I've always thought ticking on startup was simply caused, as long as the lifters were good, by a fluid film not being established and metal-on-metal contact occuring between the lifter and pushrod.
If true, would any particular additive help prevent this contact before a fluid film is established?
(Yes, I realize a lighter weight oil would probably help, but I'm just concerned with additives at the moment)
The only thing I can think of is molybdenum
Suggestions?
