It's supposed to be a settling time for the oil to get up to temp and all through the system...air out etc so the level can be checked and topped up in the reservoir if needed. Revving kind of seems the opposite of the intention of the process.


I expect at 1000-1500 it's not a big deal but I would be freaking out at 3000 and quickly getting my car out of there. I am super curious as what reason the tech/service genius gave for revving the car. Would also like to get my hands on the actual GM procedure for this.
