I ran PYB in my fusion as the first oci after I bought it. Ran it 7500 miles commuting on the interstates around Atlanta. Still could see light through it when I drained it and it got a couple chunks of sludge out.
Try it for 200K and report back. I have 212K on my 2007 Fusion at 10K OCIs and my engine is like new clean, and shows no sign of engine wear on 10K OCIs.
