Mobil 1 ESP X2 0W20 VOA

@BurntMusic
You did us the favor. No need to go above that as we are appreciative of the expenditure and share. ✌
The most i would do is ask BS to retest.

I've asked BS to look into the phosphorus value and asked them about the KV 100°C value yesterday. I haven't heard back but they are pretty quick to respond. I'll update as I hear more. Thank you for the discussion!

I have received a response from Blackstone.

Thanks for your email.

I had the spectral exam rerun on this sample, and the phosphorus value did
come back a little lower than before at 822 ppm. (As with any sort of
scientific testing, there is a margin of error with our analysis).
Obviously that is still a little higher than the limit you provided, and if
the phosphorus content is a serious concern for you then maybe this Mobil 1
isn't the right pick. From our view, we still think this oil would perform
well.

I believe we do perform the same testing as Mobil 1 would on their oils.
I'm not sure what particular page you were looking at on their website, but
I found a Safety Data Sheet for the ESP X2 0W/20 oil, and it says they test
the viscosity according to the ASTM Method D 445, which is the same method
we adhere to in our lab. Even in virgin samples, though, there can be
variation in viscosity (and additive levels too for that matter) so I don't
think it's anything to be overly concerned by. The viscosity at 9.56 cSt
was still within the expected range for an unused 0W/20-grade oil.

Good looking oil, but the comments from Blackstone are awful.

"the viscosity is in spec for a 0w-20 oil"

KV100 is... 9.56 cSt... which is in 30 grade territory, not 20 grade. Not that that's a bad thing.

They also show the phosphorus high for an API SN oil, above the 800 ppm maximum. I'd ask them to rerun it to verify the results.

Hi all,

You can easily use Google to translate the test report)
The same level of elements but TBN=8.76 and KV100=8.04. So results are adequate for 0w-20 MB229.71 VW508/509.
I've heard that this is a factory fill oil for new Mercedes engines.
