I haven't personally. Except on vehicles that have been totally abused and haven't had an oil change in forever, then you can actually feel how heavy the filter is as it's full of crud. But for $4 I won't worry about it. Friends with race cars always cut their old filters open to look for bits of bearing etc, but for normal use it's not something I ever bother with. If you have an older vehicle with high miles, maybe it's starting to lift a headgasket and coolant is getting into the oil etc. In fact I think that's what's up with my Civic CX. Runs fine, never overheats, no puddles of coolant under it. But it keeps losing coolant somewhere. I keep waiting for the oil on the dipstick to go milky, but so far nothing yet. It's quiet. Too quiet lol.
