Aircraft
Aircraft X recently had oil change; dipstick said 11 qts. of fresh oil in preflight.Start was fine; runup had good oil pressure; and no abnormalities. Upon liftoff; cabin began filling with smoke; and received a call from Tower that we were smoking and trailing oil. Circled back to Runway XX; made a short approach; uneventful landing; and taxied back to the hangar. Oil was smoking and dripping from the cowl; covering the fuselage; and a large amount was noticed in the area we had started the aircraft as well. Checked dipstick about an hour later; and it showed no oil.
C206 pilot reported smoke and a loss of oil on takeoff that resulted in a return to the departure airport.
