Advanced Media Technology
Cellulose and blended medias found in most oil filters have larger
fibers than the synthetic nanofibers found in the AMSOIL 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. AMSOIL 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, AMSOIL 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 AMSOIL 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. AMSOIL EaO Filters’ full
synthetic media technology uses a wire screen backing that is pleated
with the media for superior strength.
AMSOIL Ea Oil Filters are constructed with HNBR nitrile
gaskets that are fully tested to extreme distances in numerous severe
environments. AMSOIL 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.
AMSOIL 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.
AMSOIL 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 AMSOIL Ea Oil Filters last?
AMSOIL 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 AMSOIL 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 AMSOIL SDF Filter warranties still be honored?
Yes, if an AMSOIL SDF Filter is deemed defective in
accordance with the AMSOIL filter warranty, AMSOIL will replace the
defective SDF filter with a comparable AMSOIL 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 AMSOIL 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 AMSOIL 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. |
