2025 BMW M340i, factory fill, 1k mi

[mattsheng]

Just did a break-in oil change at 1k miles and sent the factory fill oil & a virgin sample of LL22FE++ for oil analyses. Quite a surprise to see that LL22FE++ has high Calcium content. Isn't BMW worried about LSPI, since this oil is also recommended for Gen 3 B48?

Gen 3 B58 in the US now comes with GPF, so LL01 and LL01FE are no longer an option. LL17FE+ and LL12FE are still technically suitable per BMW TIS. Should I stick with LL22FE++ or go with LL17FE+ or LL12FE during the warranty period?

Factory fill analysis:

Virgin LL22FE++:

Viscosity seems very low. Everything else looks normal. Ca isn't that high at 1,874ppm.

Do they make an approved 20 grade oil? That stuff is quite thin w/the fuel.

LL17FE+ (0w20) is approved for this engine, at least in BMW technical document, but not on the owner's manual.

Try to find a 0w-20.

Well yeah, it is 0W12.

LSPI doesn’t affect all engines. It is generally trait of Asian and American small turbo engines.
No European engine currently or in the last 15yrs had LSPI issue.

As for other alternatives, LL04 is thick LL17FE or LL22.

Currently BMW doesn't test for LSPI. LSPI is a problem related to engine tuning by the automaker not TGDI by itself.

As for your UOA there's a bunch of Moly in that factory fill and dealer oil. Wow!

Interesting to see how important boundary lubrication is with this ultra low viscosity oils.

Why why why do people insist on wasting money on oil analysis?
Seriously doesn't need to be done ,especially on brand new vehicles
Change it early and often and you'll be fine

Curiosity and a desire to contribute to the BITOG community. New car owners want to scratch that itch.

UOA can pin point to coming issues (certain wear metals indicating failing, for example, rod bearings). Intrusion of coolant, failing injectors etc.
New vehicles are different story, especially with 1000mls.

I get all that, I guess I want someone to say getting the analysis saved their engine, all I hear is how good the analysis is
Hell if you change oil early and often , don't overheat the engine and drive sensible, your good

Not really. UOA is good determinant of proper OCI. Some oils get obliterated by engine. Engines don’t implode bcs. bad oil. They die slow death.
