Nearly 1000k's into my engine flush stage on 200,000km V6 Ecotec 3.8litre. Ran the clean mode for slightly over the advised period. Even a few thousand k's into the clean mode i already felt a noted difference in the car, with smoother running, acceleration etc. Oil i was using was Mobil 2000 20W50 Mineral oil, same i am using now for the flush.
I just flushed and changed most fluid on my power steering, renewed hoses as well. When i started draining the reservoir i could see small crusty bits of gunk at the bottom. The fluid was darkened in the time i added the auto-rx even though it was dark before, i had never changed the fluid in the pump for the whole 200,000k's. The improvement i got in the steering was even prior to changing the fluid. I used to have a clicking noise when turning left, it was like a metallic clicking noise. I thought it was suspension related possibly still is but it certainly went away after a few hundred k's on the Rx. It has been doing it for a year or so, but now its pretty much gone, i try to make it come back but it doesnt....now that i have flushed it out, the steering is definately improved, with the steering not as loose(soft and spongy). Fantastic improvement. I will drain the fluid again in a few hundred k's to get it all out.
