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 decent 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 particles in the 5 to 20 micron range.
AMSOIL Ea By-pass Oil Filters remove particles 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, and more often.
