80,000 km is about 50,000 miles? Its possible the engine is still breaking in, how long was the original fill oil in the engine?
How bad are the oil leaks? My 190D (OM601) has Mobil 1 5w40 and leaks a quart of oil in about 1,500 miles (so say 1 liter in ~2,400km) and is still improving. If you have more serious leaks might I suggest fixing them? I use Mobil 1 because I drive a lot and this way I only need to change the oil 2 or 3 times a year @ 15,000 mile intervals which my analysis supports. Marshall said that without a bypass oil filter you couldn't really do long change intervals on a 617 engine because the soot loading would get too high and I believe that. In my 240D I run Delvac 1300 because of that. Of course that car leaks a quart in ~200 miles because of bad oil cooler lines... -Curt Date: Sat, 25 Apr 2009 17:00:08 +0200 From: Peter Merle <merle.pe...@gmail.com> Subject: [MBZ] OIl Analysis - High Copper and Iron To: Mercedes Discussion List <mercedes@okiebenz.com> Message-ID: <2ea1fde20904250800vd534288ib0f291c680318...@mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" Did my first oil analysis on my Om617 300D. This engine I overhauled some 5 years and 80000 km ago ( I assembled all myself ) . After initial fill its run on Mobil 1 only . Oil analysis came up with high Copper - @ 29 ppm and Iron @ 71 ppm . Lab report said that this could possibly be pump wear ( Injector or oil - not sure ) . Oil had only done 1800 km since oil change . Any suggestions where to go from here. I'm keen to change to Dino oil as the oil leaks are driving me mad! ( My other 3 cars were all OK - OM617 *2 and Om603 - they are all on Dino oil ) Peter -------------- next part -------------- An HTML attachment was scrubbed...
