PRODUCT DESCRIPTION
The AMSOIL By-Pass Oil Filter provides the best possible filtration protection against wear, oil degradation, rust and corrosion. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL By-Pass 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 and water that full-flow filters can’t remove. The AMSOIL By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

Reduces Wear
Approximately 60 percent of all engine wear is caused by dirt particles in the five to 20 micron range. These particles can get inside the precision clearances between engine components and cause severe damage. While full-flow oil filters generally stop contaminants no smaller than 25 to 40 microns, the AMSOIL By-Pass Filter effectively stops particles down to one micron in size, substantially reducing engine wear.

Prevents Oil Degradation, Rust and Corrosion
Water enters motor oil as a combustion by-product or as a condensate and can cause extreme engine damage, causing metal surface rust and corrosion that increases friction and wear and deteriorates the close-fitting tolerances between engine components. In addition, water reacts with other contaminants to form corrosive acids and sludge, which also damage metal components. The AMSOIL By-Pass Filter removes moisture and condensation, reducing the risk of oil degradation, engine rust and corrosion.

Extends Oil Drain Intervals
Because the AMSOIL By-Pass Oil Filter removes water and particles down to one micron, it significantly increases the time oil can safely be left in the engine. In fact, engines using AMSOIL Synthetic Motor Oil and an AMSOIL By-Pass Oil Filter routinely show much lower rates of engine wear – even when the oil is used for significantly longer drain intervals – than engines using conventional products and conventional oil drain intervals.

Dual Remote Filter System
The AMSOIL Dual Remote Oil Filtration System converts an engine’s full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount. The Dual Remote System provides superior filtration efficiency, increased oil capacity and improved oil filtration accessibility. See the G1092 brochure for more info on the Dual Remote Filtration System.

a. Filters can be used on sumps of larger capacity but then require more frequent replacement.  Full details on service life included with filter installation instructions

b. Data determined in a non-turbo gasoline engine with AMSOIL 100% Synthetic Motor Oil and AMSOIL Full-Flow Oil Filter.  Service life varies in other engines (turbo and diesel) and with other oils and filters.

NOTES:

1. Special adapters and hardware may be required for some installations. A universal mounting bracket is included with the kit, however, custom brackets may be required depending on your vehicle's equipment options or personal preferences in mounting locations."

2. Contact AMSOIL INC. Technical Service for instructions before installing on vehicles with cast aluminum oil pans.
