ZDDP in different oils(SM, SL, SJ...)

[tuckman]

I came across an add for http://www.cam-shield.com (I know its not a BITOG sponsor) and now I have some questions.

1) is this stuff worth the bottle it's put in?

2) What are the max allowable ZDDP levels in SM, SL, SG and in the HDEO's (or a place to find these levels?)

phosphorus- 800 PPM
zinc-850 PPM

You only need it for flat tappet engines.

Where would i find it for all of the S-ratings and C-ratings.

i guess i should have said that seeing this product made me wonder what they all were.

all my engines have flat tappets, so I'm at least a bit curious...

 

[tuckman]

So nobody knows where I can find these numbers?

There has to be a webpage/website that says what the max/min additive levels for the certain classifications of oils!
I am not looking for what oils have what in them but more what is allowable in the certain ratings over the years.

This might help you with recent API specs:

Schaeffers has high levels of ZDDP in their 7000 and 9000 oils even though they are SM rated.

I have a good amount of Muscle cars and 1200 zinc has always been the minimum amount of zinc recommended for an oil. If the engine is already broken in, I would think anything close to that number would be fine. I have used a lot of different oils and in my original survivors with low miles, I use Mobil 1 high mileage 10W40(1000 zinc). It really seems to work well in most of my engines. I do sometimes add a pint of Schaeffers #132 additive to it because I know guys that own expensive cars(Shelby's, etc) and they add it and really like it.

There is a chart at the V-Strom motorcycle site, but I don't know if you can access it without being a member of that forum.

Basically, it shows:
API Designation Year Z% P%
SH 1996 0.130 0.120
SJ 2001 0.110 0.100
SL 2004 " "
SM 2005 0.087 0.080

The percentages = PPM, ie.., 0.130 = 1300 PPM.
