I'm not an expert on this industry either, but do you have a source for
the above? Is the industry lying when they say that at peak demand,
refineries are generally at capacity?

From what I've read, we are at a period of running at capacity. Which means
that we are getting close to a period in which (as Mike put it) "the market
grows and there is a shortage." Which will be followed by a period in which (as
Mike put it) "Then everybody builds more and there is a glut again."
