If your advertising sounds like a Power Thirst commercial, I'm going to call it out, the same way I do with Lucas. It's not bashing, it's valid criticism. I'll call out any brand for misleading, totally false or outright ridiculous marketing, just like I did when Shell started posting piston pictures. Nobody gets a free pass to act like their audience is comprised of morons.
If Petro-Canada sent you an e-mail that was like "Our super jumbo elongator formula 9000 rebuilds your engine as you drive; stops wear in its tracks like a badger on cocaine and gets together the dad's of all the other oils and beats their heads in with a 2x4, THERE IS NOTHING BETTER!!!11111ONE" I'd be all over them for the same reason.
