Congrats Gerry!

I've done extensive reading on the subject. Zddp has been removed from
automotive oils to keep catalytic converters in top shape. Motorcycle,
diesel, and some "racing" oils still have it.
 
Kragen sells the consumer version, Valvoline 20/50 VR1 "racing" oil. It has
the zddp and the detergent you need. It's rated SM for passenger cars.  

If you want synthetic get RedLine. The others don't have the zddp.
