I am still considering picking one of those oil extractors up....The lift is usually taken so it could definitely be helpful, too bad all the other cars I use have the oil filter on the bottom. Everyone who has ever changed oil outside knows it sucks when you open that drain plug and the oil comes out too fast and splatters everywhere including your face!! Or when you've got the drain pan positioned perfectly under the car and a gust of wind comes and the oil comes out sideways, no where near the drain pan all over the ground.

BTW, the ceiling in that garage is less then 9ft high
