How easily air, oil or fuel flows through the filter. Minimising resistance to flow ensures that the engine is never starved of air, oil or fuel.
Poor flow in a filter deprives engines of their vital needs, causing them to work harder, lose power and create rapid engine wear over shorter periods.
Should the oil filter become blocked. the valve will open allowing oil to flow into the engine. (Unfiltered oil is better than no oil.)
Generally a filter with more media has the ability to trap more contaminants than one with less. Few pleats means little media and low capacity. Irrespective, the media must contain the appropriate resins and compounds.
Given the importance of efficiency, life and flow, regular filter changes with a good quality filter provide optimum performance and engine life.
Make sure correct filter was installed as per instructions.
How long a filter lasts before clogging up. Dust-holding capacity of the filter determines how long its life is. The more high-quality paper inside the filter the more dirt it will hold and the longer it will last.
It stops oil from draining out of filter and oil galleries when the engine is shut down and aids quick flow of oil to engine on start up. Not all filters require anti drain back valve due to the construction of the engine.
