The use of these pumps is quite varied, oil from the engine, oil from the power steering, oil from the master cylinder. You can even use it to bleed the brakes with the adapter supplied. Mine is a hand pump type but if you have compressed air available you can get one that you hook up to air line. Make sure you get one that can hold eight litres or more, mine takes ten I think.
Unscrew the filter and leave it in its hole to drain while the oil is extracted then refill the engine pouring the oil down the filter hole, replace the filter and O-rings and Bobs your uncle.
Then pour the oil into the oil containers you just emptied and take them to the recycle depot. Nice, clean and easy.
