So after 105,000 miles the Subaru is finally consuming 1/2qt or so every 1000 miles. I'm now trying 1qt of MMO in the sump as an oil additive for the next 1000 mile interval before my oil change to see if it helps some of the consumption. I will use this thread to report back as time goes forward on the progress.
Anyone have any good stories though about MMO helping their oil consumption? I am hoping to clean up any sticky oil control rings.
