Yup, if you have 1800 ppm of ZDDP you should be good to go. Likely this is the case with Penrite, although your advertising that you quoted is very vague about what it actually really states.
ZDDP is zinc and phosphorus in a specifically combined compound (
http://en.wikipedia.org/wiki/Zinc_dithiophosphate)
but your stated advertised number that you have been given is for zinc alone.
If you have a decent ZDDP compound in there you should have some relatively large (nearly equal) phosphorus percentage that is in proportion to that zinc. If your stuff were right it would be 1800 ppm zinc and roughly 1600-1700 ppm of phosphorus. (Why different? Zinc weighs more than phosphorus and everything is calculated off of weight)
People who sell oil with zinc powder mashed up in it wouldn't be selling a proper ZDDP compound, now would they?
If you read the Wikipedia reference above it sort of tells you how to make the stuff up which has to be done before putting it in the oil.
Normally folks will give you an analytically based number for ZDDP which has a slightly larger zinc number and a nearly matching phosophorus number.
Where is Zena's razor edged chakra when I need it ??? --- your advertising person needs a bit of a neck trim for either not knowing what he is actually trying to say, or else he's being all vague to you again on purpose. There are some oil makers out there in the past that added the zinc and the phosphorus numbers together then stated it combined (which gives you about half of real ZDDP compared to what you actually need). Not saying this is the case this time, but who knows unless you ask? Stating the ZDDP just off the zinc number of the compound was commonly done in the past, which is likely what Penrite is doing here, just being a little bit lazy in their communications.
The best numbers for the guy to have given you is the analytical PPM of zinc and the analytical PPM of phosphorus and a statement it is in a ZDDP compound.
You see, BITOG's Blackstone Labs (and every other lab) tracks this stuff by spectographic analysis which breaks all compounds down into separate atoms and then simply says you had this much zinc and this much phosphorus .... so getting numbers that you know what they are intended to represent is important.
I remember one instance of one junk off brand oil that showed up in the early American Petroleum Institute testing that the folks put zinc powder and phosphorus powder directly into their Quik Pik special oil (made from 100% specially filtered "recycled" oil no less) -- just very fine flakes of powder that settled out in storeage ..... BITOG reported their oil to be close to the ppms of worn out used oil of each compound, plus it was still containing all the iron and copper wear products commonly seen in well used oil.
To which the idiots responded "We put it in there, did you shake it up good?" The theory being that zinc and phosphorus would combine into ZDDP naturally, something that was actually thought at one point in time by some folks. It doesn't work that way, surprise.
BUT, when you carefully read the labling using full knowledge the guys didn't really lie, they had just stated things selectively and had sneakily put in raw zinc and phosphorus that they thought the labs would find as a raw number
after they had atomized the used oil in a spectrometer.
=================
Penrite isn't stupid nor are they low rent, they are just likely giving you an answer to the question they thought you had asked.
As far as the noddy dude seeking tourists to come shoot his "multiplying like jackrabbits" farmed deer actually being a bad representation of reality, yeah I caught that.
He's just advertising his own brand of oil in his own special way.Right now he likely makes as much money off his Youtube channel hit dollars than he does off his trout guiding business ....
The same 2 rifles do all the shooting and the paths everyone walks down are the same. And I also get that some of the verbage and deer populations and ear bounty stuff has likely changed since he started up doing these videos (he's certainly gotten older looking in his videos).
However, I also caught that the place is BEAUTIFUL and verdant year in and year out with lots of sorts of green growing things that I have never seen before. And he has LOTS of deer to shoot, herds of each kind it seems. BTW, the red deer stags are amazing ....
And yes, I have daydreamed about going to New Zealand on a vacation, but will never be able to do so because of my wonderful government turning me into a pauper in my old age. Plus I could never make it up those hills any more, my legs are too shot.
But I can still dream.
And I can go to the NC/Tennesee mountains at least once a year. I can ride them curvy roads that other people just dream about.
