| By-Pass Oil Filters & Mounting Kits Product Information Engine wear is caused by dirt
particles larger than 5 microns. The AMSOIL By-Pass Oil Filter
removes particles as small as 1/10 of a micron, virtually
eliminating engine wear. AMSOIL By-Pass Oil Filters filter all the
oil in a six-quart system in about five minutes at an average engine
speed equivalent to 45 mph.

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 ten percent of the oil 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 5 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 smaller than 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. Water contamination of the motor oil can
cause extreme engine damage. Water causes metal surface rust and
corrosion, which increases friction and wear and deteriorates the
close-fitting tolerances between engine components. In addition, water
reacts with other oil contaminants to form corrosive acids, which also
damage metal components. The AMSOIL By-Pass Filter removes water, 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 smaller than 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. That saves motorists time
and money and helps protect the environment by creating substantially less
used oil.
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.

"When we took this Chevrolet 396 engine
apart (using AMSOIL Synthetic 10W-40, Reusable Air Filter and
By-Pass Oil Filter), it was in the best condition of any engine I
have ever seen. It looked like it had about 80,000 miles on it
instead of over 535,000. The bearings were not even worn to the
brass and the rings were not worn out. It was clean inside, no
sludge or carbon at all."
