2014 Outback 2.5 Premium with CVT, anyone having issues with burning oil?

We've made the oil changes per the manual's recommendations, and are using the synthetic oil, yet we seem to be down at least a quart every 2000 miles or so, not something I was expecting with a vehicle we purchased new less than 2 years ago. We now have about 21,000 miles on the vehicle--quite disappointing for a company that brags about its environmental values...

Consumer Reports had an article about it recently:

Is anyone else having this issue and has Subaru offered any fixes?

    if you use engine-braking, consider to stop doing that so much. It's bad to always be downshifting 3,2,1 and using engine to slow the vehicle - it consumes clutch and can consume oil.
    with some engines oil can be consumed via high-rpm deceleration due to negative crankcase pressure - the oil is not burned - it goes out the exhaust unburned.
    racers and other motorheads sometimes install 'catch-cans' to capture this oil before it goes into the intake, and for proper disposal. you may find an oil-catch-can is available/useful for your vehicle.

    Some users are experiencing oil burning with this FB25 engine, especially with manual transmissions. Subaru considers 1 quart per 1,200 miles to be acceptable. Some say using a slightly different oil, such as 5w-20 will help, others say no difference. I have same engine on my 2012 Forester and average 1 quart between oil changes(6k miles) in mixed driving. I do notice with all highway driving(65-70 mph) with my non-CVT transmission, averaging 1 quart per 3k miles. In my case seem to be rpm related, more higher rpm(2500-2600rpm on highway), more oil consumed.

    Our son had a 2009 Impreza that started burning oil at the rate of a quart every 300-500 miles when it hit 30,000 miles. The dealer was in the process of doing an oil consumption test when the car decided to throw a rod one dark rainy night at 32,000 miles.

    The Service Manager hinted that this wasn't unusual.

    The latest issue of Consumer's Reports talks about Subarus using oil.
