Ok we have established that one of the lowest, if not the lowest NOACK oils is Amsoil ASF 10w-40 at 3.7. So would that not be a great oil for vehicles that are consuming lower NOACK oils? Costs a bit more than others but...
If it's already burning lower NOACK oils, it's not a matter of time at temperature under load. It's a mechanical issue that either needs to be repaired, or dealt with to minimize catalyst burning.

NOACK is important if it is the lighter fractions of the oil that are being burned off. If you have leaking valve stem seals or stuck rings, it isn't going to help.
Agreed w all above comments. If it is machanical then fix that. but it seems lately that post are being made regarding this and there R lots of people suggesting to run this oils and that oil,stating “low” NOACK level of 7+ Or HM oils like it was a cure. Just sayin’ a NOACK level of 4 or less would easily trump this don’t U agree.
