They did, because all the turbo engines were blowing up, especially the V8 ones(n63) with turbos inside. Even the I6(n54) Can barely make it 80K with 15K intervals.

Magnesium is way too high to be residual. There have been recent UOA's of M1 0w40 and they don't look like this.

I haven't seen a super recent VOA, so it's likely they are using magnesium now or its leftovers from previous fill.

I can't recall for sure if this was the SN formula of 0w40 or if it were some leftover SM formula that was still kicking around up here.

Was it changed based on time or BMW's CBS OLM?

I lurk tons of BMW forums, blogs and sites and i dont know how you came up with this conclusion.
Never heard of a turbo blowing up.

The M1 0w40 claims to have "exceptional cleaning abilities" so it maybe cleaning up from previous oils used.

"Mobil 1 0W-40 is made with a proprietary blend of ultra high performance synthetic basestocks fortified with a precisely balanced component system.

Provides excellent overall performance
Has excellent low temperature capabilities for rapid engine protection at start-up
Has enhanced frictional properties that aids fuel economy
Delivers fast protection for reduced engine wear and deposits even in the most extreme driving conditions
Provides exceptional cleaning power for dirty engines.

It ended up being both actually. I had set myself a one year time limit, but the countdown had reached just 1900km to go anyways (it starts at 26,000km!)

 

[Pontual]

My Citroen C5 Owner's Manual calls 18k Miles OCI in Europe and 15k kms (9ish k miles) in Brazil, both using fully syn Total Quarts 9000 5w30 ... (Haynes recommends miserable 6k miles for it, a third). Same oil. Reason, different fuels? We run pretty good gas in here with very low (max. 50ppm legally) of sulphur, but with 27% ethanol witch doesn't hurt oil at all, when not short tripped ...

Still don't get it.

Patman, did you change the oil yourself?

Viscosity of 131 at 40C is insane for M1 0W40, boron and magnesium count are also off. It all makes sense of course if you filled your car with SM version of the oil since most of the data I have is from SN. But if you bought your M1 in back 2014, it should be SN, and something is not right with your UOA.

 

[Noobie]

BMW's sold here are set to 12,000KMs here and as you all know, it varies depending on driving conditions. I always change it way before the OLM gets to 0.
My OCIs are 7.5KMs on synthethic oil and original filters for all my euro vehicles.

 

[Leonardo629]

Noobie, your sump is about 7qt.,so, IMHO you are dumping the oil way too early at around 5000mi. If you are using quality stuff like M1 0W40, I'd at least take the oil to 7500mi (12,000km), do an UOA and decide if pushing to 10,000mi is feasible for your driving habits. All in all it's your wallet.

Oops! I fixed it!

I'm a bit disappointed by this UOA here, but at the same time there is the possibility that the previous oil in there wasn't all that great (or was run for an even longer interval than this!), so this could possibly make the first interval with any oil look a bit worse than it should. I probably shouldn't have gone straight to a 1 year/15k run right off the bat either, I should have stopped it at about 8k to start and gone higher from there. But what's done is done and I'm not going to panic at this point. The wear numbers are nowhere near dangerous levels by any means. I still think M1 0w40 is a great value, I've bought a few 5 quart jugs of it now for under $24 when driving across the border to Niagara Falls, NY and I'll continue to do so for a while.


I've owned an 2003 M5 since it was new. Currently has 33,000 miles on it. I've been running German Castrol 0W-30 in it quite happily with yearly changes since 2005. Prior to switching to Castrol I ran M1 0W-40 oil in the car. It was good oil but engine noise was more apparent with the M1 oil in it. The oil analysis results I got back when running this oil were great but iron numbers were a little high. I believe Mobil has some iron source that M1 is being exposed to when they formulate it as I've never seen a M1 analysis that did have higher iron reported.

Cant do any UOA here since there are no labs that does that here.
I use Shell Helix Ultra 5W-40 and usually by the time it gets to 7.5K KMs according to the on board trip computer, it has over around 500 hours of operation with an avg speed of 15Km/h. Its driven in mostly heavy traffic and stop and go conditions.

Still, what you say could definitely be true. Hahahaha
If i push the OCI to the full 12K KMs the OCI would be around 18 months with over 800 hours of operation i'd guess.

I did change the oil myself, yes.

As far as 0w40 still being SM in 2014, keep in mind that in Canada our supply of 0w40 was still the SM formula for a very long time after you guys in the US got the SN version.

 

[chrisri]

How does API norm matter with this M1 0w40? Any A3/B4 can be approved for latest API norm in grade 40 or over. I'm sure M1 0w40 is exactly the same in SM and SN form.

 

[Garak]

There actually was a reformulation between North American SM and SN versions of M1 0w-40. Of course, the API certifications are really irrelevant on the product, but there were changes, and we got stuck with the old stock for a very long time up here. Yet, when knew Mobil HDEO stuff is out, look out, the old stuff is gone in minutes.

No, there were a lot of changes (and have been further changes) in M1 0w-40 and the formula changed between SM and SN.

 

[chrisri]

Maybe change in formulation was simply change from A3/B4-08 to-12, and API update was coincidence. Of course I'm only speculating, and it doesn't really matter..

No, the actual physical properties of the oil changed... HT/HS, VI, pour point, etc.

When it comes to the actual paperwork side of things, that's certainly possible. Maybe they updated everything at once. Mobil does that a lot. When CI-4+ was phased out in favour of CJ-4 here, Imperial Oil (our Exxon-Mobil) took that opportunity to get rid of all the Esso HDEOs and consolidate them with the Mobil line. The same occurred at either the end of SL or SM (I forget which) when it came to our Esso gasoline engine oils.

So, there were a whack of reformulations, relabelling, and repackaging going on all at once.
