Many of you are familiar with the issue I had with my Fusion earlier this year, which required top-end work. For those of you not familiar - Cylinder 1 developed a problem with one of the exhaust valves which required removal of the head and a valve job. Details can be found starting about half way down Page 1 of this thread.
As part of the work, they put new Motorcraft 5w-20 oil in, and a new MC FL910s filter on.
I had planned on doing an oil change after about 1,500 miles of driving following the work, but that ended up going out to 2,864 miles. I put over 500 miles per week on the car, and I was extremely busy with work, etc.. so this was the first chance I got to set aside enough time to do the oil change, etc.
Here's the results of the UOA on this oil. More or less what I expected, following head/valve work.
Had I not told them about the work performed prior to this change, I suspect their comments would have been substantially different.
Wear metals don't actually look TOO bad, surprisingly.. granted, they are higher, but not massively so.
Silicon is about 15 times higher than my average for this engine over the last 30,000 miles, but that's to be expected. After all, the head was actually off the engine for over 3 weeks, and they DID use some silicon-based sealers in some spots during reassembly.
As to the sodium - The oil fill that was in the car when I brought it in was Valvoline Next-Gen, which has sodium in its add-pack, so I suspect there was some of that left in the sump after they changed everything out.
Thoughts?
