Milwaukee Institute Tests AMSOIL EaBP90 Spin-On By-Pass Oil Filter

How To Make Any Engine Last Up To 60% Longer.
AMSOIL EaBP90 Spin-On By-Pass Oil Filter Test Results Graph

Experts agree that the greatest amount of engine wear is due to contaminants that are in the 5-20 micron range. To give a frame of reference, these particles are about one-tenth to one-quarter the diameter of a human hair.

The Fluid Power Institute of the Milwaukee School of Engineering conducted a study to evaluate the filtering efficiency of the AMSOIL EaBP90 By-Pass Oil Filter Element. The graph on this page illustrates the results of this study. The values reflect the beta-ratios (the quotient of the particles in the oil before it is filtered compared to the particles present after the oil is filtered) of each filter over 15 different sampling intervals. In simpler language, the graph shows the average percentage of particles removed by the EaBP90 By-pass Filter compared to four of the nation's top-selling full-flow filters.

If 60% of all engine wear comes from particles in the 5-20 micron range, this study makes it very clear just how dramatically an AMSOIL By-Pass Filter can extend the service life of your engine. The EaBP90 Filter Element eliminates over 99% of these tiny, engine-damaging particles. Over the entire span of these particle sizes, the AMSOIL By-Pass Filter removes 21.9% to 99.9% more contaminants than conventional full-flow filters. in fact, below 10 microns, only one filter removed any particles to any measurable degree, and this was at the extremely nominal rate of 14%.

In light of this study, you can certainly look at the AMSOIL By-Pass Filter as very valuable investment. Hypothetically, if 60% of engine wear come from 5-20 micron contaminants, then the AMSOIL EaBP90 Filter Element extends your engine's service life by 13%-60%. You can of that in more real terms as 13,000 to 60,000 more miles for your vehicle (assuming an average service life of 100,000 miles). For most people, that's six more years of driving.

The test was conducted under the direction of Tom Wanke, Director, Fluid Power Institute, Milwaukee School of Engineering.
