How To Evaluate Oil Filters
 

From Machinery Lubrication, a 8 min Noria video on how to evaluate oil filters, that covers the basics. So if we choose to use a more efficient filter, we know what else needs to be considered, lest we get into trouble in other areas that also need to be considered. http://www.machinerylubrication.com/...te-oil-filters

The Importance Of Filter Dirt Holding Capacity
 

More oil filter design info from Machinery Lubrication for pondering. The Importance of Dirt-Holding Capacity in Oil Filters http://www.machinerylubrication.com/...lding-capacity

Kinda looks like a filter media with a blend of cellulose & synthetic fiber, produce a water absorbing surface & depth loading media, whos synergistic sum result, is greater than the sum of the individuals!!!

Cellulose can absorb/remove & hold water & sludge, has a varying surface geomerty that has a lot of surface area, so sets up a lot of turbulence as the oil flows over & around its fibers pores, so can trap & hold larger particles & water, while the smaller diameter more uniform synthetic fiber media catch the finer particles for finer particle filtering & provide support strength over time, as the cellulose fibers weaken when it absorbs water or acids!!!! So the filtering ability/synergy of the Combination of both fiber types is overall greater than the ability of a filter media made exclusively of cellulose or synthetic fibers alone!!!!

Wear particle Size isn't the Only thing our filter needs to remove!!!! Water & acid by-products/sludge, need to be removed & held onto, so the oil can last longer. By being able to hold onto the sludge, it isn't available to hasten the oxidation/thickening breakdown of our oil, so our oil can last longer while doing a better job of preventing corrosion wear, as well as physical wear from large abrasive particles.

The filter needs to be able to do all this while providing/passing plenty of lubricant Volume, no matter the temperature/viscosity change of the oil (think cold high rpm starts), or when we get crazy & go WOT at throttle up!!!!

SO, our oil filter is plenty busy, Removing & Physically Holding Onto chemical & physically abrasive particles over its specified change interval, while the filter media is having to endure a lot of changing oil pump vibration pulses/flexing the filter media during our filter change interval, without weakening/distorting, collapsing, or rupturing!!!!!

More filter thoughts for consideration. Choose your oil filter wisely!!!
