I drive a 1999 s/w 2 with 66,000 miles on it ,when I first bought it it used One quart of oil every 900 miles so I heard about the mmo soak I tried that and now it uses a quart every 400 miles? what is up with that it made it much worse .Is there any thing I can do to stop this ? Is it new engine time? MMO Soak what a bunch of CRAP!!!!!!!!!!!!!!!!!!!!!!!!!!!
