Geographic location can be a huge consideration also. My truck needs would differ greatly if I were back in SoDak over western AZ where I’ve been stuck for 20 years +.
Agree. 2007 CTD 295k. I had to make adjustments when we moved to Mesa from south central Washington. I found that I needed more frequent tire rotations due to the extream temps in the Summer. Also, more frequent oil changes May through September. However I’m still running 15/40 Amsoil. I also fully service my tranny once a year wether it needs it or not.
