The filter I cut in half at 180,000 miles EASILY had 50% life.
Consider the tiny inline filters of yesteryear could last 10-20,000 miles and were maybe 1/10 the lengrh and 1/10 the width. That means 10x10x10 or 1000x the filter media so yes: lifetime.
The inlet side of the filter media was FILTHY! Like squid ink black but the outlet side looked new and there was no visible film and no sign of flow restriction.
My original filter is at 203k mi. and I see no need to replace preemptively. When I'm "in the area" I will pull it open and replace the o-ring that is the normal failure mode of the FPR.
I bought a new FPR+ filter using the same logic about not expensive enough not to however during postmortem discover that the $65 FPR/filter were perfectly ok but the 40¢ o-ring was shot.
$65 is a decent meal out with the wife. (Also I've come up with half a dozen pennies on the dollar repair for e53; example: 17¢ fix for $230 disa or $12 fix for $225 door lock actuator or 40¢ fix for $65 FPR or 40¢ fix for $90 fuel sender unit.
The DLA fix alone saved $872 on wife's e53. So yeah; partly because I'm just used to fix vs. repair even the not so expensive jobs get the cheap route.
