Frequently Asked Questions

  • Definitely Yes!  All engine have a primary lube oil filter to stop large particles from entering the oil passageways. However to maintain the flow rate and minimise the pressure drop across the element they compromise on the micron rating. They are usually in the range of 20 to 40 microns.  Smaller particles still pass through the pores of the element and enter the lube oil system. These particles may agglomerate over time and may eventually get caught by the barrier filter.  However the tiny particles in the range of 0.5 to 5 microns are the particles with are missed by the primary or even secondary 10 micron paper bypass filters.  These particles get caught between the engine friction parts such as piston ring and liner, bearing and crankshaft where the oil film thickness is 1 micron or lower. As a result bearing scuffing and liner wear takes place. The metal reacts with sulphur and oxygen to form acids which will adversely affect the oil additive package as well as cause engine wear. Filtek Centrifugal Oil Cleaners will remove 90% particles in the range of 0.5 microns to 2 microns thereby nearly doubling the oil life and increasing engine life by at least 50%.
