This was mostly highway driving, took a trip from Michigan to Connecticut.

Wow, nice improvement! This 3,000-mile run is a great place to start looking for the ideal oil change
interval for your Expedition. Now that we know how many miles are on the oil, we can start increasing the
miles until we find the ideal mix of wear/miles. Metals all tested at healthy levels, oil physical properties were
very good, and both air and oil filtration look top-notch. The TBN was very strong at 6.0, showing plenty of
active additive remaining for more use. Increase the interval to 5,000 miles, then check back about going
further. Nice engine!

Oil filter:
PureOne PL24651 (did not replace this oil change)

Air filter:
Fram CA8039 Extra Guard (replaced before this oil change cycle)

Nice improvement over what? Do you have another UOA to share? If 3K is to be your OCI (even if 5K is to be your OCI), unless you are getting free EP, I would switch to a conventional oil (any conventional oil--the cheaper the better as long as it meets API SM or SN). A premium synthetic is a waste at that OCI.

Because he wanted to?

Here's his previous UOA:

Correct, that is the reason. I had high iron (40ppm) on the last UOA. One response made me think I may have engine problems. Going for 5000mi or maybe skip right to 8000mi.
