Your oil cartons come with cats too huh Bob 
? New DEO looks like it has all the making of a rock star.

VOA here if you wanna see the changes in additive levels over time.

So Bob, why did you switch? Run out of the old stuff and couldn't get any more? Do you really think the M1 0w40 will work as well? IMO there are three (3) Mobil products that are better: Delvac 1, M1 TDT, and M1 ESP Formula M. Maybe a fourth product if you count the ESP Formula 5w30 as a different product from the Formula M.

I saw that other thread after I posted here, where you showed the VOA results and asked for comments.
I do not think it is a bad oil, I just think Mobil makes better ones. But the 0w40 is widely available, and maybe it's an updated formulation. I wonder if there are older VOA's for comparison.

Exactly my point. they do different things. It is fallacious to try to rank oils for different applications. Low SAPS oils, diesel oils, and an oil optimized for European high performance engines can't be ranked against each other. Personally, I woulld not use them interchangeably in the same engine. As my sig points out I have 4 oil applications in 5 vehicles and I don't even think about trying to find one oil that will work best in all.
The "apples and oranges" thing.
Why use an oil designed for American larger diesel engines when there's an oil the mfg specifically approves (not knowing the 50x #, I don't know which one, but M1 0W40 meets a lot of them)?

Charlie, years of usage and data showing API oils perform very well in TDIs (and VW has blessed their usage in the older TDIs), the same or better than OEM spec oils due to greater additives, higher TBN and usually higher HT/HS. Look over my UOA history up to this point, all with Mobil or Amsoil truck 5w40s.

Truck 5w40s are much easier to obtain and can cost less.
If it was not for my change in commute, I would have stuck with an HDEO 5w40. I might even change back since many are thinner now at lower temp than before.

I do agree with much of what's been said, and if I could get some I might even be tempted to try an ACEA E6 oil like Delvac 1 LE 5W30 in our X5 35d

However what got me excited was essentially putting the ESP Formula oils in the same bin as 0W40 and TDT. The ESP oils are "de-additivized" specifically for emission system protection. Whatever ashless components replace the Ca/Mg detergents and Zn/P are somewhat of a fascinating mystery to all of us. Actually the E6 D1 LE is sort of a truck version of the C3 oils:
P<800ppm, ash <1% (rather than 0.8%). It must have something in it: Mercedes says it's OK for big OTR trucks with bypass filters or centrifuges for astounding kms - 100-160K km. It has a TBN of 12.6!!
But for the time being I wouldn't chance running an ESP car oil in a vehicle that has no need for it, like the 01 BMW; that one gets 0W40 (remember where I live, it is parked outdoors).

I know you are doing M1 0W-40 now, but you did buy the NEW 5W-40 DEO, or is my memory playing tricks? (I really want more examples of NEW DEO in TDI's, so I hoping you have the oil 
)
