I bought a 12 quart case of the stuff at Sam's Club for just under $22. I did a bit of Googling and it looks like it used to be bottled by SOPUS, but these say Warren Oil Company. I am assuming this is Warren as in Coastal Oil and not Warren as in ST and Mag 1.
Anyone ever use the stuff? It's API SL, SM, SN and ISLAC GF-5.
