i think you guys are misinterpreting the oil level readout a bit. it's not meant to show 50%,75%,100%, etc. Any value between the 2 arrows means you are at an acceptable level of oil for driving. Above the top arrow means you are overfilled, and below the bottom arrow means you are low, somewhere between .5 and 1 quart.
This means that you aren't necessarily going to see the indicator at the very top after an oil change, it just means the dealer filled the car to the midpoint of the acceptable range.
