So am I reading that right?
It agrees with what TheDemonator was told.
Syn oil doesnt need ZDDP.
Which would be the "safe" thing since the oil companies seem to change the contents of a given oil daily.
:-k
Everything I have ever read said it does not matter whether the oil is synthetic or not. For a flat tappet engine you need the ZDDP. Every cam manufacturer I have seen a statement from agrees.
