AMSOIL Dual-Gard™ Bypass Filter System

See Bypass Installation Samples

The Ea Bypass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea Bypass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

Why Bypass Oil Filtration Matters

As an authorized AMSOIL dealer, we understand how important it is to protect your engine components. That’s why we recommend upgrading to a bypass oil filter system. Unlike a standard full-flow oil filter, a bypass system removes much smaller contaminants, improving overall oil filtration and reducing wear on your engine.

Benefits of a Bypass Oil Filter

One of the biggest advantages of bypass oil filters is the extended oil change interval. Because the bypass filter traps finer particles, your oil stays cleaner longer. That means fewer oil changes over time and less oil waste. It’s better for your wallet and the environment.

Bypass oil filtration also helps reduce long-term engine wear. The filter element in these systems captures soot, metal, and other debris that can harm your oil pump, bearings, and other sensitive components. Cleaner oil means a longer engine life.

Better Filtration Technology for Better Results

Modern filtration technology has made bypass systems more efficient and easier to install. These filters work alongside your existing full-flow oil filter, offering a second line of defense. They don’t restrict oil flow to critical parts but still remove particles down to a few microns in size.

We believe in taking steps that pay off in the long run. A bypass oil filter system is one of those smart upgrades. It improves the overall efficiency of your oil changes, protects vital engine components, and helps you get more out of every drop of oil.

For anyone serious about engine protection, bypass filtration is worth a look. Let us help you find the right system for your vehicle and keep your engine running strong for miles to come.

Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes.

Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity along with superior corrosion resistance. AMSOIL EaBP Filters have a marine powder coated exterior; and their zinc-dichromate base plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two stage pleated and layered cellulose/full synthetic media has an efficiency rating of 98.7 percent at two microns.

Longer Lasting
AMSOIL Bypass Filters can be utilized over an extended period of mileage, hours or years as outlined in the Chart below. Extended oil drain intervals should always be accompanied by an oil analysis program.

Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on clean oil. Engine efficiency is increased, providing extended engine life.

Soot Removal
AMSOIL has designed a high-efficiency bypass filter element that is also a soot removal device. AMSOIL Ea Bypass Filters use a synthetic/cellulose sandwiched media. The inner layer of the element is composed of a highly efficient cellulose media covered with a full synthetic media outer layer. These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.
