Car Craft mentions Shell Rotella-T in an answer to a question in
their "What's Your Problem" tech section, Sept. '06 issue.
The question is titled "Valve Clatter", in relation to valve train
noise. I n the answer, Car Crafts Jeff Smith mentions the lack of
zinc and phosphorous in current oils, pointing out that a bottle o
anti-wear additive is essential for cam break-in. Further, he says:
"But the problem doesn't stop there. Many cam companies now suggest
using engine oils with higher levels of zinc and phosphorous for
engines equipped with flat-tappet lifters. Shell Rotella T is diesel-
engine oil that offers these increased antiwear additives and is safe
to use in gasoline engines. Another alternatives is using one of the
high-performance oils from Quaker State, such as the Q racing oils ,
which contain higher levels of antiwear additives and can be used
safely in street engines. The oils cost a little more, but they may
prevent a flat-lobe problem down the road."
I just thought that it was interesting, in light of our discussions
of oil, zinc, and phosphorous some time ago.
On digest mode, so I'm a little slow...
