TBN & Noack for Some Mobil1 Oils

[Shel_B]

Does anyone have the TBN and Noack for:

M1 ESP 5W-30, 0W-30, and 0W20
M1 EP 5W-30, 0W20

Thanks for any help.

They don't typically publish NOACK info anymore, but the ESP should be less than 10% for Xw30 since they carry MB229.51 and MB229.52, and below 11% on 0W20 because VW 508/509 and MB229.71 limit the NOACK to 11%. If you really want to know, your best bet is to email technical support at XOM and see if they'll tell you, otherwise it's guesswork.

Thanks for the details on how to ferret out such information ... appreciate your help.

TBN:

EP 0W20: 7.0 (D4739)
EP HM 5W30: 7.4 (D4739) Assume non-HM is the same or slightly better.

This, to me, proves that starting noack is no indication of how “good” an oil is or how long it could be run out for an oci. Chevron supreme shares a similar/higher Noack yet Mobil 1 EP has been seen multiple times to exceed 15k easily in uoas.

Don't you mean TBN?

Noack:

M1 ESP 5W-30: couldn't find any number, but I remember it's 6.Xish %
M1 ESP 0W-30: 9.1/9.2 %
M1 ESP 0W-20: 11.2 %

btw, recent M1 ESP Formula 5W-30: 5.6 %

All numbers from several Russian VOAs.

Has like 9 actual approvals before the “recommended “ even starts

Recently changed the Castrol Magnatec 5w30 ~3.0 HTHS to Shell Helix Ultra 5W30 ~3.5 HTHS.
The car is certainly running smoother than the weird smelling castrol.
Noack circa 5%
