Paul, Rotella T with Triple Protection 15W-40 CJ-4 has approximately 1200 ppm 

zinc anti-wear. This is 50% more zinc than current passenger car motor oils (API 
SM/ILSAC GF-4) which contain approximately 800 ppm zinc. Passenger car motor 
oils had approximately 1200 ppm zinc prior to 2001. In 2001 the zinc was reduced 
to 1000 ppm and in 2005 reduced again to the current 800 ppm. 
 
Thus, the new Rotella T with Triple Protection 15W-40 CJ-4 has the same zinc 
content that passenger car motor oils had in 2000 before the current problems 
with flat tappet engines began. 

Thank you for your interest in Shell products.

there is a raging debate with serious words being fired across the wires with my 
car club membership.
A fair number of our cars are from 1955 to 1965 and a strong percentage of them 
were originally built with solid lifter camshafts, 80% plus.
Modern Oils are being blamed for the death of flat tappet cams right and left. A 
suggested cause has been the reduction in zink additives in new motor oils as 
mandated by the USA EPA. ZDDP has been bandied about as a term associated with 
this. Some members have taken to using Shell Rotella T oil to gain back the 
protection properties needed.
Does Shell Rotella T contain enough ZDDP to protect as the oils of the 50's and 
60's did in this application?
Thanks
