Absolute Efficiency Oil Filters by AMSOIL
The only complete line of automotive and light truck oil filters still Made in USA!
AMSOIL EA OIL FILTER:
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.

Advanced Media Technology
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.
Thanks to Donaldson Filtration - We have a unique partnership to bring our customers the only Nanofiber Oil filter available to Lt. Trucks, Passenger Cars and Motorcycles. Donaldson provides the filter media to AMSOIL to our specifications. This technology is based on Donaldson's Endurance Series and is reviewed yearly for the latest improvements.
Should we not have a filter for your car or truck, we also stock the next to the best product by WIX and MANN too add to your ordering convenience with AMSOIL Products.
Oil Filtration Basics
What is 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 containing conventional cellulose media range from 40 to 80 percent efficiency at the benchmark 20 micron.
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.
Hint: - My advice on choosing the best oil filter is to buy the one which isn't afraid to show you both sides of the Equation! Many tell you we are 98% efficient (or 100%) per the ISO-4548 Test - but what they fail to tell you is what the smallest micron was captured at that 98%.
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, premium-grade silicone anti-drain valve.
Due to Donaldson's manufacturing practices within our EAO and EA15K line, you will never find a better built oil filter elsewhere. Eliminating the resins alone should convince you of the built in insurance for flow in all conditions. There are a lot of big name filters which do say we have breakthrough technology but they never offer both sides of the equation, do they?
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.
Consult the AMSOIL Online Application Guide or MyAMSOILGarage™ at the main site 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.

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 meet the filtration needs post EGR engine development. However, these are full-flow filters and are not designed as a soot control device. If you need to remove soot a more restrictive filter such as our By-pass or partial flow 2-micron units will be needed.
What does Ea Mean?
AMSOIL Ea Filters are evaluated with the beta ratio test in order to validate
In the test, fluid containing particles of a known size is filtered through
Why doesn't other filter companies give us more information like this?
Well if they did, then they would have to make a better filter. The costs of doing so would eat into profits which would upset the stock holders. Best to not upset the apple cart. AMSOIL has always had the policy to make the best and to continue the lead no matter the costs. There are no stockholders to issue a compromise.
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 EaO Filters are being offered?
We have 40 EaO and EA15K 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?
Don't forget to review the new AMSOIL Absolute Efficiency Air Filters. If you are in the mood to save money, see how much time and money you save with these. They are incomparable! If you are not using a stock filter, see the Cold Air induction type.
The prior and discontinued SDF series of AMSOIL oil filters were very similar to the micro blend design currently marketed by many other "Premium filter" brands which are made in Mexico. Currently one major label remarks that they have a 99.2% efficiency rating per ASTM testing but they fail to note at which micron size filtration. That answer is about 30 microns.
AMSOIL offers the consumer guaranteed "Absolute Efficiency" protection and offers you the whole equation - 98.7% efficient throughout our recommended intervals.
