Narrative:

Soon after takeoff we noticed smoke coming out of the overhead vents in the cockpit and also smoke in the cabin. The smoke had an oil smell. We remained in left closed traffic; selected ram on the ecs [environmental control system] panel and landed. Switching to ram stopped the flow of smoke out of the vents. During the roll out we were in radio contact with the airport fire truck and he verified that no smoke was visible from the outside of our airplane. We elected to shut down and evacuate on the taxiway. The passenger were transported back to the FBO while the fire fighters verified no fire existed. A smoky haze remained in the cabin for several minutes after everyone had deplaned.
