Based on the oxidation value and the additives (Calcium too low for one) I'd say this is the SP version. Virgin oxidation for SN was ~30, for SP it is ~7. Your used oxidation of 12 points to it being SP.I'm nearly positive its SL.
That is higher than virgin SN or SP version of M1 0W40, so I'm guessing it's carryover from a previous oil that did have a high amount of Boron. Either that or maybe an additive that increased the Boron?A good chunk of Boron in this oil at 453.
Interesting turn here about the boron. 145 sounds like more of what we see in oil. So, I'd say what @buster posted was correct and somethings not right at 453.Like a couple have mentioned, the Boron is way too high. It makes no sense. Also, the Magnesium should be higher if it was the SP. It *looks* more like SP than SN, but it still has enough difference from SP that it's kind of a mystery.
OP: did you put any additives in this oil, or the previous oil change?
Another possibility is that the M1 0W40 SP VOA that buster linked above is wrong. After all, the person who posted that never posted the actual report. They just posted a partial report, typed in manually. They could've typo-ed when posting.
That's weird, OAI wants you to do a baseline sample so that things that might otherwise be flagged won't be, due to the VOA values being known. Oxidation is an example.I never put any additives in any of my vehicles and no one but my bride has access to it and she would not add anything either, atleast not without express written permission.
I don’t put a ton of stock in voas as I’ve had them come back wildly different. I recall a VTwin uoa that came back at like 1800 zinc and my voa was 1400 ish… I talked to Blackstone about it and they explained why their system really isn’t great for VOA and it made sense but I can’t re-explain it.
Well, i guess i'm assuming they already have this oil?That's weird, OAI wants you to do a baseline sample so that things that might otherwise be flagged won't be, due to the VOA values being known. Oxidation is an example.
Yeah, I'd ask for a re-test, the Calcium and Magnesium levels don't look right, nor does the Boron as others have pointed out. Phosphorous and Zinc are also high.Well, i guess i'm assuming they already have this oil?
I guess next time around i can send a virgin sample. I suppose i could e-mail them and ask for a retest, too. since I'm not holding my breath for the Blackstone result before they toss this one at OAI.
