Excessive oil consumption between oil changes is not just limited to Subaru.

Manufacturers are being pushed for better mileage and the move is toward light 0-W20 oil, low friction piston rings, long maintenance intervals, etc. Normally aspirated Subaru has a 7500 interval. VW has a 10k maintenance interval. With the oil control rings used in use today (low friction running face coating) almost every engine is going to need to be topped off.

Acura had just as big of a problem from 2009 to 2011. There was a class action law suit against Honda for the same issue. The issue is pushing the boundaries of engine technology to get better mileage. My girlfriend two years ago had Lexus rebuild the bottom end of an IS250 engine because "the piston rings weren't up to spec" as the dealer told her. It isn't just Subaru.

I've done the research. 2012 into 2014 was a big problem for Subaru - the running face coating on the rings wore out at 20k to 40k miles. They were replacing rings on affected engines but enough dealer mechanics were botching enough rebuilds and dealers complained that the builds took too many hours labor so Subaru just started shipping engines. Subaru dealers were overfilling crankcases so the car appeared to use less oil. The previous owner just had the oil changed at Subaru before I bought it and it was overfull.

Anyway, the issue was always highway miles, never around town. It was also mostly 2.5 engines, less so the 2.0 in my car. It The 2.0 uses thicker oil anyway so that helps and it has a more rigorous maintenance regimen. I have the balance of the 60k power train warranty and could conceivably go for an oil consumption test and get a new engine under warranty if it comes down to it. My power train warranty may have even been increased to 100k due to the lawsuit - I'm going to take the car to Subaru and chat with the service manager about the warranty next week.
