There is no hype. The hype is created by the users, some like it. A lot don't like it and the people who does not like it, most of them are not users.
My suggestion is to evaluate it yourself. You can go to auto-rx website yourself, check out their forum. There are actual users or potential users (such as yourself) that ask questions and post answers based on their experience.
In my case, it works. I have used it in my own Camry and Suburban diesel. I have recommended to other people and they actually used it: my dad who owns another Suburban diesel, my friend who owns 2 Camry, 1 Lexus and 1 Rav-4, my friend who owns an Accord, etc. All of them have been satisfied.
Have I opened my valve cover, heck no. I don't have time to do those that is why I used Auto-RX. Don't have time to go to mechanics too much.
So, that is my story and I am sticking to it.
