If you are considering using a vacuum pump most are plastic and you CANNOT remove hot oil with them. The "best" way is to drain the oil from a hot motor, the flushing action removes the sludge and dirt and metal that collects on the bottom while most of the dirt is still in suspension in the old oil. The vacuum units give you the impression you don't even have to get under the car to change the oil. They seem to forget you still have to change the oil filter! Besides, when you are under the car you get a chance to inspect things that normally can't be seen.
