zddp in my other cars?

[Ryan]

Guess I'm sold on using zddp in my GN. Should I stick it in my 02 and 06 Ford Focus. I know......I used the F word. Don't think I would need it since they are overhead cams but figured I'd ask.

also, can you use it in synthetic oil?

My opinon

is to use it in older flat tappet cam engines, It is an additive so it wont hurt in newer cars(roller cams) and synthetic oil. Lets see how many different opinons you get on this.
