Do you have the 2.4 4cyl engine. These engines were known for premature ring wear leading to high oil consumption. I had the pistons, rings, and timing chain replaced on my 2013 Equinox with 42k miles in March 2016. There is a class action suit for this problem, I’m not sure of the status or if your car is covered.
1 qt/3000 miles is not bad for this engine, just keep an eye on the oil level and change the oil every 5k miles.
