Hello!
A lot has changed for me since ive been in here last!
I no longer work for Cummins, and i now work for the "Largest Surface Coal Mine in North America". 
Im a Light vehicle mechanic, and our fleet consists mostly of F350 4x4 pickups and Vans with the Triton 5.4 engine. Some 3 valve, and a lot of 2 valve. We also have a few V10's and a few 6.0 Powerstrokes. we have in our light vehicle fleet maybe 100 to 150 trucks, vans and bus's.
Now, the setup is;
we use a standard conoco oil in manufactures recomended weights, and all of our filters are Napa Gold. 
these vehicles are getting PM'ed about every 3 weeks ( YEAH!) and the oil comes out darkened, but mostly still amber see thru. All filters are changed every pm, including the air/oil/tranny/fuel, and also the fuel cap is replaced every time.
We are seeing about 30k miles on the 3v before they are just plain wore out. 
we replace the whole thing with a Ford Brand long block, and it solves all the problems we have with it.
now the 'stroke. as you may or may not know they have an oil log, thats now all curved and so, i suppose to help cut down on noise, but anyways, all the injectors are high pressure oil activated.
At about 20 to 30 thousand miles, the strokes stop starting at a certain OIL temp. They WILL start at an oil temp of 177 degrees, but NOT at 184 degrees. and no matter what we do we cant fix it, i mean NO MATTER WHAT. This has happened about 6 times now with year 2005 powerstroke 6.0's. One engine we decided to replace everything to see if we COULD fix it, the oil pump, all injectors, the PCM, the main harness, all sensors, the high pressure pump, the main fuel pump, the lift pump, the fiters, i mean everything, and the only thing that fixed it was a completely new ford longblock. Runs like new now....
I strongly believe that the root of our problem is inferior oil, and inferior oil filtration on an engine that is litterally driven like a stock car engine 24 hours a day 7 days a week.
My purpose of this thread is to aquire information to compile a report to my boss on the negatives of our setup, and to suggest an alternative oil/filter combination.
This place has money! On a whim of a flier he went out and bout 3500 collars worth of these magnet called 'the bear trap' which are great at falling off the filter never to be seen again.
Im leaning twords some synthetic valvoline oils, and fleetguard stratopore filters.
ANY information or insight will be greatly apreciated!
THANKS!!!
BOB IS THE MAN!
SEAN!
