And, isn't all of this crying out for a definitive article from one of our
two magazines, even if the covers get torn and the local mailman reads it
first?
I for one am dizzy reading all of this stuff from the various web sites and
we need something clean and simple.

Subject: Confused - ZDDP and our oils
Help, I'm also confused now regarding Castrol GTX. The website
http://www.lnengineering.com/oil.html lists test results on a number of
engine oils including Castrol GTX 20W50. The test was conducted 11/05 and
The GTX is listed as Type DINO and API SM. Yet the ZDDP seamed good unless
I don't understand them - P(ppm)=1157 & ZN(ppm)=1422. These are at a level
of .1157% & .1422% respectively. Since the tested GTX is listed as API SM,
can I assume that the tested GTX is the most current oil some are saying
does not have sufficient ZDDP levels? Thanks.
Confused.
Vrooom vrooom,
John
