When diagnosing automobile exhaust smoke, technicians usually refer to the
vapor from water condensation as white smoke. Oil burning produces a blue
gray smoke that might be mistakenly called white smoke until you see the
difference. Black smoke is due to excessively rich fuel mixture. Lawn
mowers and other air cooled engines cannot produce the so called white smoke
caused by water vapor because there is no coolant to leak into the
combustion chamber and the muffler is too hot to allow water vapor
condensation. Any "white" or blue gray smoke from the exhaust on an air
cooled engine is from burning oil.
