Shell Rotella T or Mobil DelVac, either in SAE15W-40 is my choice as well. If you can, get the now discontinued formula with the higher ZDDP levels; it's identified by having an API rating of CI-4 or CI-4+. Though it's been out of manufacture for some time now, I run across it frequently at the smaller auto parts stores. The additive package has been reduced in the current (CJ-4) formula due to catalytic converters on diesel trucks.
