Does anyone know if there is an official GM service bulletin for the oil level/capacity issue?

Had my oil changed at 500 miles and checked oil yesterday, after a drive and for first time since the oil change (800 miles now). Level is about 5/8" above top of hatched area.

What volume does the hatched area represent? I've got to suck some oil out of the reservoir today.

There are a few threads on this but how long did you wait after you turned off the motor to check the level?

I'll try to find the sticky. Ok here is the master list sticky and just go to engine maintenance. A lot of great info in the sticky.
On my car I use a little over 9 to get it about 1/2 on marks at 10 min after turning off motor once up to temp. But it really depends how much you get out of the car. I uses race ramps and the tail is still on the ground. A lift at a dealer may yield a slightly different amount. Also, and I hate to say it, I doubt the tech is warming up the car before checking and topping off.

Also make sure you got Mobil 1, there has been a lot of confusion at the dealer level about what oil to use.

I waited 7-8 minutes after I turned it off. The dealer was aware of the Mobil 1 requirement. Also, I walked out to the service bay and said to the tech "Mobil 1, right?". He said yes.

Thanks 03 Silver and JC 2004 for those links. I appreciate your help. I read those posts some time ago. I was really hoping to know if GM has issued an official service bulletin to dealers about the issue.
