Layman's Guide to Synthetic Oil
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.
