Just because Ron Popeil says it works does not mean it does. Car guys just love magic ingredients for their
oil, the "Snake
Oil" guys are always willing to take advantage of this need. There's a pretty good chance that the companies who manufacture the lubricants, working with the guys that build the cars have developed a product which will do the job without adding some additive. If the
oil needs it, it's probably already in there.
BTW, Zmax also keeps the elephants away. My buddy's been using it for 15 years now and he hasn't seen one elephant in his neighborhood. Proof!
