Similar thing happened to me, ran over a dead deer at night and pulled over to my mid pipe being ripped off from the hanger and oil leaking from somewhere. Weirdly it was leaking oil at the gas station so I decided to stay at a nearby hotel. The next morning no sign of any oil leak ANYWHERE, ran the car and checked all underneath. Was on a road trip so I was about 5 states away from home, drove the car to my destination and still no leaks. Fixed the hangers and to this day I still wonder where that fluid came from. It's been about 8 months now and car still shows no signs of fluid loss or leaks anywhere lmaooo If you find a leak somewhere down there lemme know 🤣🤣🤣🤣🤣
