Toyota 0W-20 SN_2012 Elantra_7,608 mi._51,272 mi.

These are both from the same stash of oil, wonder why the difference in the moly, but looks good, right?

Silicon is a bit high but might not be dirt. looks like you could do 10k tbn is 3.7

 

[donnyj08]

looks pretty good to me.

 

[buster]

Looks great.

Were the two bulk oil purchases on the same date? I wonder if moly is subject to settling out or quality control is lacking at Mobil.

 

[gpshumway]

Is the "bulk" version of this oil supposed to be the same as the TGMO available in quarts? I thought the SN version still had ~300ppm of Moly.

I recd the results of the Toyota 0W20 SN Synthetic Oil VOA this morning. It is posted below:
Iron 0.7

Silicon 5.7
Potassium 0.0

Phosphorus 906 Was 687
Sulfur 3489 Was 3258
Zinc 910 Was 710
Visc@40C 37.38 Was 38.2
Visc@100C 8.54 Was 8.85-9.3-9.7 depending on the lab
VI 216 Was 214
TBN 6.84 wAS 7.0

There have obviously been some changes informulation from the SM formulation, specifically Moly, Zinc and Phosphorus, but it looks like the Toyota 0W20 SN formulation continues to maintain it's very high VI unlike so many other SN formulations.

Yes. I used the last of it in my wife's car and on this change I dumped in from quart bottles I had. So the next UOA I post will be from the bottles. Then back to the bulk which I just scored again.

The lower moly could be a lab error.
Some lab's have difficulty measuring it accurately.

BTW, why no test for lead?

My bad.
Speaking of which, is it acceptable to import an image from the lab these days? I have a .pdf from WIX which, if I knew how and it is acceptable, would be so much more convenient to use.

You would have to take a screenshot of the pdf and covert it to an image file. Post the image to a photo album account online, link the photo from the account.
