May have missed it, but when did you last change your crankcase filter.
On my 2013 Cummins, it should have been done at the 5 year mark, but the shop that does my work missed it and it was not changed until year 9 service.

Wait till you see the clouds of white smoke and the noise coming from your diesel and then the fun begins. Diesels are extremely expensive to keep running. Good luck and put money aside for repairs. My diesel had less than 70,000 miles on it when it needed all those repairs. Diesels lasting a half million miles is just a myth put out by diesel makers.

No, this is wrong. His is an ISC, an engine that is a common sight in large trucks. We have semi tractors at work using the same basic design, though now called the L9.-we also have a tractor with over 570,000 HARD miles on an ISX15. While the tractor feels pretty worn out, the engine is fine...starts instantly even cold and pulls hard.
My bus is over 330,000 miles.

Think I am down to it being in the fuel, the inter-cooler or was burned. Eager to see the cause.

Are you positively sure that you put the proper amount of oil in the first place ? At this point after all you have checked, this does not make sense.

If you have no leaks and are not seeing white smoke from the exhaust then you need to check the blow-by. If you do have that much blow-by then there should be signs of that in the engine bay. It should be covered with oily residue given the one quart every 30 miles or so consumption, which is a staggering amount.
A quick test is to loosen but not remove the oil filler cap from the top of the engine with the engine running. If your compression rings are good and there is no blow-by then the oil cap should rest in in place without being bumped out by the crank case pressure. If, however it is pushed out by crank case pressure then you may have one or more cylinders with excessive blow-by.
If you have the skillset and the tools you can run a compression test but that is quite a bit more involved and requires removing the injectors from the engine. But before going that far, have a Cummins diesel professional run a more comprehensive blow-by test first.

Oil Loss
How long have you been using synthetic oil?
My diesel guy says it can cause damage to gaskets and seals.

WOW!!
If I had lost all that oil, and knew as much about your engine as you do, I'd be doing a lot of talking to myself. It would be driving me crazy.
Here's an idea...Fill the motor with the correct amount of oil, and take it for another drive. Say, about 100 miles. See if the problem duplicates itself by losing 3.5 quarts. This would eliminate possible owner error.
Good Luck....

I'll try to answer the questions
The engine was between the marks since last change and at that time I added almost two cases of Amsoil, so yes it was the proper amount. This is the first time in almost a year (since last change) that the oil was not at the correct level.
The blow-by test is on the schedule to perform once I'm able to muscle that air filter back into place and fill engine with fresh oil. Also some other checks my diesel mechanic friend suggested yesterday as I have previously posted.
I do plan on running a short trip if I come up empty after all my checks are done and yes, it is driving me crazy.
If all of this turns up nothing, including the test run, then I turn to the second to last possible alternative. The final campground this year (I call it unfriendly valley) was where we encounter the monsoon like rains nonstop. So either the intake filter can was temporarily plugged with water, which caused the engine to suck it from the pan or it was tampered with.

My 2003 5.9 Cummins failed at 74,000 miles, and had to be towed to Cummins. They want $49,700 to replace it.
