I have a 06 impreza 2.5rs. I got it band new in may. It now has 12k on the clock. I broke it in right changed the oil at 500 then at 1500 thats when I switched to valvolen synpro. Is it normal for the 2.5 to use 1qt of oil in 3000 miles? I drive the car hard some times, other then that I drive the free way. I would like to know if any one is having this same prob. or if I should take it back to the stealership.
