 
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 filter.
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.
Absolute Efficiency
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 trucks.
Maximum Capacity
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 changed.
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.
Durable Construction
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 better durability.
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 superior strength.
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.
Imroved Flow
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 routine maintenance.
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 applications.
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
capacity.
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 meed 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.
Can I still purchase AMSOIL SDF Filters?
AMSOIL SDF Filters will be available while supplies
last. They are no longer available for online purchase.
Why are the SDF Filters being 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.
Will SDF Filter warranties still be honored?
Yes, if an SDF Filter is deemed defective in
accordance with the AMSOIL filter warranty, AMSOIL will replace
the defective SDF filter with a comparable EaO filter or will
credit the customer's or Dealer's account for the purchase price
of the SDF filter.
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 for?
AMSOIL EaO Filters are designed for cars and
light trucks equipped with gasoline engines and some diesel pickups.
How many EaO Filters are being offered?
AMSOIL will carry 35 EaO Filters for the most
popular auto/light truck applications. AMSOIL will continually
study providing filters for additional applications.
If AMSOIL does not offer an EaO filter for
my vehicle, what do I do?
AMSOIL will continue to offer other oil filtration
products for auto and light truck applications. AMSOIL will provide
name brand filters for most applications that are not covered
by AMSOIL labeled products.
How do I cross reference my current filter
or application?
The most up-to-date source for filter application
information is the electronic
auto/light truck cross reference guide on the AMSOIL website.
All Ea oil and air filters are included.
What about the auto/light truck filters you
do not cross to?
AMSOIL currently has a supplemental line of filters
for auto/light truck applications and will be announcing a new
partner to enhance this availability in December.
