Just a heads-up on the latest diesel oils... the new CK rating may also mean further reduced ZDDP levels, to allow compatibility with the newer diesels that have soot particulate filters. CJ ratings were better (generally more ZDDP than CK), and from memory you have to go back to CI or CF to get the really good stuff.
Reduced ZDDP oil should not be a serious issue for the M119, but you would never want to use a low-ZDDP oil on the M117!
Be careful out there. Not all "diesel" oil is the same, and the newest stuff may not be good for old motors.
