The deal is that something probably isn't working properly in the engine if it's burning oil, and that may well get worse over time. Oil consumption may not be unusual if you're using high RPMs all the time, but our Forester has barely used a drop in the two years we've had it, and I suspect the 4mm drop we did see on the dipstick after one highway trip was just fuel and water accumulated over the winter boiling off. So the FB engines really shouldn't burn oil in normal driving.
The real problem is that it seems some of the FB engines do burn oil and others don't, and I don't know of any way to tell which is which on a test-drive. You may need to drive it a thousand miles to be sure of which you've got.
On the plus side, a 2013 will presumably still have engine warranty for a couple of years, so, if the consumption is bad, you should be able to get a new short block. But that's still going to take the car out of your hands for a week, even if you don't have to badger them to replace it.
