Modern oil filters remove particles by forcing the oil through paper-based media with very small ports. The technology behind this filtering media is a compromise that has remained relatively unchanged since the 1930s. While oil is necessary to remove these damaging particles, it is equally important that it flows back into the engine fast enough to lubricate all the moving parts.
A perfect oil filter media would stop all the particles down to 1-micron (about 1/70th the thickness of a human hair). Unfortunately, a filter with ports that small would also restrict the oil from returning to the engine fast enough, resulting in catastrophic equipment failure.
This is where FilterMAG saves the day.
The powerful rare earth magnets pull damaging metals as small as 2-micron to the side of the oil filter. They do not pass through the engine which means less engine wear.
Less engine wear means
longer engine life, including
longer periods of time before changing your oil. All of these factors help you save time, and money.
Filter media developments over the years have certainly increased the life cycle for oil filtration cartridges, but fluid dynamics require the ports in the media to remain 25-micron or larger.
An
SAE report by David R. Staley, General Motors Corp., states:
"
The smallest particles most popular filters captured with high efficiency are sized 25 to 40-micron, depending on the filter brand...[however] controlling the abrasive contaminants in the range of 2 to 22-micron in the lube oil is necessary for controlling engine wear."
These tests also confirmed that removal of particles down to 2-micron in size virtually stops the abrasion wear cycle.
