I drained the oil before I changed the filter. My driveway is not "perfectly" level (but close) so I fighued there was just some residual oil that didn't drain out. At times when I check it it seems to right up to the "max" and at others it seems over. Guess it depends on how level the car is setting when it's checked and how hot it is.
FYI: I discovered that Exxon & Havoline are both selling synthethic grade oils now at a $1 less per quart than Mobil or Castorl.
