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
What is AMSOIL’s filter warranty?

according to AMSOIL’s recommendations and warrants its

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

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.
