<VV> More on oil and zinc

[iscdirector]

A question for the people with all the technical oil knowledge. I was looking at the selection at Wal-mart and found Pennzoil high mileage to be the only one on the shelf that says on the label "meets or exceeds requirements of SH and SJ" Would this still have the additives in it that makes it ok to use with flat bottom lifters or had the zinc, etc. already been removed for SH like they have been in today's SM?
