Uses coolant - nonsense. If coolant is used, it's a problem.
Based on your pics and description the overfill reservoir has less coolant from the time it was topped off. That tells me you have a leak somewhere. Have you touched, smelled the leaking trail you got on concrete? Is it a bit greasy but watery to a touch? If so, it's coolant. This needs to be taken care ASAP to avoid overheating and/or extensive damage down the road. The leak could be coming from many areas (thermostat, water pump, hoses, turbo cooling lines, etc.,).
