If you're basing your research on the material data sheets provided by the oil manufacturer's your findings are mostelikely wrong. They do not update the information often enough and many have found through oil analysis that the zinc content is most times lower than advertised. Check out the chevelletech performance forum for a lot of good info on the subject. We may all need to run race oils soon.

Carquest is just Valvoline, nothing special

Saw a message thread, somewhere, where Blackstone? labs was taken to task for incorrect analysis on Valvoline oil for ZDDP. They finally admitted that their equipment was improperly calibrated when the tests were done. The questioning person sent a split sample of VR1 to two different labs in Houston who both reported ZDDP levels slightly higher than the oil company's spec sheet.

I believe this thread was on one of the Chevy /GM forums.

I asume you mean for normal use in the 'non break-in' part. Brad Penn has a break in oil designed for flat tappets, also Cen-Pe-Co and many other 'racing' oils. The idea that once the cam/lifter interface is wear mated you no longer need the additives will lead you to troubles down the road, sooner, or later. If you check the CompCams site their 'flat tappet cam tech bulletin' was revised 3/11/08. This should be common knowledge by now. JMO

L.e.c.

I'm using MotorHead Classic Motor Oil (motorheadoil.com) and it typically has over 1500 ppm zinc (and yes, I've had it lab-tested). It isn't synthetic though..but if you like the synthetics (I don't) they sell their zddp additive separately, and you can use THAT with any oil...it boost a 5 quart oil-change by 700 ppm.

An interesting note on the revised comp cam bulletin linked to in Stroke's post. It appears that the change has been to remove any reference to the Shell Rotella T diesel oil. This was expected as new diesels are required to run cat converters and therefore the new oil must have its ZDDP reduced.

I'm not really looking forward to special ordering my oil for $5 or more per quart...

Hi,
I like you don't like the price,
but at least the money goes to
a US company for Pure Pennsylvania crude,
instead of some Saudi (or whatever you call them)
getting the money, & using it to try & kill us.
