The brands (Rotella, Motorcraft, Cononcco Phillips, Valvoline) I listed earlier in the 15W40 version did not reduce anti wear additives and in some cases these additive were increased.
For our trucks, the normal oil is 10W-30. 15W-40 is for temperatures above 20 degrees. I see temperatures below zero at times so there are few options left.
