First time UOA. Appears good to me. Anything notable? I feel like I got my money's worth for this oil change. I also feel pretty safe going 2 full years and upto 14k, though I'll probably do one more OCI at 12k to confirm the data point. Plus I switched to M1 0w40, so I'd like to do an apples-apples on it vs. AMSOil as much as is possible.
Code:
ALLAN: No, you shouldn't have any problems leaving the oil in use for a year or
two. Even three or four years shouldn't be a problem, if the engine starts to see
even less use. Averages are based on about 7,600 miles on the oil, so you've run
this oil a little longer than average. Iron and copper are a bit elevated, but
certainly nothing too surprising turned up here, considering your longer run. The
viscosity was just a little low, but that's not a major concern. No contamination
was found and the TBN was fine at 1.9 (1.0 is considered low). Nice. Try up to
13,000 miles.

Nice report. Even at 48k your engine could still be breaking in a little, so I think Blackstone's advice to not worry about the Fe & Cu levels is valid. Looks like you used the Amsoil mid-SAPS AFL 5w-40, is that correct?

Yes, it's a Mercedes engine, the M272. Fortunately, it's with the redesigned balance shaft. Thanks for the link to your C300's UOA. On the oil, I'm not 100% certain, but this was spring 2013 and I'm pretty sure at the time I think "Euro" meant low SAPS. I think they've since changed the nomenclature to go to mid-SAPS and low-SAPS instead of whatever it was and "Euro." In any case, I do know it would have been one that meets the MB229.51 spec since the shop services a lot of diesel Sprinters and they used the oil they had on hand. I did have a question on when an oil drops grade. How is one determining that? I assume from the 210 deg viscosity? Is there a place that maps the measurements to viscosities? The other viscosity measure is at 100 deg, that's not the "W" weight is it? I though the W weight was measured at 0 deg C. Aside from how it's measured I suppose I wouldn't be too surprised if it's sheared down a grade. I've made a half dozen or so loaded trips up the mountains and high desert of eastern Oregon and Washington. From what I've seen indicated on other threads, that's probably why MB specs a 40 grade for these long OCI's, so it's still a 30 grade by drain time.

Fe is totally in line or better if you add 50% for the extra mileage. Cu I noticed as well and even adjusted for the extra mileage seems high. Not too worried, I'm sure it's within a std dev of typical, but will be something to watch. Thanks.

Well, I stand corrected on the SAPS. I went over to the AMSOil site to double-checked and the 5w40 is only a mid-SAPS. The low-SAPS is a 5w30. The invoice stated 5w40, so I have no doubt as to the weight. I also noticed AMSOil has a 5w40 for diesel engines. I think it's likely I got that instead of the 5w40 Euro, but I can't be certain. The invoice only stated the make and weight.

Sorry for drawing this out, but looking at the TBN, I'd have to guess it's the Euro after all. About the only difference between the two models of oil seems to be the starting TBN, 8.0 for the Euro vs 10.4 for the diesel. Since I ended somewhat low at 1.9, compared to a number of other 10k UOA's I've seen on M1 0w40 (also 10+ TBN IIRC), I'd think I'm probably starting lower, which would point to the 8.0.

Looking at the elementals this is AFL 5W-40. Which is the Mid SAPS as others here have surmised. This oil starts at 14 cSt. and a drop to 11 at 12K+ miles is pretty typical for this type of oil. Does this Sprinter have oil cooler or copper in the oil lines/fittings? Where and how did you buy the oil? In Portland as a PC you could have just ordered on line and picked up at the Amsoil DC.

Well, that is embarrassing. blush

That is embarrassing too! blush I looked right at them but was fixated on low vs. mid, and mid vs high just didn't register somehow. Also, thanks for clearing things up for me with the J300 tables.

I took it to Upscale Auto in Tualatin. I think AMSOil is their shop standard. Not sure how they decided between mid & full SAPS. Obviously there's no DPF, so I don't need 229.51 spec oil, 229.5 is fine. Oh yeah, no oil cooler. It's completely stock. The oil plug washer fell into the drain pan, it's copper. smirk

The W grades are measured at temperatures between -40C for a 0W, and -15C for a 25W. The 30 grade of high temperature viscosity runs from 9.3 to 12.5 centistokes, and the 40 grade runs from 12.5 to 16.3 centistokes. Since your viscosity started out in the 14's, it was a 40 grade when new, but since the UOA measured the viscosity at 11.0, it sheared down to 30 during use. What kind of rpm's does the engine turn on the highway?

Thanks. Yes, that's what I realized after spending some quality time with the J300 tables. smile IMO, the W specs are a little confusing to make an opinion from given there are two moving parts, both the temp and the viscosity measure. And they are both well below "normal" for most of the US. -40C? How about a month of daily starts at -10 to 0C, what then? Or a at most 6 starts per year at -10 and the better part of three months at ~10-15C?

About 3000 +/- 200. I forget exactly, but I think 2800 is about 60mph and 3200 is about 70mph. I usually drive 60-65mph and almost never at 70 or beyond.

Is your sig correct, it's a 3.5L gas engine? I thought they were all diesel.

Yep, it's gas. That's why I put it in asterix. Apparently they made a few. No idea why. I got this one because it was lingering unwanted on the dealer's lot, and he made me an offer I couldn't refuse.
