I bought my very first new
I bought my very first new car, a 2014 manual Outback, in April and began having these same oil consumption issues with just 1200 miles on the car. My dealership did one oil consumption test and all seemed fine. Until it wasn't. The more mileage on the car, the more oil it seemed to use. The good news: my dealership replaced the engine block rather than just the rings. The bad news: I've put 3000 miles on the new engine and it's consuming oil, too. When the low oil consumption light came on again, I was 1.5 quarts low.
Now I'm waiting to hear back from the dealership. If it weren't for this issue, I'd be crazy in love with this car, but this problem is really a deal breaker. Wish I'd known about it before I decided to buy. So sad that Subaru never figured out how to fix this problem.
