As far as the ARX cycle, it is still just a bit too early to tell. I did the clean and rinse cycle, and now I am on the first real oil interval where I am monitoring consumption. I have 2500 miles on this oil change and it is about a half a quart low. So, it is looking good. Previously, I used about a quart per 1500 miles. I run my oil for the whole 7500 miles, so I will report the total consumption for the whole oil change interval. I do a little over 1000 miles a month.

As far as other observations; I looked at the oil filter after the clean phase and there were some gritty particles in the filter media. Not a lot, but some. After the rinse phase, there was not much in the filter media. The car seems to run a bit smoother with a bit more power, but I must admit that could all be the placebo effect.

All in all it was a fun little experiment, and I think it will reduce my oil consumption a bit. Based on all the reports on other forums, I am also convinced it helped clean "ring packs".

I decided not to do the second cycle. My truck has seen synthetic oil for almost its entire life, so I dont think it is that dirty inside. Who knows?!
