Warren Distribution is the company that specializes in private label petroleum products, including synthetic oils for AmazonBasics, Costco Kirkland, and Walmart Syntech. Numerous reviews can be found on these synthetics, and overwhelmingly positive reviews.
For Costco shoppers, their Kirkland 0W-20 specifies ”For use in gasoline, ex-fuel or gasoline-electric hybrid vehicles requiring SAE 0W-20 API SN PLUS." For the oil change DIY'er, it has also been on promotion in the recent past, & likely again in near future: Two-Pack of 5-qt containers for $25-$26. That makes it only $2.50/qt.
