E46 (1999 - 2006)
6am. Dark outside. Groggy and cranky en route to Orlando, a 4 hour drive.
Stop at gas station to add oil. Due to being groggy and cranky, not wearing glasses, I pour oil into ATF tank. YIKES! Once realized it, stuffed it with paper towels to absorb it out.
Car didnt explode, so...
