Absolute Efficiency Ea®

Superior Oil Filtration for Cars and Light Trucks

Amsoil Ea Oil Filters (EaO, Ea15K) have one of the best efficiency ratings in the automotive market providing a filtering efficiency of 98.7 percent at 20 microns. Use PART NUMBER dropdown to select filter number.

Amsoil Ea® Oil Filters (EAO, EA15K) feature advanced full-synthetic media that traps and holds a greater amount of small, wear-causing contaminants compared to conventional filters. They provide extended service intervals for increased convenience, while helping reduce engine wear.

Absolute Efficiency

Efficiency is the filter's ability to capture contaminants. The more efficient a filter is, the more contaminants it will remove from the oil. Amsoil Ea Oil Filters 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 (see graph).

Less Restriction

Proper oil flow is essential to keeping engine parts lubricated at all times. Amsoil Ea Oil Filters' synthetic fibers are smaller than the fibers used in traditional filters, allowing Ea Oil Filters to provide 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. They last longer and ensure the oil is properly filtered.

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.

Ea Oil Filters' full-synthetic media technology is resin-free to resist degradation from hot oil. 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. They feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting, premium-grade silicone anti-drainback valve.
