So, were you wondering about who makes Costco synthetic oil?

To resolve your confusion, in this article, I will share all the information related to it. 

But the first thing you need to know is the name of Costco synthetic oil is Kirkland Motor Oil. It is Costco’s private label product.

Who Makes Costco Synthetic Oil?

As you already know that the synthetic oil that Costco sells is Kirkland Motor Oil. However, Costco doesn’t make the Kirkland oil. 

Actually, Warren distribution, located in North America, manufactures Kirkland Motor oil. Warren Distribution is the biggest private label oil mixer. 

They also make their own brand of Mag 1 oil. They combine good motor oils with good additive bundles.

The Kirkland oil is distributed by Costco Wholesale Corporation under its private label.

Where Are Costco Synthetic Oil Made?

Warren Distribution manufactures Kirkland Motor Oils in the United States. The company’s headquarters are in Omaha, Nebraska, and it has more than 2 million square feet of production and distribution facilities in several locations around the United States where it produces oil. 

Council Bluffs, Iowa, is one of these manufacturing hubs, with production buildings covering 2,40,000 square feet.

In addition, they have 6000 square feet of industrial space in Lake Guntersville, Alabama, and 340000 square feet in Houston, Texas. Albertville, Alabama, has a large oil manufacturing sector. 

Thus, from these facilities, the oil is handed over to Costco for distribution.

Are Costco Synthetic Oil Any Good?

Costco’s Kirkland brand may be a dark horse in the motor oil kingdom, but it has some remarkable features. These factors make this motor oil worthwhile to test.

When we think about buying engine oil, we want it to be both Dexos and API certified. 

The Dexos certification demonstrates that your car meets numerous conditions that allow it to meet the most recent emission standards. It also provides for better fuel economy.

Costco synthetic oil will provide you with both of these certificates. What else could you want?

In terms of resistance to power-robbing elements, it also surpasses the finest synthetic mixes.
