Opening Hours!
  • Conclusion
  • Kirkland Signature gasoline, which is sold at Costco gas stations, offers great quality and great value.

    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’s still a few cents more expensive per gallon that many of its closest competition.

    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.

    The benefits outweigh any drawbacks.
