If I sent out any mixed signals, my original question wasn't intended to be hostile to ARX. It's a normal condition for people to have second thoughts after making any major decision. I was struggling with the issues, looking at ARX from every possible angle. That's all I wanted to do. Verify the performance of ARX from another angle.
As usual, Terry and MolaKule provided wonderfully complete answers. Some people may notice that no one directly answered my mileage question, except MAJA. I had hoped someone would come forward with 100-200K on their engine after ARX, but no one did. If anyone considers this a negative result, I should play the Devil's advocate.
As Frank mentioned above, ARX has been used in car engines for over five years. There are probably a few people by now who have post-ARX mileages over 100K. If these people had experienced ANY negative long-term effects, then we would have seen some credible negative posts, posts transmitted heavily across the Internet. Mad people need to vent. They vent hard. Plenty of other people want to be the first one to find/quote their horror story.
No such instances have occurred. People who experience positive results tend to remain silent. It's business as usual. If they are problem free, then why stop their busy schedules to post the fact? If the product works as advertised, why say more? No complaints. Just as with Terry's lab results, it's a case of "no news is good news."
