The AMSOIL Dual-Gard By-Pass Oil Filtration System
links two AMSOIL By-Pass Filter Elements together for engines
with sump capacities over 20 quarts. Allows fast and simple servicing
with spin-on elements.
Wear tests have shown particles of contamination
in the sub-20-micron range are most harmful to rings and bearings.
Most trucks are sold with a full-flow filter as their only oil
cleansing unit. A study by the Milwaukee School of Engineering
determined the filtering efficiency of four top selling full-flow
filters compared with a BE-90 AMSOIL Spin-On By-Pass Filter.
Versatility:
Accommodates any two AMSOIL Spin-On By-Pass Filter Elements. Their
unique internal flow director and follower spring system provide
a nonchanneling filter media.
Convenience:
Elements spin on and off for fast, neat filter changes.
Protection:
The stacked disc type by-pass filter has been shown to reduce
piston ring and rod/main bearing wear 75% to 91% (Society of Automotive
Engineers paper 881826).
By-Pass Safety:
A metering orifice inside the mount controls oil flow so that
it never draws more than 10% of the oil pump's capacity. At an
engine speed of 45 mph, the AMSOIL DUAL-GARD By-Pass Filter cleans
all of the oil in the system every 5-10 minutes (depending on
engine RPM, sump size, and oil pump ratio).
The DUAL-GARD Mounting
Kit:
The BMK-12 contains a mount, mounting hardward, a restriction
fitting, and two 3/4" - 16 to 1/4" J.I.C. fittings.
Complete installation instructions are included along with an
additional parts list of plumbing hose and fittings available
from seperately from AMSOIL. Spin-on filter elements, available
in three sizes, should be purchased seperately in pairs based
on sump size or available room in the engine compartment. The
following is merely a guide, since the large the element used,
the less frequently it will need to be changed.
For a crankcase sump of 15 to 18 quarts use
2 BE-90 filter elements.
For a crankcase sump of 15 to 30 quarts use
2 BE-100 filter elements.
For a crankcase sump of 15 to 42 quarts use
2 BE-110 filter elements
Your AMSOIL By-Pass Filters will last twice
as long as your regular engine filter, so change them half as
often.

Normal Service Life:
When used in conjunction with AMSOIL motor oil and an EaO
or Donaldson Endurance filter, the EaBP should be changed
every other full flow filter change up to 60,000 miles.
When used with other brands of motor oil or full flow filters,
the EaBP filter should be changed every other full flow
filter change. AMSOIL recommends using oil analysis when
extending oil drain intervals.
