Consider Bypass Filtration Protection

AMSOIL Bypass Systems offer top-of-the-line protection

Bypass oil filtration features a secondary filter with the purpose of eliminating nearly all contaminants from engine oil. Bypass filters have high capacities and eliminate much smaller particles than full-flow filters. They reduce engine wear and increase oil volume, but their high efficiencies mean they also have higher restriction and must be used in conjunction with a full-flow filter.

How it Works

Bypass filters operate by filtering oil on a “partial-flow” basis. They draw approximately 10 percent of the oil pump’s capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can’t remove. Bypass filters have a high pressure differential, causing the oil to flow through them very slowly and allowing for the removal of smaller contaminants, including soot. It is called bypass filtration because the oil flows from the bypass filter back to the sump, bypassing the engine. This continual process eventually makes all the oil analytically clean, reduces long-term wear and can extend oil drain intervals.

AMSOIL Bypass Filtration Benefits

  • Significantly Extended Engine Life

The majority of engine wear is caused by particles in the 5-20 micron range. Because AMSOIL Ea® Bypass Filters effectively remove contaminants down to 2 microns, engines receive the ultimate in wear protection. Less engine wear keeps the engine in better condition, extending its life.

  • Efficient Small-Particle and Soot Removal

The high-efficiency Ea Bypass Filter element is 98.7 percent effective at removing particles down to 2 microns, helping extend engine life. It is also a very effective soot-removal device.

  • Reduced Maintenance Costs

AMSOIL Bypass Systems provide a dramatic increase in engine protection, helping avoid costly repairs associated with engine wear.

  • Improved Oil Cooling

By installing an additional filter, the engine system has the capacity to hold more oil. With increased oil capacity, the oil filtration system contains more fluid through which it can disperse heat from the engine. This allows the engine and the oil to run cooler.

  • Extended Drain Intervals

Ea Bypass Filters can help users extend their oil drain intervals. Make sure to use oil analysis when extending oil drain intervals.

Outstanding Protection at an Affordable Price

Competing single-remote bypass systems designed for Ford*, GM* and RAM* turbodiesel vehicles range in price from $250 to more than $700, with an average largely over $450. Most AMSOIL Single-Remote and Dual-Remote Bypass Systems carry an MSRP below the market average.

Competing heavy-duty bypass systems range in price from $650 to more than $850. The premium-quality AMSOIL Heavy-Duty Bypass System (BMK30) and DUAL-GARD® Bypass System (BMK22) have MSRPs almost half the market average.

AMSOIL offers complete bypass systems for certain popular applications that include all components necessary for installation (including parts, hose, filters and installation instructions). We also offer universal bypass systems that can be customized with different additional parts to fit specific applications.

Easy Installation

AMSOIL Bypass Oil Filtration Systems are relatively easy to install and easy to maintain. Do-it-yourself installation instructions are provided.

Durable Construction

AMSOIL Bypass Systems and Ea Bypass Filters are built tough to withstand the most severe operating conditions.
