My 2012 Outback with the H-6
My 2012 Outback with the H-6 engine has used 1/2 quart every 3000 miles since new. The first time the low oil light came on I was shocked because I had not owned a car that actually burned oil except for the well used junkers I would buy to act as the second car to my family. I have switched brands to try and make it go away. Synthetic burns a bit faster than dinosaur oil, and 10W40 burns slower than the 5W30. I am thinking of trying synthetic diesel oil because it contains zinc, which is I understand is good for maintaining high compression. I really love the car and its utilitarian comfort, however I won't buy another one until this problem is fixed. There is no reason for a 2000+ car to burn oil, but on the flip side it is really capable and comfortable and has never needed a repair with 63000 miles on it.
