For direct injection engines, Castrol would be probably a better fit. M1 0W40 packs a lot of SAPS.
Mobil 1 0w-40
- Thread starter Shel_B
- Start date
Left - new stock. Right - old stock. Possible change in formulation? I believe they're both API SN. Most importantly - still Porsche A40 rated.
I don't think Mobil has plans to significantly change the additive package in the Euro Full SAPS or 15W-50 oils, the calcium is way too high for SN+ or SP.
Posted the same question on 2 threads by mistake. Here's the info if anyone is interested or has an answer;
"Any difference between these two bottles? Mobil specs the pour point of the new one (left) as -60°C whereas old one (right) states -40°C on the bottle. Wondering if there's a significant reformulation, maybe more GTL base?"

think its error, dont know really why they messed that up... but the formula have more pao in it nowdays
Do not trust the msds pour points for mobil oils. Some of the mobil 1 lines have the pour point listed as 90 degrees celcius others 0 degrees celcius. Obviously those numbers are false. Trust their pds
So here's a history of my experience with Mobil 0w40:
About a decade ago Mobil was unquestionably to top dog for 0w40. Specifically recommended for my application (R35 GTR) as it was "engineered to work with the special plasma coated cylinder bores". Probably nonsense but it had just about every cert and every manufactures recommendation out there as well as a -54°C pour point as per the bottle.
Next revision the 100°C kinematic viscosity dropped a bit, the pour point was -40°C as per the bottle and for whatever reason Nissan no longer recommended it for the GTR. Motul made a Nismo Spec 0w40 they used instead. Perhaps this is all marketing.
Next revision it lost LL01 (granted arguably an irrelevant point). At that time Castrol began offering German made Euro 0w40, still had LL01 and a pour point of -57°C I believe. Also 100°C kinematic viscosity was a bit higher than the Mobil. So that became my go to for years.
Next Castrol began to make the 0w40 in Belgium, lost LL01 but I still gave it the nod over Mobil.
GTR has been running on a steady diet of my massive stock of German Castrol and will until its gone.
Other turbo cars in the garage have been using up my Belgium Castrol stockpile.
Now the latest Mobil advertised a pour point of -60°C so perhaps we're moving in a positive direction.
Canadian Tire is offering a great deal on the Mobil ($31.99 plus a $10 gift card - Until March 31st) but you'll mostly find they are blowing out the old stock of Mobil 0w40. The NASCAR branded -40°C version. Walmart is beginning to get the new Mobil and I was able to find a Canadian Tire that had the new Mobil in the back and the guy was nice enough to get me only those jugs.
Anyway cold start engine wear in Canadian winters probably the worst thing my motor experiences so I'm all for the new lower pour point.
Love to hear any other opinions about the latest formulation. Property Specs for the new formula attached.

Almost none of what you posted above is relevant. Cold start wear is not the issue, the oil still carries a 0W winter rating and will be pumpable down to a very low temperature, just as any other oil with a 0W rating. Pour point is not the determining factor in "cold start engine wear" anyway.
The loss of BMW Longlife-01 is not necessarily related to performance, and is this an approval you need? You're majoring on a bunch of stuff that isn't really what matters in that oil or any other for that matter.

No not really. What you're listing aren't specifications, they are typical values from a PDS. As far as I can see the specifications, approvals and licenses the oil carries is the same except for Longlife-01 which you note is irrelevant to you.
