Costco, a multi-billion-dollar global retailer with warehouse club operations in eight countries, last week introduced its line of private label passenger car motor oil. 

Marketed under Costco’s Kirkland Signature™ brand name, the line includes three viscosity grades of synthetics (SAE 5W-30, 5W-20, and 0W-20). In addition to credentialed as an API licensed SN PLUS/ILSAC GF-5, the products are approved for use in all GM gasoline engines requiring dexos1™ Gen 2.

All three viscosity grades are currently available online, and the 5W-30 is starting to appear on shelves at Costco warehouse club stores.
