AMSOIL Ea Oil Filters
Continuing on the path to revolutionize the filtration
market, AMSOIL is introducing the new Ea Oil Filter line. Ea Oil Filters feature
advanced full synthetic nanofiber technology, making them the highest efficiency
filters that are available for the auto/light truck market.
Advanced Media Technology
Cellulose and blended medias found in most oil filters have larger fibers than
the synthetic nanofibers found in the EaO Filters. They also have larger spaces
between their fibers. This causes contaminants to load in the depth of the media
and plug the oil-flow path, resulting in higher restriction and less capacity.
The smaller fibers in synthetic media also have a controlled
size and shape. This results in greater efficiency and capacity than cellulose
filters, as well as better durability. AMSOIL Ea Oil Filters provide a higher
level of engine protection, as well as extended filter change intervals.
Oil Filtration Basics
Clean oil is vital to engine performance and durability. Oil must lubricate,
cool and clean the engine as it circulates. In order to remain effective it must
be filtered as it cycles.
The filter is connected to the engine sump, which contains the
oil pump. Full-flow filters pass all the oil output from the pump through the
The function of the oil filter is to remove the contaminants
introduced into the lubricating oil and prevent them from reaching sensitive
engine parts without restricting normal oil flow to the various points requiring
lubrication. Internal sources of contamination include wear products from the
rubbing surfaces of the engine, blow-by gases leaking past the rings of the
pistons and degradation of the oil itself. A filter must perform well in the
areas of efficiency, capacity, flow and life.
Efficiency is the filter’s ability to capture contaminants. The more efficient
a filter is, the more contaminants it will remove from the oil. To make a filter
more efficient the spaces between the fibers in the media are made smaller,
creating more resistance and limiting the oil’s ability to flow through the
filter. Achieving maximum efficiency along with limited resistance is critical
to good filtration.
Extensive testing shows that AMSOIL Ea Oil Filters achieve a
near-perfect absolute efficiency rating. The exclusive new technology used in
AMSOIL EaO Filters provides filtering efficiency to 98.7 percent at 15 microns.
EaO Filters are the most efficient filters that are available for auto/light
Capacity is the amount of contaminants a filter can hold and still remain
effective. When a filter reaches maximum capacity the oil continues to flow
through unfiltered, leaving harmful contaminants circulating in the oil. When a
filter reaches maximum capacity it also reaches the end of its life and must be
AMSOIL EaO Filters have a far greater capacity than competing
filter lines. When used in conjunction with AMSOIL synthetic motor oils in
normal service, EaO Filters are guaranteed to remain effective for 25,000 miles
or one year, whichever comes first.
AMSOIL Ea Oil Filters are made with premium-grade full synthetic media. The
strictly controlled processing of this media ensures accurate fiber construction
and allows Ea Oil Filters to deliver higher capacity and efficiency, along with
Over the service life of a cellulose filter, hot oil will
degrade the resins that bind the media. EaO Filters’ full synthetic media
technology uses a wire screen backing that is pleated with the media for
Ea Oil Filters are constructed with HNBR nitrile gaskets that
are fully tested to extreme distances in numerous severe environments. The
filters also feature fully tucked seams, a molded element seal, roll-formed
threads and a long-lasting premium-grade silicone anti-drain valve.
Proper oil flow is essential to keep moving parts lubricated at all times. A
filter without adequate flow properties can cause catastrophic engine failure.
Flow is restricted as the spacing in the filter media is made
smaller to provide greater efficiency. The synthetic nanofibers in AMSOIL Ea Oil
Filters allow maximum efficiency without restricting flow. This provides
unsurpassed cold-start performance and ensures proper levels of lubrication
throughout the engine.
Extended Service Intervals
AMSOIL EaO Filters are guaranteed for 25,000 miles or one year, whichever comes
first, when used in conjunction with AMSOIL Synthetic Motor Oil in gasoline and
diesel vehicles in normal service. They are guaranteed for 15,000 miles for
severe service. This coincides with the AMSOIL 25,000-mile/one year motor oil
drain interval, adding even more convenience for motorists by consolidating
EaO Filters are recommended for use up to two times longer
than OEM recommendations for commercial units, fleets and RVs using diesel
fueled engines, not to exceed 60,000 miles for heavy-duty on-highway diesel
EaO Filter Q & A
Why is the AMSOIL EaO synthetic media better than cellulose
based oil filtration media?
Synthetic media have submicron diameters (nanofibers) and
small inter-fiber spaces which result in more contaminants being captured on the
surface of the media and lower restriction. Cellulose fibers are larger and have
larger spaces between the fibers, causing the contaminants to load inside the
media and plug the flow path, resulting in higher restriction and lower
Why does the AMSOIL EaO Filter use wire mesh?
The synthetic media needs support.
Will the AMSOIL EaO Filters remove soot?
AMSOIL EaO Filters were designed to meet the filtration needs
post EGR engine development. However, these are full-flow filters and are not
designed as a soot control device.
How long do Ea Oil Filters last?
EaO Filters are guaranteed for 25,000 miles or one year,
whichever comes first, when used in conjunction with AMSOIL Synthetic Motor Oil.
AMSOIL recommends changing the oil filter at the time of oil change.
Why were the SDF Filters phased out?
AMSOIL is continually searching for new and innovative
technologies to enhance its product line. With the advent of the nanofiber
filtration media, AMSOIL desired to be on the cutting edge and provide the most
innovative oil filter technology in the auto/light truck market.
