How
Important is your
Oil Filter?
Compared to
microscopic dirt
particles, your
engine is a
Goliath...
Roaring with
heat and energy as
it converts raw fuel
into horsepower. But
despite all this
power, your engine
is extremely
vulnerable to the
threat of
microscopic engine
dirt. In fact, if
unchecked, this tiny
menace will
dramatically erode
your engine's
performance and can
eventually cripple
it beyond repair.
THE PROBLEMS
Engine Wear
- Automotive
experts agree that
dirt is the number
one cause of engine
wear. At first
glance, it does not
seem possible.
Engine dirt
particles are so
small -mere dust
specs- and an engine
is a highly
sophisticated piece
of machinery,
crafted from the
most durable metal
alloys. How can
these minute
particles bring down
such a high-tech
giant? The answer
lies in the fact
that dirt particles
are extremely
abrasive. They
consist of
razor-like flakes of
road dust and
airborne grit drawn
into the engine
through the air
intake, as well as
manufacturing scarf
and wear metal
particles generated
inside the engine.
These particles are
carried by the oil
into the precision
clearances between
bearings and other
moving parts. Once
they work in between
these parts, they
grind and gouge
surfaces, altering
clearances, and
generating more
abrasive debris. As
this wear cycle
continues, precision
components become
progressively sloppy
and fatigued until
they fail
altogether.
Oil Degradation
- In
addition to
physically
assaulting engine
components, dirt and
other contaminants
work to degrade the
oil that provides
vital engine
lubrication. Sooty
particles generated
during combustion
can be forced past
piston rings and
into the oil. These
particles act like
tiny sponges,
absorbing critical
additives and
shortening oil life.
Soot also wreaks
havoc with viscosity
by causing oil to
thicken. And in the
presence of
moisture, common
by-products of
combustion will
react chemically to
produce corrosive
and rust-producing
acids.
THE SOLUTION
AMSOIL
Oil and
Air Filters -
Filtration is the
key to preventing
costly repairs
caused by engine
dirt. Filtration is
simply a method of
Removing
contaminants by
trapping and holding
them outside the
system of oil
circulation. In
order for filtration
to be truly
effective, however,
it must be able to
capture contaminants
of all types and
sizes.
AMSOIL
has
developed a complete
line of
sophisticated
filtration products
designed to offer
the best protection
available against
virtually all
harmful engine
contaminants. With
an
AMSOIL
2 Stage
Air Filter, an
AMSOIL Duty Oil
Filter and an
AMSOIL
By-Pass
Oil Filter, your
engine can run long
and hard with
outstanding
protection against
engine dirt.
AMSOIL
SDF OIL
FILTERS Full-flow
filters install
directly into the
line of oil
circulation. The
full flow of oil
passes through the
filter as the oil
journeys between the
oil pump and engine.
A full flow filter
must be capable of
removing and holding
contaminants without
obstructing oil flow
to the engine.
Most conventional
filters on the
market use a thin
layer of porous
filter paper as
their filtration
media, which
compromises their
ability to catch
fine particles. In
addition, these
filters have almost
no extended cleaning
ability since their
media have a low
capacity for storing
dirt.
Because of their
limited filtering
area, most
conventional paper
filters display good
flow characteristics
but are restricted
in their capacity
and longevity. They
become obstructed
relatively quickly,
opening the relief
valve and allowing
unfiltered oil into
the engine. Their
lightweight
construction also
makes them
susceptible to
degradation.
AMSOIL
SDF
FILTERS WORK BETTER
- LONGER!
AMSSOIL
Super
Duty Filters (SDF)
feature an advanced
fiber media offering
the ready flow of
oil hard-working
engines demand with
superior capacity,
efficiency and
service life to that
offered by
conventional paper
oil filters. In
fact, the SDF has
over a 75% better
combined
efficiency/capacity
rating than other
popular oil filters
as tested according
to the Society of
Automotive Engineers
industrial
standards.
The
AMSOIL
SDF may
be used for
intervals of 12,500
miles or six months
(whichever comes
first) in gasoline
engine applications.

WHY ANOTHER
FILTER? Even the
best full
flow-filter can't do
it all.
Any full
flow filter must
allow oil to pass
through it quickly
to keep the engine
from starving for
oil. Advances in
auto technology and
more compact engine
designs place
increasing demands
on these filters; to
keep from creating a
circulation
bottleneck they
filter out only the
coarser particles,
and feature relief
valves that open
when the engines
demand for
lubrication can't be
ignored.
