[DeTomaso] How much ZDDP is in this?

[Charles McCall]

Thanks Dave. 

I bought this stuff probably a year ago. Interestingly enough, the current
Mobil 1 page calls this viscosity something else (Peak Life) and not "Rally
Forumula". So I would guess that this is the old formula, perhaps
corresponding to the 1000/1100 number that you quote and that shows up in
the chart that Chuck Engles sent me. 

This is all speculation of course, which makes me a little nervous based on
what I've read about insufficiente levels..

Just so you have more confusion Charlie.
- I have an April 09 listing for that oil as P1000  Zn1100
- If it were north america I believe it would have about 400 points 
taken off it last year which would put it at P600 Zn700
- 1200 is a reasonable minimum target, given that we don't know what the 
additive run-depletion rate is anyway.
- There is a belief that 1800 is a safe limit for P content and that 
there is some kind of embrittlement danger above that.

So all of this is just blowing smoke, but I think I'd add 1000
This is showing faith that there is at least 200 and not more than 800 
in the jug.
If you happen to know that it was blended more than a year ago, I'd get 
a different answer.

It's all pretty shitty though.
