Yes. I'm sure Shell made completely sure before plastering that in public, so I believe what they wrote. I'd be first to blame batch screwup or something wrong in the logistical chain. Nonetheless, it seems that the oil companies test each others' products on a fairly continual basis, since they seem to find anything wrong on behalf of each other far quicker than does PQIA or API or anyone else. Of course, it's really the core duty of the PQIA to monitor the majors, simply because the other majors will never let one of them get away with anything. Shell, Mobil, and Valvoline certainly don't bother with press releases about City Star oil.
