There's still equipment out there, that don't require filters at every oil changesThe fact is the oil filter provides safe protection longer than the oil. Years ago the filter was changed every other oil change. Again, the analysis will tell you how effective the filters are (even the air filter). From many years of using oil analysis, I can tell you the oil filter will provide safe protection far beyond the life of the oil.
