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

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
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.
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.
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
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

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.
