2008 Ford Crown Victoria Police, 4.6L in police service.
First run on Schaeffer's Supreme 7000 5W-20 (numbers on left)
Vehicle is equipped with an hour meter which only accumulates time while engine is running in park.
6039 mi + 156 hrs of idle time on oil. For reference, Ford considers 1 hr of idle time equivalent to 33 mi of driving=11,187 mi equivalent, total.
Towards the end of the run the alternator pulley loosened up and began to slip on the shaft. The serpentine belt was destroyed by the resulting heat production. The engine over heated and required the replacement of 1.5 gal of coolant to refill.
37,647 mi on vehicle
Napa Gold oil filter
0 make up oil, oil level was just above add mark at time of sampling.

Seems like the oil handled real well considering the hours and the overheating. TBN is solid, can't wait to get my case of Schaeffer's(wish my local rep had the 5w20 though).
That is excellent considering the abuse! Gives me confidence in my upcoming 5k UOA. I hope to be able to go 6-7k, UOA backed.
That is an excellent report. What was the time span for this run?
156 hours of idle time = to many stops at Dunkin Donuts. 
Very impressive overall, especially that the TBN retention is almost half of what it started at. IIRC this oil is a blend, not even considered a full synthetic.
Nice presentation, if Schaeffer's stopped playing hide&seek and made the price more tolerable they would be running three shifts at their production facilities.

According to Schaeffer's, the 7000 series is a blend of Group II+ and PAO.

Great results, and a 20 grade oil. The idle time is what kills things, then overheating. I can only imagine what a 10,000 mile normal use run would have looked like!

Idle time is from directing traffic, running the lights at scenes, traffic stops, etc. No Dunkin Donuts in our coverage area yet, but we're hoping!
LOL- Now there's a place that won't have to worry about armed robberies!
Nope, the 7000 series 5W-20 is a SM oil.
