Outside of YouTube channel like project farm. Is there any independent empirical evidence that diesel fuel additives actually work? Now I am not talking about the winter additives to keep the diesel from gelling. I am just talking about you fill up and dump some fuel additive in. I don’t want what someone has experienced or what a company claims it can do that’s called antidotal evidence and can’t be independently verified. It’s nice to know that it works for a person but it’s not empirically proven. So if anyone has independent sources that prove what works. I would be interested.
