I was on the rural king Facebook page and say the post saying new bottle same great product. In the comments they replied that they had switched suppliers. Take a look.
I've got a quart bottle of the "new" Warren Oil stuff. It has a Dexos number, but it doesn't show up on the Dexos database. I think a single quart was $2.99 for group III which (I think) was the same price as the Citgo stock was. Purchased in late 2019 and there were still a few bottles of Citgo hanging around on the shelves-- 5w30 was all Warren Oil.
