Amsoil
Ea (Absolute Efficiency) Oil Filters (EAO)
Made
with premium-grade full synthetic media. Ea Oil
Filters feature advanced full synthetic
nanofiber technology, making them the highest
efficiency filters that are available for the
auto/light truck market. 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
in severe service.

Absolute
Efficiency
AMSOIL Ea Oil Filters have the best efficiency
rating in the industry. EaO Filters provide a
filtering efficiency in accordance with
industry standard ISO 4548-12 of 98.7 percent
at 15 microns, while competitive filters
containing conventional cellulose medias range
from 40 to 80 percent efficiency.
Less
Restriction
AMSOIL Ea Oil Filters have significantly lower
restriction than conventional cellulose media
filters. Their small synthetic nanofibers trap
smaller particles and hold more contaminants,
resulting in lower restriction. During cold
temperature warm-up periods, an EaO lube filter
allows the oil to easily flow through the
filter compared to a typical cellulose filter.
Lower restriction decreases engine
wear.
More
Capacity
A filter’s capacity refers to the amount of
contaminants it can hold and still remain
effective. 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.
Superior
Construction
AMSOIL Ea Oil Filters are made with
premium-grade full synthetic media. The
strictly controlled processing of this media
ensures accurate filter construction, and is
what allows Ea Oil Filters to deliver higher
capacity and efficiency along with better
durability.
Over the
service life of a conventional cellulose
filter, hot oil will degrade the resins that
bind the media. The Ea Oil Filters’ full
synthetic media technology is resin-free. It
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.
Applications
AMSOIL Ea Oil Filters provide superior oil
filtration for vehicles in the auto/light truck
market.
Service
Life
AMSOIL Ea Oil 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.
If used in
conjunction with AMSOIL Motor Oil that is being
changed at intervals less than 25,000 miles,
the EaO Filter should be changed at the same
time. AMSOIL EaO Filters are not guaranteed for
25,000 miles when used with any oil other than
AMSOIL Motor Oil and should be changed
according to vehicle OEM
recommendations.
