I ALWAYS change the filter when I change my oil, in anything that has a filter.
BUT I get the impression from this thread that many feel that if one would NOT change the filter whe he changes his oil, that somehow the new oil causes whatever the filter holds, to go back into suspension in the new oil, and therefore end up back in the engine.
Would this be the case? Somehow I doubt it, but have nothing but limited common sense to rely on...
Seems to me the risk of not changing one's oil filter would be that it would clog up and go into bypass mode, if bypass mode exists in a given application, or worse clog up and starve the engine of oil...bye, bye bearings, etc.
Sooooooo...if one would elect NOT to change his oil filter each time he changes his oil (I know one guy that told me he changes his oil EVERY 12 OPERATING HOURS on one of his tractors) how much harm might we expect, provided that the oil filter is not clogging up too bad?
Just thinking out loud as like I said, I do change my filters when I change my oils...
But if someone told me he did not change his oil filter more frequently than recommended by the manufacturer, but did change his oil at a greater frequency, I am not sure I could fault him too much...heck, worst thing he could do is change back to NOT changing his oil as much as he does, and to start following the manufacturer's oil change recommendations...
