Snake oil salesmen are only concerned with facts that support their product and either ignore, dispute or misrepresent those that do not.Yes, I'm pretty clear on how a regen works.
Go watch that video that you suggested. At or about the 6:15 minute mark, the speaker shows his ignorance. He's talking about his brother in law's Duramax and he says they aren't sure if it's ever regenerated because the light on the dash has never come on. It's clear the guy is just trying to sell a product, without regard for the facts.
