1999 Ford Mustang GT 4.6L Chrome Yellow, 308,143 miles as of 1/17/2012.
I ran almost exclusively Castrol GTX 5w30 with Fram Extra Guard (OCOD) for a few years, then switched to Motorcraft FL820S or Purolator filters. Oil was changed about 6,000-7,000 on average. Obviously the Fram filters did not cause any problems, I just didn't like the startup noise after about 5,000 miles because the ADBV doesn't last.
It's semi-retired now and only goes about 2,000-3,000 miles per year.
