Diesel oils like Shell Rotella or Chevron Delo 400, both 15-40 weight, have a lot of good additives like ZDDP, if they are the "old" CI4+ spec, and do not also meet CJ. EPA has attacked diesels too, and the traps etc. that they now have do not like those additives. So, the CJ oil is decent but no where near as good as the older CI4+. APE "lets" the oil companies say their new oil is "backwards compatible" so the new stuff like the gold band "low emissions" Delo says CJ and CI4+. My local Chevron distributor still sells the "old" stuff in 5 gallon and larger containers.
