Remember that many years ago, Pennzoil was the target of all kinds of stories about sludging engines, and those stories are still out there. Castrol experienced its share of that phenomenon, too. It's no surprise that the marketing is geared towards addressing that matter.
I can't think of any oil companies that aren't guilty of at least one instance of ridiculous marketing. Heck, if an oil company did it only once, they'd be saints.
