Are these all Group II, sourced from the same refinery (refineries)? Does QS still use base oil from the Newell, WV refinery, even though they sold it?
BTW... I understand Calumet is demolishing the old Rouseville Pennzoil refinery. I guess they bought it, tried to resell, and did not find any takers.
