Hey Bernd, I didn't know that Amsoil oil filters sold under the Hastings
brand label.

Nice rebuild specs! :)

I do remember (when my dad was still a dealer for Amsoil) that you are NOT
supposed to use synthetic oil until the engine has had a chance to break in
properly (about 7500-15000 miles). Granted, this was quite a few years ago
and
the machining processes are much better now-a-days, but you really don't
have
to run any special oils if you change it on a regular basis (3500 miles).

When my Javelin was torn down for a rebuild (at 185K miles) there was almost
no
wear on any of the lubricated surfaces and she was run on regular dino-oil
with
regular oil changes at every 3500 miles.
