Amsoil Bypass Filter System
Oil filtration is critical to engine life. Abrasive particles in dirty oil can quickly destroy critical components and ruin precision clearances in an engine if not removed through filtration.
Today’s engines, however, are designed with smaller, lower capacity oil filters which are harder to get to for servicing. This means less efficient filtration and a reluctance to change filters at regular intervals, leading to a build-up of dirt in the oil.
The AMSOIL Dual Remote Oil Filtration System is designed to provide superior filtration efficiency, increase oil capacity and improve oil filter accessibility.

Superior Filtration Efficiency

A vehicle’s regular oil filter is a full-flow filter. This means that all the oil pumped by the engine must pass quickly through the filter before it reaches the engine. This high flow demand limits the size of particles conventional filters can effectively remove.
Particle size is measured in units called microns. A good full-flow filter will effectively remove particles down to about 25 microns. But studies have shown that over 60 percent of all engine wear is caused by parti-cles in the 5 to 20 micron range.
AMSOIL By-Pass Oil Filters remove particles down to less than one micron, keeping the oil free of virtually all wear-causing particles.
The dual remote system combines both full-flow and by-pass filtration on one convenient mount. With this system, all the oil is super-filtered more often.
