Change it if you'd like to, it sure isn't gonna hurt anything. The oil is moving threw there at a pretty good clip & it's the same oil that is in the pan so I've never messed with it, but some do & that's their choice.

The way that Ive heard it explained it that there was 2 different oil systems more or less in the truck, one top one bottom? If its all running threw the same system it seems pointless

Yep it's kinda like 2 systems but the oil all starts out & ends up in the same place, the oil pan. While I think it's pointless some think it benefits & I'm no expert...

I have 210k on a e99 with the small stock injectors ( I think 130cc) I don't have any real problems but I hear and can tell I am going to need to replace before 250k if I have the coin. IF not I'll run them until one goes BAD. I don't like to that "I believe in PM on your truck" I try to use 2 stroke oil or some kind of add and in the winter I really like the "XDP Polor" . I change my fuel filter about every 10k and oil 5k -7.5k Ihave the parts to do the Hutch mod and add lift pump& pre filter. That should help fuel pressure. I agree with all on the points: filter, additives, fuel pressure, HPOP pressure
I think we could do a whole tread on affects of fuel / HPOP oil has on injector life. Too much pressure is NOT good and poor pressure is bad too!! It soulds like I'll need a few beers and think about that one?

I had 320,000 on mine. I replaced them all, although only 2 were bad. However I used a fuel conditioner every fill up. Also oil was changed every 4,000 mi.

340K and have never had a valve cover off.
She is starting to get a little hard to start when cold so I am going to do injector orings and glow plugs before winter but she still runs great and fuel mileage has had been consistent all 340k miles.

I had my injectors rebuilt by Rosewood at 244k miles. I went with new (stock)nozzles and springs (lift pin). Much more engine power compared to the aged set of injectors. My old nozzles were only flowing about 80cc according to Jim. I didn't realize it at the time but my fuel mileage was suffering as well. I think there was about a 15-20% decline in mpg on the old injectors. I have about 32k miles on the rebuilt set and my mileage is right around 16.8 mpg with plenty of towing power. I expect this set to get me to the 400k mark and then I'll probably replace them with a brand new set.
My wife's truck has about 189k miles on it and I can tell that it is down on power slightly, very hard to tell while unloaded but it's more noticeable when towing. Fuel mileage is down as well. I plan on pulling the injectors and sending them to Jim around the 200k mark.
