It may after a time build up carbon deposits on the cooler parts of the exhaust as it exits,much like burning wood in a wood stove builds up creosote in the chimney over time. Synthetic oils build up less hard carbon deposits generally, and make a little less smoke, but they cost more.
As the MopedWhiz said....a 2-stroke need no crankcase oil. The oil is supplied continually to the moving parts by the fuel whistling thru the crankcase. don-ohio (:^)
