Acceptable oil consumption for your vehicle is 1 quart in 2000 miles. If you are changing the oil yourself, and know that it starts at the full mark, this will give an indication of the rate. If there are no external leaks to consider, and the usage is more than accepted, I would have a piston/ring cleaning procedure performed. You show to be only putting about 15k miles on it a year, and I don't know your driving habits. In most cases, the rings can get stuck from carbon, and allow more oil to get into the combustion chamber, and you will not notice excessive smoke.
