Mine also does this. It only did it occasionally with penzoil 5w20 or Schaeffer's 5w30, but since I put in the Castrol syntec blend 5w20 it has done it EVERY morning! I have only put about 300 miles on this oil, but I still think I am going to dump it today! My choices are Mobil 1 0w20...

I know that 2k oil changes are unnecassary, but my question is would 2k OCI with Castrol or penzoil conventional 5w20 offer similar protection to a synthetic at 5k OCI? I do not want to go past 5k miles while under warranty. My driving consists of some around town with a daily higway commute of...
