Mine's around 235K and seems the same as it's been the last several years.
Of course, I still use Dino oil. I'm right at 2 bar when idling and 4.5 or
so bar at highway speeds when fully warmed if the level is near top. I
have an oil pump gasket leak, so my level drops. I'm losing about a quart
every 6-700 miles.
