I have 6 month old 2012 Impreza - bought it new. It uses about a quart of oil (0-20W) every 2000 miles. The dealer says the warranty will address repairs only if its less than every 1200 miles and that oil usage is not unexpected for such a lightweight oil. I think this is hogwash. Subaru specified this oil to improve mileage so that its fleet can meet federal gas mileage guidelines. It sounds like it is unable to properly seal such a low viscosity liquid. I have seen several posts about the existance of this problem
Comments welcome on both the issue and recommended course of action.
Thanks so much
