Advanced Media Technology
Cellulose and blended medias found in most oil filters have larger fibers
than the synthetic and 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 air-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 and extended filter
change intervals.
Oil Filtration Basics
Clean oil is vital to keep engines running properly. 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. A filter must
perform well in the areas of efficiency, capacity, flow and life.
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.
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.
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 one of the main attributes of a great
filtration product.
Extensive testing shows that AMSOIL Ea Oil Filters
provide data that substantiates 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, and 50 percent at 7 microns. SDF
Filters are not quite as efficient with a filtering efficiency of 94.3
percent at 15 microns and 51.2 percent at 7 microns. EaO Filters are the
most efficient filters that are available for auto/light trucks.
Ea Oil Filter 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 is what
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.
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, 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.
Improved 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.
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 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.
Can I still purchase AMSOIL SDF Filters?
AMSOIL SDF Filters will be available while supplies
last.
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 initially carry 35 EaO Filters for the most popular
auto/light truck applications. AMSOIL will continually study providing
filters for additional applications.
What if AMSOIL does not offer an EaO filter for my
vehicle, what do I do?
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 AMSOIL web site has the electronic
auto/light truck cross reference guide. The guide allows users
to search both by application and by filter part number.
What about the auto/light truck filters you do not cross
to?
AMSOIL currently has a supplemental line of filters from
Wix for
auto/light truck applications.
