I`m pretty sure it`s warren because the jugs don`t look like the Mobil jug`s right now.
Yes, you're right, it might still be Warren / WPP even if the bottle does not have WPP stamped at the bottom. I think Warren just used another bottle supplier for their current stash. In fact, the stamp "G" at the bottom of their bottle also appears in all SOPUS and Valvoline products - two different companies.
