Looking into trying Vavoline Maxlife 10w 30 or Castrol GTX High Mileage 10w 30 next OCI. Castrol for some reason doesn't show or will tell me NOACK for this oil. They show for Castrol GTX, Magnatec, etc...but not High Mileage. I called and they said they cannot tell. Anyone have any ideas?

Blenders have been really riding the NOACK spec in the past few years, wouldn't be surprised to see lower volatility on the newest formulas

Thanks. They post NOACK for their other 10w 30 accept High Mileage. Just was curious if anyone knew why. Have a great weekend.
