Oil sludge buildup and consumption - M112 and M113 - treatments?

[Zeus]

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 -

I read another post by another tech stating the same thing.

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.
