Oil Leak
Dark brown or black spots under the engine usually mean oil is escaping somewhere. The amount and location tell you how urgent it is.
Should you keep driving?
A small seep can usually wait for inspection, but active dripping or a low oil level can damage the engine quickly.
Common causes

Oil drain plug or filterLoose or damaged service parts can leak right after an oil change.
Oil pan gasketLeaks near the bottom of the engine often come from the pan or its gasket.
