Rick, in relation to the EGR. Would the EGR "delete" that is recommended by some be helpful in keeping the oil cleaner, therefore helping prolong engine life, also preserving turbos.

It reduces soot loading, but oil change intervals are determined with this in mind.
One of my oil mentors major condemnation observation was soot loading in the trucks under his care. He used 2.5-3% which is ridiculously high.
At the time (over 15 years ago) his fleet average oil change interval was 96,000km.
Detroit Diesel pulled one of his DD60 Series engines down at 1,000,000km as a demonstration and all measurements were within factory specs with minimal sludge evident, so it went back together and back into service.
In other words don't sweat it.
Air filtration is far more important for engine life than oil filtration or shortened change intervals.
You can be changing the oil at 5,000km but if you are getting any unfiltered air past the air filter seal or through it in the case of oiled cotton gauze, you are shortening engine life.
TD5's were notorious for this, quite a few brands didn't seal in the air box properly, and anyone that's been around dozers and graders have stories of engines being dusted in a few hours when an air cleaner is compromised.
Just don't be tempted to change it too often, that's nearly as bad, an air cleaners efficiency increases as it loads.
5,000km is total overkill using Delo, it'd do 10,000km pretty easily if its mostly long run highway miles.
The TD42T has a big sump and is easy on the oil, surprisingly easier on oil than the 300Tdi.
Back in the 500ppm sulphur fuel days I was able to easily go 20,000km using a premium full syn 5W-40 oil and the old girl was towing horses.
All proved through used oil analysis.
That engine had the combination bypass filter as the secondary filter, too. Some use two full flows
Prior to that I was changing the oil every two to three weeks using Fuchs 15w-40, that's how quickly the 5,000km was coming around.
I'd have to pull the old oil tests but IIRC Delvac 1 was running the same wear metal numbers at 15-20,000km as the Fuchs at 5,000 and soot loading was fine.
I only changed it at 20k as we were in front financially at that point, the oil still had plenty of life in it.
When I last heard that engine had close to 500,000km and was running sweetly, it just had a little oil going down the stem seals first thing.
