Meteorite??
When i say slight fuel haze, i mean the only time you can see it is if it is directly in the sunlight. If its cloudy you cant see it. It's not blue, or white, it's greyish black soot.Sounds as have a nozzle or more going south. Easier getting them out and checked now then after eat a piston from washout.
Would it be from injectors being worn? Or dirty, i have taken out my LB7 Duramax injectors disassembled and cleaned in my ultrasonic cleaner to get by. But if the injector is straight worn out not much one can do unless there is a source for new replacement parts. Bosch has a stranglehold on the manufacturing for the LB7 injectors i couldn't find replacement ball and seat in the injector. So had to buy new injectors. I've also noticed that cold weather starting has gotten a little harder. This 3306 has been the best cold starting diesel ive seen. Use to fire up first rotation. But now it takes a second or two of cranking and chugs a little when cold.Still suspect a nozzle not atomizing properly
In my truck i notice almost 10% difference in fuel consumption summer vs winter fuel. But my comparisons are both between winter fuel.Would make sense if fuel consumption is up. I don't diesel varies much other than winter and summer blend. Gas on the other hand seems to vary quite a bit on fuel consumption. I think they alter the additives and it can make quite a difference.
3306 uses nozzles rather than electronic injectors. They have a pop-off pressure of something like 2500 psi. With age they sometimes pop early or don't close completely. The orifices also tend to get bored out a bit with age, which changes the spray pattern and doesn't atomize the fuel as well, but they tend to run strong.Would it be from injectors being worn?

I believe pulling the nozzles and having a pop-off test done might be a good idea, or just replace them as the labor cost will have been paid for at that point.