But the smallest
grit that passes
through road dust,
manufacturing scarf,
and engine
metal-flake in the
5-20 micron range
accounts for up to
60% of all engine
wear. These
microscopic
particles closely
match the precision
clearances between
critical engine
components; they can
enter the spaces
between bearings,
rings, and other
components, to
damage metal
surfaces, altering
tolerances,
fatiguing components
and generating
additional debris.
Automobile
engines are also
susceptible to
damage related to
water formation,
something a full
flow filter is
powerless against.
Water enters the oil
either as blowby
combustion product
of fuel ignition, or
as condensed
moisture from air
drawn into the
engine through the
air intake. Water
causes metal
surfaces to rust; it
also reacts with
other blowby
contaminants to
produce corrosive
acids that attack
the engine,
contributing to
further friction,
wear, debris, and
oil degradation. The
AMSOIL
Solution-By-Pass
Filtration Unlike a
full-flow filter,
the
AMSOIL
By-Pass
Filter is situated
outside of the main
line of oil
circulation; it taps
into the line to
bleed off and clean
only a portion of
the oil at a time.
The
AMSOIL
By-Pass
Filter retains the
oil longer and does
a more thorough job
of removing
contaminants without
obstructing flow.
You still need a
full-flow filter, of
course, because oil
must circulate
continuously. But
with an
AMSOIL
By-Pass
Filter drawing 10%
of your system's
capacity, all the
oil in a six-quart
system will be
filtered to
analytical purity in
about five minutes,
at an average engine
speed equivalent to
45 mph.
The
differences between
the
AMSOIL
By-Pass Filters
and
others are the
unique design of the
filtering media and
the patented
construction of the
filter element. Our
high-capacity
filtration medium is
a special blend of
virgin wood and
cotton fibers formed
into disc, stacked,
and compressed. The
center tube is
all-steel,
perforated for oil
flow and wrapped
with a fine mesh
cotton screen. All
dirt particles down
to one-tenth of a
micron in size are
trapped, and the
medium's thirsty
cellulose fibers can
remove up to a pint
of water. Channeling
is eliminated with
the inclusion of a
hydraulic follower
plate activated by a
sophisticated
internal pressure
system.
The
AMSOIL
Dual-Remote Oil
Filtration System
For Optimum
OIL FILTRATION and
Maximum SERVICE
ACCESSIBILITY.
The
AMSOIL
Dual Remote
Oil Filtration
System replaces the
standard full-flow
system
with a
combination
full-flow/by-pass
system using a
remote mounting
assembly. The mount
couples an
AMSOIL
Full
Flow Oil Filter with
an
AMSOIL
Spin-On
By-Pass Filter; it
takes oil from the
engine and returns
it without the use
of multiple fittings
or extra return
holes in the oil pan
or valve cover. The
mount and filters
are installed in an
accessible area of
the engine
compartment.
A
specially-manufactured,
spin-on casting with
threading adapters
is simply screwed
onto the engine
block's filter
nipple, replacing
the old full-flow
filter. In-and-out
ports in the casting
and two flexible oil
lines connect this
adapter to the
remote mount.
Remote placement of
the filtration unit
allows larger oil
filters to be used,
and increases sump
capacity -
dramatically
extending the oil's
useful service life
and protecting your
wise investment in
AMSOIL
Synthetic Motor Oil.
The recommended
replacement interval
for the
AMSOIL
By-Pass
Oil Filter is 25,000
miles or one year
(whichever comes
first) or longer if
using oil analysis.
The Super Duty Full
Flow filter is
changed at 12,500
mile or 6 month
intervals (whichever
comes first) for
gasoline engines.
Once the
Dual-Remote
Filtration System
is
installed, and you
elect to use oil
analysis testing,
then you DO NOT need
to change your
engine oil unless
oil analysis testing
results indicates
you need to. Test
samples are easily
pulled from the
dipstick tube with
an
AMSOIL
pump
into a 3 oz bottle
and then put into a
postage paid box
mailed to Oil
Analyzers Inc. This
is typically
performed every
20,000 miles or
every year,
whichever comes
first for passenger
vehicles and light
duty trucks. You may
very well travel
several hundred
thousands of miles
without needing to
change your oil when
using oil analysis
testing. It really
is a simple process
and provides an
accurate analysis of
your engine's
internal condition.
Oil analysis testing
is common practice
with commercial,
fleets and
heavy-diesel
equipment that you
can put to use for
your benefit as
well.
