The only thing a used filter is "likely" to do is clog. The buildup of contaminants on the dirty side of the filter media increases their ability to trap ever finer particulates right up until that point. That is why a fuel pressure gauge (not the odometer) should be your main fuel filter monitoring tool. The primary filter on my 1st Gen has been in service over three years.
Oil filters are a different story.

That's why there is a drain on the bottom of the filter - to let the water out. Assuming there is any there to begin with. I've never seen more a few drops come out of my FW separator drains.

At minimum...fuel filter and oil/filter. I don't care what people say the injectors on a cr are so picky I'm gonna change my fuel filter at least every 10k miles. Filters are cheaper than a $2500+ set of injectors. Use a Baldwin pf7977 for fuel and a Donaldson elf7349 for oil.
