Oil sludge buildup and consumption - M112 and M113 - treatments?
Thought I would start a thread on this particular subject - M112 and M113 engines consuming oil, and that a portion of this consumption can be attributed to sludge build-up. The theory, if I have it right, is that using non-synthetic oil in early W210 cars and following the extended FSS intervals can result in sludge build-up, causing premature wear and/or oil consumption. Hence the successful O'Keefe lawsuit against MB on this very subject.
What I am wondering, and hopefully the pros can weigh in here, is what are the available treatments for sludge buildup? I'm in Canada, so the lawsuit doesn't apply here. I know that in the US, the dealer applies a consumption test and the process starts there. The dealer documents the consumption, will then see if the consumption is past a certain threshold, etc. and then and only then will MB step in, if all conditions are met. For those who either don't meet MB's criteria, or those who have been refused help, what options are there? I found this bit - Quote:
My E430 uses some oil. Approx. 2L in 4,600 Km or so (1L/2,300 Km). My tech just did the engine flush for me. Added Wynn's engine cleaner before the oil change, ran the car for 15 mins, and then changed the oil and filter, added Elf Solaris LSX 5W30 oil (MB 229.51). I will post whether or not this helps, but are there any other actions/tests that can be performed? TIA.

Also found this TSB on the subject - seems like MB will only step in once oil consumption has reached 1 quart/660 miles? That's about 1L/1060Km.

My indie suggested running Mobil Clean (dino I believe) and changing every 3-5,000 miles to clean the engine.

Mobil Delvac 1, every 5k miles. Pull the valve covers off after 30k miles and you will be able to eat off them.

these are known defects on those models, the only approach to rectify is to have engine flush every time a change oil is performed. Up to now it remains to be a mystery even to MB Germany. Hoping some one can come up with a better solution and why its happening.

how do they determine if proper maintainence has been done if the owner does his own maintainence? Are you unable to make a claim if you do all work on the car yourself?
