uh oh, everyone watch the fine print on the Rotella that you buy. Few weeks ago I went to Walmart here in Los Angeles to stock up on Rotella. I bought a few years worth. Well when I read this post last night I went out to the garage to check and the stuff I got is CJ-4 which Vikki says is not really what we want. I've seen Rotella in a bunch of other stores but haven't checked their version.

So I headed back to Walmart and now have a few years worth of STP oil treatment to go along with my Rotella CJ-4. STP stuff says ZDDP included on the bottle though I didn't see a percentage.
