Well, your guy completely (almost) blew by the FR3 by Hot Shots, he mentioned it and kinda bulged his eyes or something. My Chrysler 200 used oil from the time it was new. Probably had to add oil 4 or 5 times to a 5000 mi oil change . Fresh oil change, I added the FR3 when it got time for the first add. The next time I checked, it was half way down the add mark, and stayed there to the next oil change. Had that car for 8 years. Not saying that all additives work, but it would be impossible for that guy to un-ring the bell for me on FR3.
