My 2005 Subaru impreza wrx sti has been losing oil at a rate of ~2 qts per 1000 miles since the day it was purchased with 37 miles. I have taken it in to a Subaru dealership seven times. The dealership can not find the source of the problem, though, after two oil consumption tests, they can confirm that the car loses oil at an abnormal rate.
