AMSOIL Ea Oil Filters provide superior oil filtration for vehicles in the auto/light truck market.
Ea Oil Filters feature advanced full-synthetic nanofiber technology and rank among the most efficient filters available for the auto/light-truck market. When used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for extended service life:
• Ea Filters designated with product code Ea15K are recommended for 15,000 miles/one year, whichever comes first, in normal or severe service.
• 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.
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).
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 Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing filter lines. They provide convenience and cost savings through extended service intervals.
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.

My husband uses these in all our gasoline and diesel vehicles.
Once a year changes make these an excellent value.
Re: Cost efficient maintenance
AMSOIL Ea Oil Filters are recommended for 25,000 miles/12 months or 15,000 miles/12 months, depending on application. AMSOIL recommends using Ea Oil Filters especially for extended oil drain intervals. Made of fully synthetic media with greater filtering efficiency and dirt-holding capacity than conventional filters.

This filter has allowed me to take advantage of the signature series oil's 1 year drain interval by extending the visits to oil change
shop. This saves a lot of time and money.
Too bad that they don't make it for all makes and models. Leaving with options like WIX or MANN filters, which requires frequent changes. It's OKAY for DIY's but its a messy thing.
