Zinc content in mineral motor oil


Hooking up on to this thread, I´ve yesterday sent a querry to Shell of Sweden (where I´m based) regarding the zinc contents in Shell´s Helix Super 10-40 mineral oil (still in the market here), which I guess is the closiest match to the propper motor oil for our cars recomended in the car´s manual, and the answer I received today was, this specific oil contains 0,10 % zinc which, according to Shell, should be enough to keep our engines going without worrying for there´s condition.

Any comments?
