Correct me if im wrong but a Bar is 14.7 psi ( atmospheric pressure at sea level )
1 bar = 14.503 psi.
14.7 is ~ one atm, and its also the stoichiometric afr for gasoline, but really, we're just splitting hairs between 14.5 and 14.7.

OK now the next obvious question ... who make a good high in ZDDP oil ? Synthetic of course
I am using AMSOIL Dominator 15W50 Racing Oil which has good levels of ZDDP.

Zinc Level 1424 ppm
Phosphorus 1575 ppm

Amsoil is good oil, I use Mobil 1 20w 50 for performance cars, I use Redline 10w 40in my 964. Both have high levels of ZDDP. Plenty of good choices out there.
