I added a whole bottle of ARX to my Honda that takes 4q. In hindsight, that's a lot of ARX. I see now that they dropped the 2oz for the filter dosage, so I'm 50% over-concentrated! How long should I run this? I'm at 1000-1200 miles now and am trying to get this treatment completed asap. I will re-use the ARX mix in a beater car, so that's no problem, not too big a waste. My 2nd question is about the Rinse/Completion Phase. According to the instructions, the Rinse Phase consists of nothing more than *changing* the oil??? How is that a "phase" if it takes 5 minutes without the car even running? The instructions are as confusing as ever. I assume the "Completion Phase" is the driving with the rinse oil? All I really want to know is that the end of it, Clean, change and Rinse? Afterwards synth oil is ok...2000 miles after the ARX is drined and fresh dino oil is added? Oye.
