Burning oil produces blue smoke. Generally, it's best to keep the oil in the crankcase and not add it to the intake as burning oil can damage spark plugs, O2 sensors and catalytic converters. If you're adding the oil to the crankcase but the engine burns the oil, it may be overfilled or you may have an engine or PCV problem.
