You’ve probably walked outside, spotted a dark little blot under your car, and thought, “Huh. That wasn’t there last week”. Maybe you wiped it up, maybe you ignored it, or maybe you made the classic mistake of sniffing it like some kind of driveway sommelier. But here you are now, wondering whether that weekly drip is just a harmless quirk or your engine’s cry for help. Spoiler: your engine never cries for fun.
