Amsoil EA Oil Filters (EaO)

Absolute Efficiency

AMSOIL Ea Oil Filters (EaO) 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 up to 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.



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.


WIX Oil Filters

In the last three years, AMSOIL has introduced more new products and made more technical advances than during any other period in the company’s storied 34-year history. AMSOIL now provides engine oils for nearly every application, multiple gear oils, greases, fuel additives and appearance products. To offer a more wellrounded selection of automotive products, AMSOIL also offers high quality products from other manufacturers such as Twin Air, Donaldson and WIX. Recently, AMSOIL’s focus has been on the filtration market. The recently launched Ea Filter line includes the finest filtration products in the world for the auto/light truck market, and Donaldson covers the heavy-duty market. To complement the Ea line of filters, AMSOIL now offers WIX filters, allowing one-stop shopping for automotive customers. AMSOIL carries over 700 WIX air, oil, fuel, racing and transmission filters for automotive and light truck applications.

A History of Excellence

WIX is well-known around the world for its innovative filtration products for the automotive and light truck market. Founded in 1939, the Gastonia, N.C., company earned acclaim during World War II when it created an oil filter out of a paper tube, wooden plugs and yarn when steel was in short supply. In 1954 WIX created the revolutionary spin-on oil filter that was eventually adopted as original equipment on most vehicles.
Today WIX manufactures some of the best oil, air, lube, cabin air, hydraulic, fuel, crank case breather and transmission filtration products on the market. The company is also widely known for its support of NASCAR.

Superior Construction

WIX oil filters have a full metal base plate for superior strength at the double seal. They also feature a silicone anti-drainback valve that stays flexible in extreme temperatures. This improves oil flow and keeps oil in the filter to prevent dry starts.
WIX oil filters use an up-front by-pass valve. This design is superior to top-mounted valves because it helps to keep oil from washing past dirty media and entering the engine. The glass-enhanced media in WIX oil filters offers greater efficiency, capturing more 10 to 12 micron sized particles than other cellulose/synthetic blend medias. They also have a coil steel spring to ensure internal filter parts are sealed properly.
WIX panel element air filters have a linear path through the filter for low airflow restriction, a specially formulated adhesive to form WIX’s exclusive pocket pleat for the filter media and a soft sealing urethane gasket molded in place on the filter element.
Radial air filters are constructed of mesh screen on the inside wall diameter for element strength and media protection from backfire. Each round filter is manufactured with heat-resistant plastisol with specially designed crush seals on the top and bottom walls and adhesive seal joining the media ends. Additional Filtration Products AMSOIL offers WIX filtration products for auto/light truck and racing applications. This includes not only standard air and oil filters, but fuel, transmission, cabin air and filters specially designed for racing as well.

Fuel Filters

WIX fuel filters provide unmatched fuel cleansing performance. They prevent pump wear, injector clogging, premature engine wear and help boost fuel efficiency. WIX fuel filters offer quick, easy filter replacement, long life and the possibility of extended service intervals. WIX spin-on filters reduce the possibility of improperly installed cover gaskets, and they provide effective, easy draining of excess water on filters equipped with the drain plug. The superior materials, design and construction of WIX fuel filters provide excellent performance under all types of operating conditions.
Transmission Filters
AMSOIL will also offer the full line of industry-leading WIX transmission filters for passenger cars and light trucks. WIX transmission filters provide superior protection for many transmission applications in the auto/light truck market.

Cabin Air Filters

AMSOIL now carries the entire WIX line of high-efficiency cabin interior air filters for passenger cars and light trucks. See Cabin Air Filter Installations (2MB PDF).

Additional Information

WIX filters are supplemental to AMSOIL Ea filters, but now AMSOIL will offers WIX filtration products that cross to an Ea filter. With the exception of WIX lube filters, all WIX filters should be changed in accordance with original equipment manufacturer’s (OEM) recommendations. WIX lube filter change intervals are extended OEM recommendations to match the drain intervals of AMSOIL XL Motor oil.

WIX Racing Filters

AMSOIL is carrying WIX racing filters in addition to filters for more common automotive and light truck applications. WIX has been a part of racing and NASCAR for many years, both as a sponsor and in the race cars. The company’s long-standing relationship with NASCAR not only demonstrates that WIX filters are high-quality products, but it also shows WIX’s dedication to racing, making it a perfect match for AMSOIL.
