I had two EA888 gen3. Golf gti mk7 (2014 prod) and then Audi A5 second generation (2017 prod). In both I changed PCV (BL code an the end) to the latest revision and it absolutely didn’t help. Golf was tuned, Audi not and both engines died like clockwork through oil consumption.
Never heard of excessive oil consumption on EA888 third gen engines but
of course I don't question your personal experiences.
However the point is, what has it got to do with SAPS levels? Forum talk?
Hearsay?
In golf I used motul specific 5W30 504/507, in Audi - Castrol edge 5W30 So I don’t really trust this kinda ecological low saps oils.
I doubt that these oils, if VW 504 00 approved (507 00 only matters for Diesel
engines), were to blame for consumption issues. VW 504 00 isn't even low SAPS,
it's more of a mid SAPS actually. That said, there are indeed better VW 504 00
oils available, specifically M1 ESP 5W-30 and Ravenol VMP 5W-30 to name two
of them. Higher flashpoints, lower Noack losses which should to some extent
result in lower oil consumption
IF there's nothing wrong with piston rings or
PCV. Raised SAPS levels won't help with engine issues on such cars anyway.
Higher flashpoints and lower Noack losses at least potentially would.
After signing contract with shell, bmw no longer provides approvals to other oils, so I think it’s just money and marketing.
And if you know is there any changes in Mobil1 new life 0w40 and current Mobil 1 FS 0w40?
Honestly, this is just ridiculous. There is no relation between approvals and
supplier contracts. ANY blender will get the desired BMW approval if they
meet the requirements. There is no 'exclusive' contract existing except Shell
provides some engine oil to BMW. At least some of BMW's transmission oils
are still supplied by BP/Castrol.
