Title: ZDDP Booster Blend Table
Post by Boule’tard on 08/15/12 at 18:27:10

As promised, here are the exact amounts of booster needed, in a gallon of Rotella T6 synthetic or to a gallon of Rotella dino Triple Protection, to reach a desired concentration of Zinc in the form of ZDDP. All the way from "adequate" (add nothing and you have 1250ppm) to a relatively HUGE 2500ppm :D

Anyway.. I will attach the spreadsheet to this post (open office format, oops the forum will not let me attach a file with extension ods. Change the extension from zip to ods or xls. It is not really a zip file) so anyone can check my math or expand it out to Mountain Dew "extreme" zinc concentrations beyond 2500ppm.

I have carefully considered the specific gravities of Rotella and each additive when calculating the zinc concentration. Sources for this as well as Zn contents are MSDSs, product web sites, and lab VOAs.

So.. in easy-to-mix 1/8 ounce jigger increments, here it is. Remember, these amounts go in one gallon of Rotella T or T6:

[split] [splithere] (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1395858061)[splithere_end]

The current acceptable limits of ZDDP recommended on this site are between 1,200 and 1,400 and the above table is only applicable to Rotella.

And keep in mind for comparison with the oils below, that earlier oil industry testing has found that above 1,400 ppm, ZDDP INCREASED long term wear, even though break-in wear was reduced. And it was also found that ZDDP above 2,000 ppm, started attacking the grain boundaries in the iron, resulting in camshaft spalling. So, no matter what zinc fans might “believe”, there is such a thing as "too much of a good thing".

One fellow compared it to adding a couple of teaspoons of sugar in your COKE.....not a good thing!

The above statement came from this document....which also has a lot of information for which oils have good reports for low wear. (Remember....these may not be oils suitable for wet clutches - and that a lot of the racing oils do not have the additives for normal oil change intervals...racing oil is often changed after a few runs).

UPDATED JANUARY 2016

Shell has recently stated that the ZDDP level in the Rotella T and Rotella T-6 is 1,200 ppm, and has been since 2008. At 1,200 ppm of ZDDP in the Rotella, most likely the cam and rockers will be lubed adequately without any additional ZDDP. If you want to add some ZDDP - 1 oz. of Redline in each gallon of oil will get you right up to the 1,400 ppm maximum that is recommended.

The folliwing mix table is adjusted to represent the current 1,200 ppm that Shell claims in in their oil.