What is AMSOIL’s filter warranty?
AMSOIL warrants that its filtration products are fit for use
according to AMSOIL’s recommendations and warrants its products to be free of
defective materials, design and workmanship.
What kind of vehicles are the AMSOIL EaO Filters designed
AMSOIL EaO Filters are designed for cars and light trucks
equipped with gasoline engines and some diesel pickups.

Engineered for Outstanding Oil Filtration Efficiency
The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration
protection against wear and oil degradation. Working in conjunction with the
engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by
filtering oil on a “partial-flow” basis. It draws approximately 10 percent
of the oil pump’s capacity at any one time and traps the extremely small,
wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea
Bypass Filter typically filters all the oil in the system several times an hour,
so the engine continuously receives analytically clean oil.
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal
operating RPMs the EaBP Filter will filter all of the oil in a typical five
quart sump in less than 10 minutes.
The superior construction of AMSOIL EaBP Filters provides better sealing and
increased longevity along with superior corrosion resistance. AMSOIL EaBP
Filters have a marine powder coated exterior; and their zinc-dichromate base
plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an
orange silicone anti-drain valve. The two stage pleated and layered
cellulose/full synthetic media has an efficiency rating of 98.7 percent at two
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson
Endurance™ filter, the EaBP should be changed every other full-flow filter
change up to 60,000 miles. When used with other brands of motor oil or full-flow
filters, the EaBP Filter should be changed every other full-flow filter change.
AMSOIL recommends using oil analysis when extending oil drain intervals.
Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil
cooling and ensures that equipment constantly runs on clean oil. Engine
efficiency is increased, providing extended engine life.
AMSOIL has designed a new high-efficiency by-pass filter element that is also a
soot removal device. AMSOIL Ea By-Pass Filters use a synthetic/cellulose
sandwiched media. The inner layer of the element is composed of a highly
efficient cellulose media covered with a full synthetic media outer layer. These
filters remove 39 percent of soot contaminants less than one micron. Soot
removal efficiency increases approximately 10 to 14 percent when the EaBP Filter
is used in conjunction with a standard full-flow filter.

AMSOIL Ea Air Filters
The Absolute Best Air Filtration Available for Cars and Light Trucks.
Guaranteed for 4 Years or 100,000 miles
AMSOIL Ea Air Filters represent a major breakthrough in
filtration technology. The revolutionary nanofiber technology used in AMSOIL Ea
Filters captures more dirt, holds more dirt and allows better air flow than
conventional air filters. AMSOIL Ea Filters improve engine performance and help
engines last longer.
AMSOIL Ea Air Filters are the most efficient filters available to the car/light
truck market. Ea Air Filters’ synthetic nanofiber media removes five times
more dust than traditional cellulose filter media alone and 50 times more dust
than wet gauze filter media. AMSOIL Ea Air Filters have a service life of
100,000 miles or four years, whichever comes first.
Better Air Flow
AMSOIL Ea Air Filters allow more airflow than filters that use cellulose media
alone. Cellulose fibers are larger than nanofibers, and have larger spaces
between the fibers, causing contaminants to load in the depth of the media and
plug the airflow path, which results in higher restriction and less capacity.
The synthetic nanofibers in EaA Filter media have submicron diameters and small
interfiber spaces, which result in more contaminants being captured on the
surface of the media and lower restriction.
AMSOIL Ea Air Filters hold up to two and a half times more contaminants than
cellulose air filters. Since the nanofibers in the media are so small there are
more pores per square inch, allowing for higher dirt-holding capacity and lower
pressure drop when compared to cellulose filter media alone. Thinner media
fibers produce more uniform pore size distribution, improving the filter’s
overall quality and ability to capture and retain particles. Testing shows that
Ea Air Filters hold 15 times more contaminants than a wet gauze type filter.
Cleanable - Longer Life
When cleaned according to AMSOIL specifications and used in normal service,
AMSOIL Ea Air Filters are guaranteed for 100,000 miles or four years, whichever
comes first. EaA Filters remain effective for 25,000 miles or one year before
requiring cleaning. This coincides with the AMSOIL 25,000-mile/one-year motor
oil drain interval, adding even more convenience for motorists by consolidating
routine maintenance. (See below for cleaning instructions.)
Above: AMSOIL Ea Air Filters hold 15 times more dust than a
wet gauze type filter.
Above: AMSOIL Ea Air Filter media removes 5 times more dust
than traditional cellulose filters and 50 times more dust than wet gauze.
AMSOIL Ea Air Filters provide superior air filtration for vehicles in the
auto/light truck market.
EaA filters should be cleaned every year or 25,000 miles, whichever comes first.
Carefully remove the filter from the housing. Clean the housing with a shop
towel, being careful not to knock contaminants into the air inlet. Filters can
be cleaned by carefully vacuuming the filter media on the dirty side, or by
holding the filter with one hand and carefully blowing the filter media at a 45
degree angle on the clean side using low-pressure shop air (15-20 lbs. psi).
AMSOIL Ea Air Filters are guaranteed for four years or 100,000 miles, whichever
comes first. The guarantee applies only if the filter has been serviced
according to AMSOIL recommendations. In off-road, frequently dusty or other
severe duty applications, clean and change more often as determined by operating
conditions or as indicated by restriction gauge.
AMSOIL warrants that its filtration products are fit for use according to
AMSOIL’s recommendations and warrants its products to be free of defective
materials, design and workmanship.
