That is not unusual for the miles to be over 11,000 with the oil life monitor. You can check it anytime you want in your DIC. GM did years of testing and validation with cooperation from the oil industry to set the computer calculations for oil life. The only factors it cannot account for is the driving conditions such as Dusty or dirty driving conditions, in that case you need to go by the severe use 3000 mile schedule. It does use engine loading as a factor in determining life, I have seen in pickups that do alot of towing it needing an oil change in as short as 4000 miles...
In most cases for the average user you can go by their oil life monitor, but if you are scared of using it, you can do as I do and change it when it gets to 50%.
