Here's the data from my third oil change. I used PUP 5w20. So far I have not ever had to top off the oil.

When it comes to the first sample, it's not unusual to find some higher metals and silicon. The metals are from new parts wearing in and getting acquainted with one another and the silicon is from sand casted parts and harmless sealers used to put the engine together. It might take a few oil changes to wash this stuff out, but eventually, your samples should look better than universal averages, which are under construction since these are new engines and we haven't seen many samples from them yet. The TBN was strong at 4.0 so try 8K miles next time.

There's a lot of nice progress to talk about in this sample. Copper has improved, and other metals have come
down a bit as well. Copper is still just high enough to mark, but another improvement like this next time should bring it
right down in range. Silicon might take another oil change or two to get there, but the progress is appropriate so far. The
TBN read 6.5, showing lots of active additive left in the oil. No fuel, moisture, or coolant was found. We guessed by
"5W/20 PUP" you meant Pennzoil Ultra, but let us know if that's not right. Nice progress!

The new 1.0L turbo engine in your Fiesta is coming along very nicely.
Wear metals have all improved. They are low and well balanced, showing that the engine made its way through the
wear-in process just fine. This is also a good sign that no mechanical problems are developing. The oil itself was free of
fuel and coolant contamination, and the viscosity was normal for a 5W/20. Low insolubles and silicon show good oil and
air filtration. The TBN came in strong, so feel free to try 12,000 miles on the next oil.
