Meets Dexos And API Standards
Both Dexos and API certifications have been achieved by Costco Kirkland Motor Oil, indicating its quality and safety. In order to obtain either of these certifications, oils must pass rigorous tests for viscosity, corrosion resistance, and thermal capacities.
In addition, these certifications provide optimum performance even under extreme conditions, such as high engine loads or high temperatures. Because of this, you avoid the risk of using low-quality oils in your vehicle when you use Costco Kirkland Motor Oil.

Frequently Asked Questions
What is Costco Kirkland Motor Oil?
This synthetic motor oil from Costco complies with API standards and improves engine performance, extends engine life, and reduces emissions.
A variety of weights are available, including 0W-20, 5W-20, and 5W-30, making it suitable for a variety of vehicles and conditions.
Is Costco Kirkland Motor Oil good?
In terms of its overall effectiveness, Kirkland motor oil can be rated as “good” because it meets or exceeds all industry standards, but when it comes to prices/performance metrics relevant to the purchase of the vehicle, such as gas mileage and efficiency, its overall effectiveness depends on how it compares with other companies’ products.
How does it compare to other brands?
Costco’s Kirkland lubricants contain special synthetic additives that protect engines from oxidation at higher temperatures than regular oils allow, which makes them more effective than regular gasoline or diesel oils. This prevents oxidation at higher temperatures (i.e. weather climates) and increases engine longevity.
In addition, this type of oil offers superior viscosity levels, leading to improved fuel economy & faster starts during the colder months.
What is the recommended interval for changing Kirkland brand oil?
Generally speaking, manufacturers recommend changing conventional automotive oils after 3 months/3000 miles, depending on the model and make of your car. However, synthetic types such as those provided by Costco typically last up to 6 months/5000+ miles depending on usage habits associated with driving style and climate changes throughout the year, for example, cars driven primarily in the summer may lose reliability more quickly than those driven primarily in the winter.
