Oil Filters
Filter manufacturers claim that dirt particles in the 10-20 micron range do the most damage to bearings, cylinders, the oil pump, and other moving engine parts. Most off the shelf auto filters are rated to capture particles between the 25 and 40 micron range. In recent months, in order to get a higher retail price for their product and to gain a competitive advantage in a very price driven market, filter manufacturers have introduced new and improved filters that claim to filter out particles in the 10-20 micron range. In general, oil filters for cars and light trucks do not attempt to remove particles less than 10 microns.

Oil in a typical engine is designed to flow at a speed of three to four gallons per minute. Oil flow is needed for oil lubricating pressure to be maintained and heat to be dissipated. Oil filter design is limited regarding particle size because flow speed is critical to the operation of the engine. If the filter attempts to filter out the very small particles it will reduce oil flow speed thus reducing the lubricating and cooling ability of the oil system.

Oil filter manufacturers want the public to believe that oil filters remove all of the damaging, abrasive contaminants in an engine. Large, chunk particles generally settle to the bottom of the oil pan. It is the small particles that stay suspended in the oil. Small particles in the 5 to 10 micron range act like grinding compound. Whether we call particles 5 microns, 10 microns, or 20 microns, the oil filter simply does not and cannot trap all of the ferrous metal particles or the small particles.
