Glenn,
I'm not a mechanic, but mine said ZDDPlus was a mandatory additive since the
zinc is gone out of Castrol. Your report surely proves this!

Also I understand Brad Penn 20w50 is a good alternative as it has the
required
zinc. TRF is selling it.

When I first heard of this, I also found that STP has some zinc, but being a
private formula they won't confirm how much. Better than nothing.
