I really like Outbacks, the styling, the features, and the value, but Subaru has not been on top of their game with engines. EJ25 had head gasket problem that has never been completely fixed. If I recall correctly Subaru redesigned the gasket a bit to make it "better", but it couldn't fix it completely. A buddy of mine with 2011 EJ25 Forester had to have his head gasket replaced under warranty in 2013. IMO that's insane to need head gasket replaced after two years of ownership. And now the new FB25 engines consume too much oil. The problem is fairly wide spread and Subaru forums are full of suggestions on how to properly break in the engine to minimize oil consumption after it's been broken in.
But back on topic, no, new engines with minimal mileage should not be consuming any significant amount of oil at all after the initial break in. It might be acceptable for an older car that is close to its end of expected operating life, but not for a new car. Subaru suggested oil change interval is 7000 miles. What's the point in even having suggested change interval period if you have to top the oil twice in that period? That is insane. As SparkyJJO has said above, oil burning on a new car means the oil is getting into combustion chamber, it should not be doing that on a new car. On an older car, maybe, but not on a new one. The oil burning is only going to get worse as the car ages. If the new car is burning oil at 1Qt or more every 6000 miles I shudder to think how bad it's going to be when the car is at 50-75K and is out of warranty.
I'm nowhere near having to replace my car yet, as it's only 10 years old and still drives just fine. However, every so often I look at the current crop of cars, and at Outback in particular. As I said, I like the car a lot, but the persistent engine issues make me weary. I would hope the Subaru manages to fix them in 3-5 years when it's time for me to buy a new car, but I'm skeptical they will given the fact that they've never managed to fix EJ25.
