Oil consumption with 6.6 turbo Duramax??

Adding the 10 quarts each time means that you are using the oil. If you added only 8 quarts, it could mean that there were 2 quarts that stayed in the engine when you drained it.
I think you will find that some of the oil is in fact getting burned, and going out the exhaust. Not so noticeable, that you're seeing the tell-tale smoke, but a little going through the Turbo would get heated and blow out the tailpipe without notice.....figure a few drops per 100 miles, and you're gonna probably have a quart when you do the oil change.
I have a Honda Fit....it is driven 90% highway miles (600-700 miles at a clip), and I find that I have to add oil (maybe 1/4 quart) every 1000 miles. I didn't have to do this with my old Civic, but this engine takes a lighter oil, so I figured that was part of the problem....but, it could also be the newer anti-smog parts that are on this engine??
If the engine is running well, and you feel that the performance is what you wanted, I don't know if I'd get too upset by this oil use.
But, as mentioned, you should be checking the level between oil changes....and I'm curious as to where the oil was on the dipstick prior to the last oil change?
Hey, Maybe the engine thinks it's a two-cycle:B
