I'm using Shell Rotella (15/40)  Available almost anywhere.  It has  
1200 PPM ZDDP.

Also, a can of (red) STP added to every oil change has the required  
ZDDP for flat tappet engines (if you want to use Castrol or other  
oils that don't have as much ZDDP in them).

The blue STP has only a slight amount of ZDDP and won't help much.
