As a technician, I see no problem with your oil consumption. Since I see very few brand new cars I am not an expert on your question.
Just thought I would pass along a little tale I heard recently. Seems a little old lady brought in her Toyota at 110,000 miles with the engine locked up. She apologized that she had run past her advertised 100,000 mile service. She had done no service of any kind in 110,000 miles because she was told it didn't need servicing till 100,000mi. The story is that she drove the car on the original fill of oil till failure.
If this piece of American Folklore is true she had very little oil consumption.
