I've been told many things over the years also. Some I found to be true and some of it pure nonsense. When I was young, I often soaked in all the stuff the old-timers told me. It took me awhile to learn that young BS artists grow up to be old ones. Age does not always add to a person's credibility.
I've been told many times that diesels have more low-end torque because the air-intake is always wide-open. That is still written in a few text books. Not mentioned is that some diesels do not run wide-open air intakes - like some of my IH diesel tractors with air-governed fuel injection pumps.
