I changed the oil with that sample. At my first change at 10k Ford "conveniently" forgot to get my sample even though I asked and left all the parts in the center console. My second sample, as you could see, had various "elevated" metals. All of my driving is city...car has been out of town once and that was when it had 2000 miles on it. Like you, I think all the start stop ICE to EV mode is why the fuel numbers are up, and without saying it, it's what Blackstone feels as well. I just felt like I spilt gas all over me when I changed the oil secondary to the smell. I did the third oil change at 5700, therefore I felt a TBN was unnecessary because I wanted to see if it was just engine break in or miles between samples that resulted in the high metal levels. In another 5-6k I will change out the oil and get a sample and compare, and then slowly start building up the miles between samples. There are not many people on the fordfusionhybridforum.com that get samples from Blackstone, and another user told me about you and your sample data. It's nice to have someone else to compare data with.

Ah ha...found it 13_FUSION-081415-2.pdf

fbov...like your last oil change result, I had "normal" high fuel in mine as well. Although I drive a Fusion Hybrid, the engine is still the same. Blackstone didn't seem to care however. When I asked they said as long as viscosity is okay (like they told you), it should be okay. Apparently according to them high fuel percentage is prevalent in Prius'. I would attempt to upload my pdf file however I can't seem to attach a document.
