Thank you for the further details, browndo!Took my car to Able Chevrolet on Thursday 3-17-16 to have my oil level confirmed for GM. My car was serviced by Shellworth twice, the initial oil change is when the burnt oil smell first became noticeable. Returned the car dealer confirmed oil was over the max level. When I got home I rechecked the oil and the level was at the max level. I personally removed about 12 ounces with a transfer pump. I complained to GM and we agreed to have the car checked at Able Chevrolet, who confirmed my oil level was correct. They also confirmed I have no leaks. The smell is still present if I do some spirited acceleration and come to a stop and the vents are on.
