our 89 190e consumes quite a bit of oil and I have been curious. like jim's, no smoke, good compression.I suspected the valve guides, but no smoke at start up, it hasn't had any problems running. the plugs (which I just replaced) had a weird build up that I've never seen before. kind of a puffy black shiny crust, not the standard oily carbon residue I'm used to seeing on my bike or any cars I've ever had. could this help indicate some chronic problem these cars have?
