[6pack] ZDDP and modern engine oils

[Foster, Stan]

Bob Lang mentioned this issue to me the other day and it went in one ear and
out of the other. The message finally sank in when I talked to a local
machinist who was telling me about the high numbers of flat tappet engines
that are starting to fail due to worn out cams and tappets.

Am I the only one on this list that doesn't know and is still using off the
shelf 20/50 with no additives ?

There is a good review of the situation here:

The guy at the machine shop was suggesting a Crane additive or Comp Break In
Additive (include a bottle with each oil change) and Bob L mentioned special
oils designed for Diesel engine or racing engines etc. All of the remedies
mean doing something more than what I'm doing today..
