My 2019 Crosstrek (gas engine, 6 speed manual) consumes about a quart of oil if I drive it 1000 miles on the interstate. I broke in the engine very carefully. New cars shouldn't do this. I just switched from 5W 20 to 10W 30 to see if it will help. I'll let you know. I'm reading that I'm not the only one who's experienced this. Next purchase may be a Hyundai.
