Gang,

Here is the second UOA of the PS fluid in my FX4. Blackstone comments are below:

Metals are looking a little better in this sample, which is great. We're still not sure how much aluminum is okay for these units. Aluminum seems a bit high compared to our universal averages, and maybe iron and copper are elevated too, though the down-trend is reassuring. Note that we did find a trace of moisture in this sample. That probably shouldn't be there, but maybe it was introduced in the sampling process and isn't a problem. The trace of insolubles is fine. This oil was changed, so try resampling in about 60,000 miles again to monitor.

Enjoy!
