Did not know Saab would go that fast. Check for leaking oil filter,drain plug ect.
If this just happened after service take it back and get it checked.
Believe it or not...SAAB made aeroplanes
Should have kept it up!

Don't drive it . Check trans fluid and coolant....again.
possibly oil spill by lube tech
Check oil pressure sensor too for leak.
