If you're operating under *severe* conditions, e.g., racing, then
it might be worth it. All that I have heard from people who have torn
down motors beyond 80K is that if you change the oil and filter every 3K,
then the crosshatch from the original factory cylinder honing will still
be visible in the cylinder bores. Sounds like dead dinosaurs do the job
just fine.

It is included at the end of this article.

From what I understand, Castrol uses the best additive package
of all dead dinosaur oils, so that's what I use. Kendall is commonly
used by dealership service departments, which I don't trust to do anything
except maximize their profit, so I don't respect their choice of oil.
That,
of course, is nothing but my own personal bias and should be taken or
discarded as such.
