Smells like burning oil
Looks like it's time to refresh the oil pan/sump seal (it's RTV, not a gasket) on the 2008 Saturn Astra.

Transmission end (probably the origin of the burning oil smell)
Near the oil level sensor on rear of pan/sump
Not a terribly difficult job, but I don't have a lift, so I'll have to put the car on jack stands in the driveway and do the job from the ground.😐
