Who Sells Kirkland Motor Oil?
All types of Kirkland’s motor oil are marketed by the retail giant Costco. Also, Kirkland is a prominent home brand of Costco serving its customers.
As a result, Kirkland motor oils are only available at Costco stores all around the world. You are likely to find Costco stores in the USA, Canada, and all over the UK.
Kirkland Motor Oil Types
Based on viscosities, Kirkland Motor oils can be mainly divided into four main types. These are:
- SAE 0W 20
- SAE 5W 20
- SAE 5W 30
- SAE 15W 40 ck Diesel engine oil
Starting with 0W 20, which is one of the best-selling full synthetic engine oils from Kirkland, this thinner oil is perfect for colder climates. It currently retails for $39.99 for a 5 quart twin pack from Costco direct and can be bought here. After that, 5W 30 which is the same price here and is a thicker oil has also earned many good reviews for its performance and quality. It comes in at the same price as the 0W 20 at the time of writing is $39.99 for a 5 quart twin pack, you can see a lot of positive reviews here.
It is even compared by some buyers as being at the same level as Mobil 1, quite how they can measure that without a full laboratory experiment is unknown! but Costco brand products are generally very high quality so it is possible.
Finally, the SAE 15W 40 is designed for on- and off-road diesel engines and Kirkland states that it provides outstanding year-round protection and performance. Comes in 3 x 1-gallon bottles for $39.99, you can pick them up from Costco here .
Are Kirkland Dexos and API Approved?
Dexos certification is mainly given when a motor oil meets recent emission standards along with some other conditions. An excellent fuel-efficient system is also ensured if any motor oil meets Dexos standards.
On the other hand, API certification is there to ensure you of the quality of the company behind the Oil. Both of these certifications are essential and some would say “must-have” certifications for motor oils.
It is a good thing then, but not surprising given Costco’s usual quality, that Kirkland’s motor oil is both Dexos and API approved and hence has gained the trust of their customers within a short time.
Are They Any Good?
If motor oil is good or not mainly depends on the certification it received for its overall performance. Among them, Dexos and API accreditation are some of the important certifications that customers mainly seek. After all, most people just assume the oil will do its job and forget all about it until the next time the car is serviced.
As mentioned in the last section, Kirkland motor oil meets both standards while giving outstanding performance throughout.
In most cases, they have even outperformed when compared to other big brands for longevity and of course, competitive pricing.
Is Kirkland Oil Safe to Use?
Looking at the price, it wouldn’t be a surprise if you were suspect about the quality. Customers keep wondering if these inexpensive oils will be worth the money or not. Are they even safe to use?
They most definitely are. Kirkland motor oil is also known to extend your engine life as they come with advanced wear protection. To add to that Warren Distribution is a proven supplier of such products and they will likely be made to the same exacting standards as more expensive brands.
However, to get a further and clearer idea we would suggest you have a watch of this video: (interstingly after some testing the Oil reviewer concludes that the Supertech Oil, Amazon Basics Oil and Kirkland Engine Oil are all Identical! and are all made by Warren Distribution. Hows that for a knockout fact!
