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.
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.
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 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. 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.
