Low-Profile, Portable "Oil Changer"
After he built a new shop, Scott Smith, Blue Earth, Minn., didn't want the mess that comes with changing oil and catching it in buckets or trays. So he built a low-profile, portable "oil changer" that drains away used oil and also disposes of it using compressed air.
  He used heavy, 3/16-in. thick steel plate to make a 16-gal. tank, adding caster wheels to each end. A 6-ft. long, 2-in. dia. pipe extends out one end of the tank. A drain pan equipped with a quick-tach adapter fits into an elbow at the end of the pipe.
  When changing oil, Smith rolls the tank under the vehicle and pulls the drain plug to drain oil into the pan. After the oil drains into the tank, the pan is removed and replaced by a pressure regulator, also on a quick-tach fitting.
  He then rolls the tank over to an air compressor, stands the tank up on end, and hooks a hose to a fitting on the regulator. The hose leads to a 300-gal. tank outside the building, where oil is picked up for recycling. The last step is to hook an air hose up to a fitting at the top of the tank. Air is forced through a tube that extends from the fitting almost down to the bottom of the tank. It takes only a few pounds of pressure to force the oil out of the tank.
