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 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. |
