I don't think many here even know about it.
What mileage/ condition and service is your motor? The AutoRX seems to be a great cleaner I had a buddy at work try it in an old beater that was using oil and it stopped in the rinse phase. All my current motors are so new, most products have little imediate affect on them.
Have you read the patent on auto RX? cool stuff.
