OM642 Longevity





if it was a gas engine I would fill each cylinder with solvent. Let it sit and then turn it over slowly a few times.
I don't know what to do with a diesel.
Guess you could do about the same, but would have to pull the injectors or glow plugs.
And I understand that also has risks.








You only use the RESTORE for one oil change every 100K miles. I don’t think that will hurt any of the items mentioned above.

I added oil only once.
We have owners on Sprinter forum reporting >600,000 miles on those vehicles.

Valvoline has announced a new version of Restore being released in 2024,
Premium Blue Restore on Valvoline website
Another easier to find source of oil that will clean rings is from High Performance Lubricants (sold at their online store (Advance Lubrication Inc). Bob is the Oil Guy forum has many threads with photos and used oil analysis that show it does as claimed. They are made with high content of Ester and AN oils to clean the rings and everything else. They are not flushes and do not contain any solvents or harsh chemicals. I used their Euro 229.51/LL04 oil to clean deposits out of a BMW N52 I bought in one 5k mile OCI. Worked as advertised. All the brown crusty stuff was gone from the head and oil consumption is zero.

I have the Euro 5W-30 229,51 "compliant" HPL oil in my 2008 E320 OM642 currently. Does NOT need to be cleaned as at only 161k miles it still doesn't burn any oil with 5k OCIs (mostly annual changes) of Castrol C3 oil from new. I did change the CCV system components at 120k miles.

This conspiracy theory needs to go away.
Delo 400 XLE is listed on the truck approval sheets on the Mercedes Bevo list. Mercedes BEVO 228.51
I haven't tried it though because 229.5x is easy to find and doesn't cost more in my area.




Deli 400 is certainty approved for a lot more diesel engines than Mobil1 ESP3.
now that I an not on IL, I am not as worried about having a 0w oil.
Hello Jell-O. I do believe that bio-diesel in the mixtures are a part of the problem.
Mercedes addressed it,
I've come to believe there is no point in continuing argue with the non believers who buy a Mercedes then don't believe Mercedes bulletins and information sheets.
They're gonna do what they're gonna do.

MB never was proved to cheat on emissions. The Bluetec settlement is about not delivering what was promised and it is settlement, so nothing was proved, or admitted.
