Whos running Mobil 1 0w-40?

64.3 cSt is not "low 30s". There are ACEA A3/B4 oils that have that viscosity or even lower.

It didn't appear to hurt anything, so I would not be concerned.

Its lower than the "values should be"...I just wondered if they put the right oil in.

Oil gurus, here is my second report after 7700 miles. This time around I had both TAN and TBN analyzed. The first report was on 10w60, the second is on 0w40 Mobil 1. My usage/commute is roughly 50:50.

My TAN was higher than TBN at 7700miles yet BS is suggesting I try 9000miles on my current fill?

It does follow the pattern of rising iron content after a switch to Mobil 1.

I wonder what the clearances for the cam/ledger bearings are for the S65. I notice rising iron in many of the thinner oil class analysis as well.

All they're saying is that it's slightly out-of-grade. It's nothing to worry about, in my opinion. There are production variances in the blending anyway, and he could've just gotten a slightly-thinner-than-normal bottle to begin with.

The report looks fine other than that so I see no reason to do anything different. Just my two cents.

You think their quality control might be that poor?
I would have thought it highly unlikely - people in white coats are paid to check that the end product stays within spec.

There are always production variances and it's not something they're going to reveal. All of those ISO/QS certifications allow for it. Even Blackstone has a margin of error. If you're bored/curious, buy a bunch of bottles of the same oil (with different lot numbers) and send them in for VOAs. You'll see a range of values.

Ordinarily, when you buy chemical or obtain a sample of a chemical from a manufacturer, they will include a certificate of analysis that lists various control parameters, and how they stack up against the required minimum values. So for example, it will say, "analysis: 25.2% solids, specification: 24-26% solids." In the absence of that kind of information, there's really no recourse that consumers have. Heck, even Lubrizol, the primary supplier of oils and additives, has huge ranges for what they sell. Science...is not always an exact science.

Since there are no apparent negative effects, it's not worth losing sleep over.

Well I have to disagree...having worked quality control in various industries the very least a product must do is match its spec. If you are selling a 40W oil then it will be a 40W oil. Before final packaging (of a production run of 100,000s of gallons of oil) it will be someones job to take a sample and make sure it matches what it says on the label, in this case it will be that it is a 40W oil (and that it is in within all the other specs included on the labeling). The exposure by not doing so could be extensive.

If I didn't see the Mobil 1 going in myself then I would have a doubt at the back of my mind that they put something else in given its viscosity after only 1000 miles. Most every other Mobil 1 analysis has it in range after many more miles.

Maybe its just me but that second report didnt look that great compared to the previous TWS. Thats the first time I have seen lead values increase when switching from TWS to 0w40. As someone else noted, the increase in iron seems to be a trend with lighter grade oils.

The only thing we don't know is what kind of tolerances are allowed. Maybe they are allowed 41W, or 39.5W. Who knows?

(I also work in quality assurance FYI).

+1. I think I've looked at every M1 analysis, and I don't think I've ever seen lead go up. For what it's worth, mine went from 9 to 3 (using same interval of 5000 miles. If driven hard, the iron does go up, but mine was still around average so I didn't worry much.

I don't how your market works, but in the UK whatever is on the label has to be what is in the package. If it wasn't you would be liable for any consequential damage.
My point really was that the viscosity for that 1000 mile sample was unusually low for a 0W40 oil - could a tolerance of ~1 make that sort of difference? Bear in mind that it was also supposedly mixed with an amount of 10W60 from the oil cooler and lines.

Didn't look at that post to be honest. I was just saying that there is such thing as tolerances. Whether it's 0.5, 1, 3W, who knows?

Look at the whole S55 power debate. Engine rated at 425hp, but it's putting out more. Unless we know what the tolerance for Mobil1 0W40 is, there's no way you can say that if you buy 40W, you'll get EXACTLY 40W for 100% sure. And I think that's what dparm was saying too.

Anyway carry on

FWIW, I had the first report done after roughly 3000 miles of purchase. I suspected the oil had been changed prior given it's color when I drained it: the 5000 miles was just my estimate. There is no doubt, however, with the mileage on the second report.

Will do another reading around December on the current M1 fill. If no improvement, I know what I will be using my tax refund for.

does it rhyme with "fairings facement"?

Unbelievable- the excruciatingly detailed blather and then the dismissive justification. Not necessarily directed at those quoted here ...
If the shoe fits wear it

Has it not occurred to anyone the iron is from crank bedplate iron inserts. But don't worry Mobil 1 QC will get you at least a 30 weight in that bottle of 0w40. You're joking.
My platinum tech has seen crank main bearings give in more than rod bearings, and he mentioned the turbo engines too ...
No one changes their oil anymore he said (lease cars) and it's the easiest thing to do. If you would see any proper sign of a good S65 break in, it would be tin from the running in layer on the pistons. ....but lead, iron, silicon from sand casting? BS - are initials, right? LOL

i agree it is true how most ppl these days dont change the oil on their leased vehicle.

I am just a DIYer so I don't have a super platinum tech to trump your platinum tech, but this is the first I have read that there is a crank bearing problem on these motors that is worse than the rod bearing problem.

Camshafts too.

[dparm]

The "40" portion is a range of values anyway. Mobil does publish the "typical" value on the website, but it's not going to be perfect every time. As I suggested, buy a bunch of bottles and pay for VOAs. Prove me wrong.

The main bearing problem is not in the s65, it is a problem with newer cars with the stop/start feature. Many cars in our dealerships with short blocks replaced with mains knocked out.
