The oil line to the aftermarket oil filter broke on one I no longer have. It was dark and I didn't have lights in my instruments, and it wasn't until I heard knocking in the motor that I realized something was wrong.
I walked to a gas station and bought oil. By time I had driven to that station it was knocking again. I bought a brass plug to stop the oil filter, filled it back up and went on my way. Still knocking until I replaced a rod bearing.
That's the truck I sold 20+ years ago to buy an engagement ring. Still have both the ring and the wife. I know where the truck is, but haven't ever felt the need to get that one back.
