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!
