Napa Gold Oil Filter + air filter. Police service-105,256mi and 2509 hrs at time of sample. 15,052mi on oil + 327 hrs of idle time. (Hour meter only logs time while vehicle is running in park-Ford considers every hour of idle time to be equivalent to 33 mi of driving.) Oil in service for 4.5 months. Filter change about 10k into the interval-40 oz of make up oil (50/50 mix of Schaeffer's 7k 5W-20 and Mobil 1 5W-30) added including filter change. Car overheated twice near the end of this interval. The officer refilled the coolant and took the car back out where it overheated a second time. Car was driven back to the station after both episodes of overheating. New fan was installed and the car remains in service with no further repairs. This sample on Left-previous fill middle and right(also ASM), VOA far Right.

Oil held up very well despite the severe service. I'd be happy with it.
