Newer engines I believe are all roller cams, I do not think you can get a new
car with a flat tappet cam. What I have read is two resons, superior qaulity
design aspects of roller cam operation, and roller cams required, because smog
requirements, to reduce emissions many additives being regulated out of oil.
Internet information, not sure how accurate. I have seen several people wipe
out flat tappet cams in short order, especially at break in, and new
installs.

Are we talking mainly about older, rebuilt engines? Many of the modern
ars have no special break in oil or instructions and the engine is under
arranty for 100,000 miles. Are the new engines that much better?

ou have to investigate any oil these days. All oils are reducing
he amount of additives to comply with emissions regulations even for
iesel
ngines. The labels on the bottles tell approximately the level of
dditives but you need to know the label markings. If your breaking in a
ewly rebuilt engine I say always add a bottle of additives to make sure
ou
on't wipe a cam lobe and have to start over.
