Extended Drain Oil for MB 229.5 applications

[edyvw]

Mercedes Benz does not have problems with high saps oils used in their DI engines. They offer the best engine protection - in 229.5, engine protection takes precedence over exhaust treatment equipment protection.

No it doesn’t. MB229.5 doesn’t have LSPI test and all current engines use MB229.51/52 if FE oils are not satisfactory like MB229.71 and MB229.61.
Also, yes MB also has CBU issues.

This is OLOA 54720's instruction，It reveals the ability of the Mercedes MB229.71 standard to protect against LSPI，Opel OV0401547 too。

I know that Opel's standard must have used GM's LSPI engine test procedures, ACEA C6 and A7/B7, API SN PLUS and SP/ILASCGF-6 for Ford LSPI engine test procedures。

But I'm not sure if Mercedes developed its own LSPI engine test, and I'm not sure if it used GM's program or Ford's program

MB as far as I understand from Lubrizol has its own LSPI test.

An older Afton handbook states that MB 229.71 has LSPI test: Daimler LSPI engine test (Daimler inhouse test).

An older Afton handbook states that MB 229.71 has LSPI test: Daimler LSPI engine test (Daimler inhouse test).

The LSPI test applies to 229.3, 229.31, 229.5, 229.51, 229.52, 229.6, 229.71, however the limits hadn't been decided yet with the 2016.1 release:

So all this means is that they were requiring the test to be done and results to be reported but they didn't set any limits.

As of the time that paper was written, yes.

The document of oloa 54720 in 2020 shows that Jaguar's JLR stjlr 03-5006-16 has lspi protection.

Yes, I expect more OEM's will add their own LSPI testing if necessary.

Not in their v6's. Maybe the turbo 4's but I haven't heard of any in those.

They do have "issues." Same like BMW N55 and newer engines do. There is some CBU, but absolutely does not affect performance as they know how to make PCV.

What I wonder, how can an ( 229.5) A3 oil such as the mobile 1 fs 0W40 with 3500ppm calcium pass the LSPi test?

It doesn't because it's not SN+ or SP.

LSPI is only a concern for some engine families anyways.
