I never understand these threads on oil overfills. If it is overfilled and you are in the least bit concerned (and you must be since you started this thread), take it back to the dealer. A quick alternative, would be to pump out the overfilled amount with a dip stick pump. Cheap and easy to use. If that is not an option put the car up on ramps and drain enough out to get the level in the crosshatched area. If you take too much you can always add a little to adjust. All the dipsticks I have ever seen on any car or truck says "DO NOT OVERFILL." They don't say "Do Not Overfill Except for the Allowable Overfill." They do not say, "Don't Worry About Overfilling Just a Little Bit." They do not say, "Close the Hood and Forget It." I sleep well when the oil in my engines is within the safe zone on the dipstick.
