Dave,
 
    Several people have recommended Delo 400 to me.  I looked up the specs and they are 0.13% zink.  Is that about 1300 ppm?
 
    Costo is selling the Delo 400 for $31 for 3 gallons right now.

For a non-roller cam
..You want>900 ppm
..Optimum is about 1200 ppm which gives you some room for depletion
(which happens during normal running)
..Folklore says>1800 ppm gets you into some embrittlement issues.

Going silent now.
