2 things,
1: this is the very first time I have heard of ZDDP being a engine
killer, I have never heard anything bad about it. I have heard its
useless and its useful but never bad. Care to elaborate on why you
think this ?
2: That castrol is syntec, they no longer make a old car guy oil, just
the syntec stuff. My older cars already leak enough oil, I would hate
to see how much oil would pour out if I put in synthetic, my new cars
run synthetic though.
