Absolute Efficiency
AMSOIL Ea® Oil Filters (EaO, Ea15K) have one of the best efficiency ratings in the
automotive/light-truck market. Ea Oil Filters provide a filtering efficiency in accordance with
industry standard ISO 4548-12 of 98.7 percent at 20 microns, while competitive filters demonstrate
efficiencies as low as 51 percent.
Less Restriction
AMSOIL Ea Oil Filters have lower restriction than conventional cellulose media filters. Their small
synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction.
During cold-temperature warm-up periods, an Ea Oil Filter allows the oil to flow through the filter
more easily than a typical cellulose filter does. Lower restriction decreases engine wear.
Contaminant Retention
A filter’s capacity refers to the amount of contaminants it can hold and still remain effective.
AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing
filter lines. In fact, when used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil
Filters are guaranteed for up to 15,000 miles/one year, whichever comes first, or 25,000 miles/one
year, whichever comes first, depending on application and severity of service.
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. 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 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, premiumgrade silicone anti-drain valve. They
also feature fluted cans for improved grip.
Applications And Recommendations
AMSOIL Ea Oil Filters provide superior oil filtration for cars and light trucks.
Service Life
When used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for
extended service life:
• Ea Filters designated with product code Ea15K are recommended for 15,000
miles/one year, whichever comes first, in normal or severe service.
• Ea Filters designated with product code EaO are recommended for 25,000
miles/one year, whichever comes first, in normal service or 15,000 miles/one year, whichever
comes first, in severe service.
Consult the AMSOIL Online Application Guide or MyAMSOILGarage™ at www.amsoil.com to determine the appropriate filter for each
application. When AMSOIL Ea Oil Filters are used with a motor oil other than an AMSOIL extended
drain motor oil the filter should be changed according to the vehicle manufacturer
recommendation.
