Engine oil loss without visible smoke might indicate a leak or the oil is being consumed internally due to worn engine components. Check for leaks under the vehicle and around the oil filter and drain plug. If no leaks are spotted, the problem may lie with worn piston rings, valve seals, or a breached head gasket, allowing oil to seep into combustion chambers or the coolant system. Regularly inspect your vehicle and consult a mechanic for a comprehensive diagnosis to prevent potential engine damage.
