Premium Synthetic Technology Offers Greater Filtration Efficiency and Capacity – Designed for Extended Oil Change Intervals in Cars and Light Trucks
The advanced full synthetic media in AMSOIL Ea Extended-Life Engine Oil Filters (Product Codes: EaO, Ea15K) make them the highest efficiency filters available for car and light truck gasoline and diesel engines. Filtration testing at numerous test facilities provided data that substantiates a near perfect absolute efficiency rating for AMSOIL Ea Oil Filters, hence the name Ea (Ea stands for Absolute Efficiency). This technology outperforms the cellulose media found in conventional oil filters.
AMSOIL Ea Extended-Life Synthetic Engine Oil Filters provide a filtration efficiency of 98.7 percent, whereas competitive filters demonstrate an efficiency rating as low as 51 percent (see graph in Product Details below). In other words, these premium oil filters trap and hold a greater amount of small, wear-causing contaminants compared to conventional filters, helping to reduce engine wear. And, for increased convenience, AMSOIL Ea Oil Filters are designed for extended oil change intervals and are the best filter available for long-life synthetic oil, such as AMSOIL. When used in conjunction with AMSOIL synthetic engine oils, AMSOIL Ea Oil Filters are guaranteed for an extended service life of up to 15,000 miles or up to 25,000 miles, depending on application.

AMSOIL Ea Extended Life Synthetic Engine Oil Filters have lower restriction than conventional cellulose media filters. Their small synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction and, therefore, providing a higher level of engine protection.
As shown in the photos, cellulose fibers are larger than the synthetic fibers and have larger spaces between the fibers, causing the contaminants to load inside the depth of the media and plug the flow path, resulting in higher restriction and less capacity. The fibers in synthetic media have submicron diameters and small inter-fiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction. This results in greater efficiency and capacity than cellulose filters, as well as better durability and longer service life. Lower restriction decreases engine wear.
And, 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.
Oil Filtration Basics
Clean oil is vital to engine performance and durability. Oil must lubricate, cool and clean the engine as it circulates. In order to remain effective, oil must be filtered as it cycles. Internal sources of oil contamination include wear products from the rubbing surfaces of the engine, blow by gases leaking past the rings of the pistons and degradation of the oil itself. The oil filter removes these contaminants, preventing them from reaching sensitive engine parts, without restricting normal oil flow to the various parts of the engine requiring lubrication. A filter must perform well in the areas of efficiency, capacity, flow and filter life.
Efficiency is the filter’s ability to capture contaminants. The more efficient an oil filter is, the more contaminants it will remove from the oil. To make an oil filter more efficient, the spaces between the fibers in the media are made smaller, creating more resistance and limiting the oil’s ability to flow through the filter. Achieving maximum efficiency along with limited resistance is critical to good filtration.
As shown on the graph, AMSOIL Ea Oil Filters achieve a near-perfect absolute efficiency rating, according to industry standard ISO 4548-12 testing. AMSOIL Ea Extended Life Engine Oil Filters provide filtration efficiency to 98.7 percent at 20 microns, whereas competitive filters demonstrate an efficiency rating as low as 51 percent. AMSOIL Ea Engine Oil Filters rank among the most efficient filters available for cars and light trucks.
Oil Filter Efficiency ISO 4548-12 Testing
A filter’s capacity refers to the amount of contaminants a filter can hold and still remain effective. When an oil filter reaches maximum capacity, the oil bypasses the filter and continues to circulate, unfiltered, throughout the engine. When an oil filter reaches maximum capacity it also reaches the end of its life and must be changed. AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing oil filters do. They provide convenience and cost savings through extended service intervals.
Oil Filter Flow
Proper oil flow is essential to keep moving parts lubricated at all times. A filter without adequate flow properties can cause catastrophic engine failure. Flow is restricted as the spacing in the filter media is made smaller to provide greater efficiency. The synthetic fibers in AMSOIL Ea Oil Filters allow maximum efficiency without restricting oil flow. This provides unsurpassed cold-start performance and ensures proper levels of lubrication throughout the engine.
Here’s how the synthetic technology works: Imagine two filtration media, a chain link fence and a mosquito net. Each is required to stop contaminants, in this case tennis balls. A tennis ball will fit quite nicely into an opening of a chain link fence, but will obstruct the hole almost 100 percent.
Now, imagine a tennis ball covering a mosquito net. The tennis ball, at the point of contact with the netting, will obstruct much less filter area than the chain link fence example. In fact, air will flow around the tennis ball all the way to the point of contact. It will take many more particles to obstruct the netting surface area than the chain link fence.
AMSOIL Ea Extended-Life Engine 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 AMSOIL Ea Engine 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. AMSOIL 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. AMSOIL Ea Oil Filters are constructed with HNBR gaskets that are fully tested over 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-drainback valve.
Designed for Extended Oil Change Intervals
When used in conjunction with AMSOIL synthetic engine oils, AMSOIL Ea Oil Filters are guaranteed for extended service life:
- Ea Oil Filters designated with the product code Ea15K are recommended for 15,000 miles/one year, whichever comes first, in normal or severe service.
- Ea Oil Filters designated with the 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.
Note: For your convenience, AMSOIL Signature Series Synthetic Long-Life Engine Oil has the same oil drain interval as AMSOIL EaO Oil Filters.
When AMSOIL Ea Oil Filters are used with a motor oil other than an extended-drain AMSOIL motor oil, the filter should be changed according to the vehicle manufacturer’s recommendation.
AMSOIL Ea Extended Life Oil Filters (EaO, Ea15K) provide superior oil filtration for car and light truck gasoline and diesel engines. The AMSOIL Online Product Application Guide will help you find the correct oil filter for your car or truck.
