How they bumped the zinc and magnesium up while adding moly and boron. Phosphorous is still there strong...I'd say they definitely did their optimization work with this additive pack. Makes me want to pry and find out what ashless AW additives are in the mix as well! Looking forward to seeing a long term UOA on this in a real tough EGR (>30%) DPF regen application.

grin Thanks much for this post, it was very helpful. Had a sample flagged as bad, and it looks like they accidentally compared to the old version DEO.
