AMSOIL Bypass Oil Filter
The AMSOIL Bypass Oil Filter is an advanced filtration device designed to provide superior filtration for your engine's oil, reducing wear and extending oil life by removing contaminants with nearly 100% efficiency for particles 2 microns and larger.
AMSOIL Bypass Oil Filters
Engineered for Outstanding Oil Filtration Efficiency
AMSOIL Bypass Oil Filters provide maximum filtration protection against wear and oil contamination. Working in conjunction with the engine’s full-flow oil filter, AMSOIL Bypass Filters operate by filtering oil on a “partial-flow” basis. They draw less than 5 percent of the oil sump’s capacity at any time and trap the extremely small, wear-causing contaminants that full-flow filters can’t remove. AMSOIL Bypass Filters typically filter all of the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
Higher Efficiency
AMSOIL Bypass Filters have an absolute efficiency of 98.7percent at two microns. This highly efficient filter provides exceptional filtration performance, removing all the particles known to reduce engine life.
Superior Construction
AMSOIL Bypass Filters have a marine powder-coated exterior and an anti-corrosion coated base plate to provide excellent corrosion protection. AMSOIL Bypass Filters feature a nitrile HNBR gasket, a silicone anti-drain valve and proprietary high efficiency media.
Filter Service Intervals
AMSOIL Bypass Filters offer long service life. Do not exceed the limits listed in the chart below.

Increased Oil Capacity
The increased fluid system capacity and filtration life provide improved oil cooling and ensure that equipment constantly runs on highly filtered oil. Engine efficiency is increased, providing extended engine life.
Soot Removal
Our high-efficiency bypass filter element also removes soot particles two microns and larger, eliminating abrasive wear from soot agglomeration.

AMSOIL Bypass Filter Application Information

a. Make sure to check oil level with engine oil dipstick to ensure proper level. This additional volume is an estimate and should be properly evaluated using the dipstick. b. Filters can be used on sumps of larger capacity but may require more frequent replacement.
