I have been a dealer of Ams/Oil since 1974. And let me tell
you that what they say you can take to the bank. I have use
it since '74 in all my cars and never a problem. It is a
good product.

although I
doubt if I will go that long. The system has me changing
one of the
filters every 100 hours and the other at 200 hours and
doing an oil
analysis after every filter change. I will be particularly
intereseted
in acid buildup.

This is supposed to filter out all of the littlest
particles that will
wear our my motor so it will last forever. I will be using
the Amsoil
15-40 Marine Diesel. I'll report back in 20,000 hours.


2 problems with bypass filters- it diverts oil flow that
would otherwise
be going thru the system to the bearings that need it... and
it doesn't
filter all oil delivered thru the system. So, while your
bypass filter
may "remove" little particles, it doesn't prevent other
particles from
getting to the bearings.

Instead of a bypass filter, a better full-flow filter is
desirable IMHO.
The only problem with them is that they're more expensive
and neglect
causes greater engine harm (although if you neglect your
bypass filter,
you probably don't give the regular filter exemplary care
either).
