Mine had the original filter when I changed it around 22k miles (thanks F-M). It ran fine before, ran fine after.
I also try to keep "good" gas in it. Don't fill up if the tanker is at the gas station(**** at bottom of the tanks has been stirred up), try to fill up at larger/busy stations that turn fuel over quickly, and always run 87, since stations sell around 5x as much 87 as the premium blends, so the gas is a lot fresher. 93 at small stations(especially in rural areas where nobody has stuff that needs premium) can be sitting around for a l-o-n-g time. The c-store in schroon gets the 91 tank filled in october and isn't empty until spring. During the summer it goes for a 3-4 weeks, where the 87 is refilled at least once a week.
