I appoligize if this was incorrect information out of "text" to your post, I had replied to another post about "which oils are the equivalent to use in our trucks other than listed on the dash plates" I replied and got the message "no correct link contact supervisor" (??) I had to log in again and lo, my answer to that post (which has now mysteriously disappeared!) Appeared in your post and request. Any way after all that rant, my answer seems to fit, It is all in the T.M.s but hope it helps you.
