Royal Purple Synthetic Oil

Yea. it was late when I wrote the email so Amsoil is correct. Ya liked
the way I spelled Valvoline too ?? ha.

I agree with you, I was surprised that they admitted to the fact it
couldn't carry the break in load of a lightly loaded gear. I fact Crane
Cam, MSD, Mallory and other suppliers require one to 'NOT' use
synthentic oil during any break in of their parts either.....

Yes, but typically the reason that synthetics aren't recommended during
engine break-in is because they protect the parts too much, not because
they protect too little. The parts need to wear in against each other
and often synthetics prevent this "normal" wearing in process and thus
cause problems later, generally with rings that don't seal well.

I'd never use synthetic during initial break-in, but I can't believe it
caused the problem you experienced, although, I'll admit to using only
Mobil 1. I've never been an AMSOIL fan, but that is based admittedly on
the fact that I find their marketing so "over the top" that it causes me
to also mistrust anything else they claim.

A friend works in a refinery and they love synthetic oils in their
units.
They used to get 4 years on turbine bearings and are almost upto seven
years and still running well. They are hoping to get upto eight years
like some of the other area refineries. They swear by synthitic oils.
Another thing they do to increase the life of bearing is to prefilter
the oils before adding them to gear boxes.

All turbine oils are synthetics. They are not suitable however to put
in a recip.

There are differences in the synthetics which are used for turbine,
gearbox, recip. engines (2-stroke or 4-stroke) and other mechanical
devices.
There are differnces in conventional lubricants as well.
The proper weight of lubricants should be used in the proper
application.
One advantage of a synthetic is water does not readily mix with it as
it does with conventional oils and is also more heat tollorant.
Are you aware there is no cleanliness standard for oil?
Ever look at the bottom of an empty oil bottle? Sometimes there is
sediment.
This is why many industrial plants are using filter carts as part of
their preventive maintenance (PM) program.

Good point Don.
